BACKGROUND - PERCEPTIONS OF ICEBERGS IN 1912
MARITIME SAFETY INCIDENTS INVOLVING ICEBERGS OR WHITE STAR LINE
1873 - April 1, 1873 the White Star Liner ATLANTIC (3,700 tons) ran aground 15 nautical miles (nm) SW of
Halifax, Nova Scotia, having diverted there in deference to New York, because of heavy seas and low fuel state.
She eventually capsized to starboard, and inrushing seawater caused boilers to explode. 400 survivors, mostly
crewmen, all but 1 of the 200 children died. 547 deaths resulted, making it the worst maritime catastrophe on thehigh seas up until that time (1,700 people were lost when the steamer SULTANA sank on the Mississippi River about
seven miles north of Memphis on April 27, 1865).
1879 Guion steamer ARIZONA (at 5,750 tons, second largest ship in the world) left New York bound for Liverpoolin November 1879, with 509 people aboard. While crossing Newfoundland’s Grand Banks 250 nautical miles (nm)east of St. Johns, the ship hit an iceberg just after midnight while steaming at a speed of 18 knots (kts). She limped
into St. Johns 36 hours later, under her own power. She was later repaired in England.
1904 - On June 15th, an excursion steamboat, the GENERAL SLOCUM, caught fire going through Hell Gate on
New York’s East River, more than 1000 lives lost (worst maritime disaster prior to the TITANIC’s loss).
1907 – The White Star steamer SUEVIC (12,500 tons) was one of the first steamers fitted with watertight bulkheads.
She ran aground near Land’s End in Cornwall in March 1907. The forward end of the ship was left on the rocks andthe after 2/3 salvaged and towed back to Southampton! A new 212 feet long bow section is constructed in Belfast
and floated down to Southampton, where it was fitted to the remains of the ship. This was seen as a triumph fortechnology. The SUE VIC grounding and salvage leads most mariners to believe that modern steel steamers fittedwith watertight bulkheads are virtually unsinkable.
1907 - The Canadian Ship LAKE CHAMPLAIN strikes an iceberg, and damages bow. Other accounts say that she
sank, actual outcome unknown.

21909 - On January 22, the Steamer REPUBLIC (15,378 tons) collides with liner FLORIDA in fog about 170 miles
off the Massachusetts coast. The REPUBLIC sinks on the 24th while being towed, but thanks to wireless sets,
White Star Liner BALTIC comes to her rescue, and only 6 of the 1,650 passengers and crew are lost at sea. This
incident serves to reinforce the idea that wireless radio receivers can provide an acceptable margin of safety for eventhe most precarious maritime emergencies.
SHIPS PRESUMED LOST TO ICEBERGS OFF NEWFOUNDLAND’S GRAND BANKS
March 1841 - The steamer PRESIDENT crossing between New York and Liverpool, lost with 120 aboard.
March 1854 - The CITY OF GLASGOW left Liverpool bound for Philadelphia with 480 aboard, vanishes.
February 1856 - Ship PACIFIC bound for New York from Liverpool with 185 aboard.
May 1870 - The CITY OF BOSTON left Boston bound for Liverpool, with 191 aboard.
February 1892 - White Star liner NARONIC from Liverpool bound for New York
February 1896 - The steamer STATE OF GEORGIA, from Aberdeen for Boston
February 1899 - The steamer ALLEGHENY, from New York bound for Dover
February 1902 - the steamer HURONIAN, from Liverpool bound for St. Johns
All of these ships were presumed lost with all hands, and none of them were equipped with wireless communication.
Between February and May the Grand Banks are most infested with icebergs, and prior to 1901 no ships were fittedwith wireless communications. The ships that disappeared were assumed to have struck icebergs and sank. Up until
the time the TITANIC was lost (April 1912) avoidance of icebergs was dependent on visual watches from thevessel’s themselves, and darkness or foul weather could prove extremely dangerous. The common sighting
distance was one nautical mile, which usually afforded time to take evasive maneuvering. It was standard practicefor ships to halt when encountering ice fields at night and wait for daybreak before attempting any navigation
through such obstacles.
WHITE STAR LINE
White Star Line was formed in Liverpool in 1845, and established itself in the Australian trade by 1852, with one
ship. Went bankrupt in 1866-67; but assets and name purchased by Thomas Henry Ismay of Ismay, Imrie & Co. for£1000, who forms the Oceanic Steam Navigation Co. (OSNC) in 1869. OSNC contracted with Harland & Wolff
shipbuilders of Belfast to construct two new steamers for the transatlantic trade, the OCEANIC and ATLANTIC, of
3,700 tons each. These become the largest steamers then plying the seas. They began service to New York in 1871.
With six ships White Star Line plied the Atlantic and Asiatic routes. Harland & Wolff partners bought shares ofWhite Star and took seats on their board of directors, and vice versa.
White Star was absorbed by the International Mercantile Marine of J. P. Morgan in 1902-03. Morgan dies in 1913.
Thomas Ismay’ son J. Bruce Ismay served as President of IMM between 1904-1912. He is forced to resign from his
post in 1912 because of public humiliation concerning his surviving the TITANIC sinking. He lived in reclusion until
1937. White Star was sold to Royal Mail Line in 1926, which was then absorbed by Cunard Line in 1935, and all
White Star Line records were lost.
DESIGN OF TITANIC
The design team was originally headed up by Alexander Carlisle, Lord Pirie’s brother-in-law. He had designed the
OCEANIC in 1899, the first ship to surpass the massive GREAT EASTERN in size. He retired in June 1910, andleadership of the design team was assumed by Thomas Andrews, Pirie’s nephew. Prior to this Andrews had served
as Harland & Wolff’s Chief Draughtsman. Edward Wilding was Harland & Wolff’s Senior Naval Architect. After

J. David Rogers - Notes on loss of the RMS TITANIC3
TITANIC sank, it was Wilding who performed the admirable calculations concerning the net size of the opening thatsank the ship, about 12 square feet. After completing these remarkable studies Lord Pirie fired him.
TITANIC’s design size was 852.5 feet long by 92.5 feet wide. Height from keel to C Deck was 64'-9" (top to top).
C Deck was the highest which extended along the entire length of the ship. Design waterline was 34'-7" atamidships. The upper three decks (superstructure) were fitted with two expansion joints, immediately abaft Funnels
1 and 3. These joints could accommodate two feet of expansion/contraction.
TITANIC’S POWER PLANT
The TITANIC was powered by two sets of four-crank triple expansion reciprocating steam engines drove the wingpropellers (outboard shafts). Each engine had four inverted pistons with direct acting cylinders, fed by 215 psi input
steam pressure from the boilers. The high-pressure cylinder was 54 inches in diameter; the intermediate 84 inches
across, and the low pressure cylinder being 97 inches in diameter, with a piston stroke of 6 feet 3 inches. The wingpropellers were made of magnesium bronze, with 3 blades each and were 23-1/2 feet in diameter. The design shaft
horsepower (shp) was 15,000 at 75 rpm, and 17,000 shp at maximum turn (80 rpm).
The center shaft was powered by a Parsons Low Pressure Turbine, which ran off the exhaust steam from thereciprocating engines. It propelled a four-bladed magnesium bronze propeller, 16-1/2 feet in diameter. No
reversing mechanism was accommodated in the early Parson’s Turbines. The maximum shaft horsepower (shp) was
16,000 at 175 rpm. Total shp for all three engines was 50,000 for a design speed of 21 kts, but she was capable ofdeveloping 55,000 shp if operating all her boilers.
BOILERSSteam was provided by 24 double-ended and five single-ended boilers, arraigned to deliver a working pressure of
215 pounds per square inch (psi). The 29 boilers were distributed within 6 boiler rooms, separated by watertightbulkheads between adjacent coal bunkers. The boiler rooms were numbered aft to front (1 to 6). The 159 furnaces
were hand stoked, from either end on the double-ended boilers, fed from coal bunkers forward and aft of each boiler
room. The five single-ended boilers were confined to Boiler Room 1 and were intended to provide auxiliary power.
The two port boilers in Boiler Room 2 were intended to provide steam for the electric light engines. During typicaloperations about 1/5 of the boilers would be shut down for underway maintenance or fuel conservation. On
TITANIC’s maiden voyage all of the boilers were gradually brought on line and the shaft horsepower and ship speed
increased accordingly.
BILGE PUMP CAPACITY
Five ballast and bilge pumps were fitted to the ship’s amidships area, each capable of delivering 250 tons of water
per hour (or 2.23 cubic feet per second), and three bilge pumps were capable of sustaining 150 tons per hour. These
made for an aggregate capacity of 1,700 tons per hour of pump capacity, or 407,564 gallons per hour, sufficient tokeep pace with an maximum inflow rate of 15 cubic feet per second (which should theoretically have kept her afloat
for a week). However, three bilge pumps were distributed in the boiler rooms, two in the reciprocating engine roomand the other in the turbine engine room. There were no sluice valves incorporated into the bilge system, so nomeans of joining the pumps in series to allow water to be pumped from one compartment to another. The enormityof this oversight was appreciated in TITANIC’s post-failure assessments, which suggested that it took the ship 2 hrs
20 min to take on 16,000 tons of sea water. This back-calculates to approximately 12 ft2 of hull opening allowing
sea water to infiltrate the hull.
HULL DESIGNTITANIC utilized a 5'-3" double bottom throughout most of the hull, increasing to 6'-6" below the reciprocating
engine spaces. The annular space contained the water tanks for trimming the ship. This cellular structure wasreferred to as “The Tank Top”, and it provided a greater degree of structural integrity and stiffness for the overall
structure of the hull. Water in this bilge keel was also used to stabilize the ship in rolling seas. A 300 feet long and25-inch deep external bilge keel was also utilized amidships to reduce rolling (one of the first liners to employ thisadvance).

Construction of the Tank Top utilized 500,000 steel rivets, alone weighing 270 tons. This represented 1/6 of themore than 3,000,000 rivets used to construct the ship. The tank top also utilized three longitudinal divisions tocreate four longitudinal watertight compartments. The centerline division was 670 ft long, while those on either sideof the keel were 447 ft long.
The remainder of the ship was constructed using conventional frames with riveted hull plates. The FRAMES werespaced 3 feet apart, tapering to 2 feet in the bow and stern areas. The steel HULL PLATES were 6' x 30' x 1"
thick, each weighing 3 tons.
The TITANIC employed an old fashioned kingpost RUDDER, similar to a Spanish Galleon. It was of an ellipticalshape, made of cast steel in 6 pieces. The rudder was 78'-8" high and weighed 101 tons. It was woefully undersized
for a ship of this displacement.
SIZE AND DISPLACEMENTThe TITANIC was 852-1/2 feet long and up to 92.5 feet wide. At launching (May 31, 1911), she already displaced
24,000 tons. Her gross registry tonnage was 46,328 tons, with 21,831 net register tons (how much load she could
carry in addition to her dead weight displacement). She displaced 52, 310 tons when her draught was 34'-7", andup to 66,000 tons if fully loaded. Long tons (2240 pounds) were used to calculate displacements by Harland &Wolff (in contrast to our American system).
LIFEBOATSEnglish legal requirements for lifeboats were set by the 1894 Merchant Shipping Act, which only envisioned ships
up to 10,000 tons. The Regulations of the British Board of Trade were actually being reformulated in early 1912 toconsider the much larger vessels then plying the seas. White Star Line was legally bound to have sufficient lifeboats
for 960 people, but they actually provided space for 1,178. 3,560 cork life belts also supplied.
Harland & Wolff designer Alexander Carlisle originally envisioned 64 lifeboats, but the White Star management(Bruce Ismay) objected to the seemingly cluttered appearance of doubling up the lifeboats next to the Welin davits.
The purpose of using Welin Davits was to accommodate extra boats at each launch position. The number of boats
was downgraded to 40, then 32, and finally down to 20. The patented Welin Davits were supplied with sufficientrope to lower three boats each. The ship’s forward davits were always swung outboard with the lighter 40-man
cutters, used for harbor pilot liaison and man-overboard emergencies (referred as the “emergency cutters” by thevessel’s officers in post-failure testimony).
The ship carried 14 regular lifeboats. These main lifeboats were intended to have a passenger capacity of 65 each(910 people); the two crew cutters with 40 each (80 people) and the four Englehardt collapsible boats were designed
for 47 each (188 people); giving TITANIC a theoretical lifeboat capacity of 1,178 persons. Collapsibles A and B
were stowed on the roof of Officer’s Quarters while C and D rested on forward end of Officer’s Promenade.
TITANIC’S SISTER SHIPS
R.M.S. OLYMPIC preceded TITANIC by about 9 months, having been launched on October 20, 1910, andcommissioned in June 1911. OLYMPIC’s initial year of operation was dismal from a financial perspective, withcostly delays afforded by the September 1911 collision with HMS HAWKE and the February 1912 loss of her port
propeller, both incidents requiring major refit work in Belfast, causing her to miss 7 transatlantic trips. When she
departed New York on March 23, 1912 she was carrying 4,800 tons of additional coal for TITANIC (the English coal
strike was settled on April 6, 1912, but many weeks passed until recovery actually occurred). OLYMPIC began her
7th transatlantic trip from Southampton on April 3, 1912, 12 hours before TITANIC arrived at Southampton coming
down from Belfast.. OLYMPIC departed New York City on her return leg on Saturday morning April 13, 1912. She
was steaming 750 nautical miles (nm) from New York when she received TITANIC’s CQD in early morning hours
of April 15th.

J. David Rogers - Notes on loss of the RMS TITANIC5
The OLYMPIC served as a troop transport during World War I and was converted to an oil burner in 1919-20. She
served on until 1935, and was sold and broken up for scrap in 1937. She was known throughout her career as “Old
Reliable”, and her remarkable safety record after 1912 gave rise to legends about curses and good luck charms
aboard ships.
White Star announced their intent to construct a third ship of the OLYMPIC Class on Sept 1, 1911, to be named the
GIGANTIC. After TITANIC sank, White Star changed the name from GIGANTIC to BRITANNIC. Due to financial
difficulties associated with the TITANIC disaster, the BRITANNIC was not launched until two years later, inFebruary 1914. She was 889 ft long and 94 ft wide, with 48,158 [long] tons displacement. The First World War
erupted in August 1914 and BRITANNIC was completed in November 1915 as a hospital ship and commissioned in
the Royal Naval Reserve in December 1915. She made five voyages to the Mediterranean bringing back 15,000
wounded and sick. She struck mine in the Aegean Sea off Kea Island on November 21, 1916. The explosion caused
a secondary explosion of coal dust in several of her coal bunkers, hastening her demise. She took 50 minutes to sinkby the head, but with only 21 killed. 10 of the 35 White Star Line steamers were lost in combat during First World
War. White Star was given several German liners after the war as reparations.

COLLISION BETWEEN THE HAWKE AND THE OLYMPICThis incident was a important in the TITANIC legacy because the damage required cannibalization of parts from theincomplete TITANIC and the OLYMPIC missed three transatlantic voyages, costing the firm more than half theenormous liner’s original cost. The collision occurred on September 20, 1911, right at the beginning of
OLYMPIC’s fifth trans-Atlantic voyage to New York. She was sailing down the Southampton Channel towards
some shoals called “The Bramble”, where she had to execute an inverted “S turn” to cut southeasterly, down theSpithead Channel towards Portsmouth, thence across the English Channel to Cherbourg. OLYMPIC was underpilotage traveling 18 kts down Southampton Channel and slowed to 11 kts to execute the reverse turn at The
Bramble. She made a sweeping turn to starboard, showing her port side to HMS HAWKE (coming up the channel);then OLYMPIC’s pilot rang two blasts of her horn and reversed his turn, coming to port to bring her onto asoutheasterly heading, accelerating in the port-hand turn. By bringing her starboard side against the HAWKE’s portside, she was rendered to give way to the HAWKE, as priority was always to be given to the starboard ship (HAWKE
now located to starboard of OLYMPIC).
Believing they had right-of-way priority, and misunderstanding that OLYMPIC was turning to proceed parallel totheir track, HAWKE waited too long before taking evasive action, and her rudder jammed when she attempted a
sharp port turn to clear OLYMPIC’s stern. The force of suction pulled the HAWKE into the OLYMPIC’s starboard
side near her stern. The British Admiralty hired renowned American naval architect Rear Admiral Donald W.
Taylor to be their expert witness on the effects of suction created by large displacement ships and prevailed in the
succeeding litigation.
DAMAGE TO OLYMPICOLYMPIC spent two weeks in Southampton having temporary repairs effected to make her seaworthy. She left
Southampton on October 4, 1911, and proceeded at 12.5 kts. HAWKE’s bow rammed OLYMPIC about 86 feetforward of her stern post, inverted triangular hole 14 feet wide at top, extending down from D Deck 15 feet, and 8feet into the OLYMPIC. HAWKE’s ram was beneath water and shaped like an inverted pear, it punctured hull
between G and Orlop Decks. 18 feet of the starboard propeller bossing was damaged and all three blades of the
starboard propeller. Hawke’s concrete-filled ram was recovered from inside the OLYMPIC in the drydock at
Belfast.
REPAIR OF OLYMPIC
Placing the OLYMPIC in drydock meant displacing the TITANIC, and redirecting the yard’s work force to making
repairs to OLYMPIC as soon as practicable. Repair work entailed part of OLYMPIC’s starboard crank shaft, which
was strained and out-of-true. Two of the four shaft sections serving the starboard propeller were damaged. The

6
aftermost section was externally accessible, but remainder not, so her hull plates had to be removed. In order torestore her in a timely fashion, they cannibalized the TITANIC’s starboard propeller blades and propeller shaft. The
repairs took 6-1/2 weeks to complete, pushing back TITANIC’s scheduled completion 3 weeks, to April 10, 1912.
But the collision cost White Star dearly, as OLYMPIC was unable to return to service until November 29, 1911,
having missed three round-trip transatlantic voyages, and the revenue generated thereby. White Star lost £250,000
pounds Sterling, half the original building cost, and the ship was only insured for 2/3 of the building cost.
Postscript: The British cruiser HMS HAWKE sunk by U-9 three years later in North Sea on Oct 15, 1914, with lossof 550 souls.
OLYMPIC LOSES HER PORT WING PROPELLER BLADESOLYMPIC subsequently lost her port propeller blades on a submerged wreck on the Grand Banks off Newfoundland,
about 750 nautical miles (nm) from New York, on February 24, 1912. This repair took a week, and caused her tocancel her scheduled transatlantic trip of March 6, 1912. Once again, Harland & Wolff had to haul TITANIC out of
the Thompson Graving Dock in Belfast to scavenge a new prop for the OLYMPIC. The last photo of the two sister
ships taken together was on March 6, 1912 next to Thompson Graving Dock in Belfast.

DIFFERENCES IN APPEARANCE BETWEEN OLYMPIC AND TITANIC
Near the last moment of fitting out (in mid-March 1912) IMM Chairman J. Bruce Ismay asked that the forward
portion of the A Deck promenade be fitted with screened sliding windows. This section was 192 feet long. In
addition, the enclosed B Deck of TITANIC was also longer than OLYMPIC, with a less uniform pattern of windows.
Front names on both ships were in burnished gold on black hulls, hard to see in photographs. Virtually all interior
photos of the TITANIC were actually imaged aboard the OLYMPIC.
DESIGNATION AS R.M.S. TITANIC
Because of her superior speed, TITANIC was designated by the British government as one of 13 transatlantic
steamers which carried the Royal Mail. She was, therefore, afforded the prestigious preamble R.M.S., for “Royal
Mailer Steamer”. This designation meant she was under contract to transport mail from the European continentacross the Atlantic Ocean, to the United States and Canada. During her maiden voyage she was carrying over 3500
bags, containing more than 500,000 pieces of mail.
TITANIC’S SEA TRIALS
Performed in Belfast Lough on Tuesday April 2, 1912, over a period of 12 hours. The ship averaged 18 kts for a 2
hour run, with bursts up to 21 kts. Her Turning Circle was determined to be 3,850 feet with a forward motion of
2,100 feet. Emergency stop from 20 kts took 850 yards (unloaded). Emergency stop from 22.5 kts would require
a little over 1,000 yards (half-mile). During her 570 nautical miles (nm) run to Southampton, she briefly reached23.5 kts (but, was not loaded) By comparison, OLYMPIC reached 22.75 kts at 78 rpm of her outboard screws.
TITANIC’S SAILING SCHEDULEWhite Star wanted to run a 3-week rhythm with their two leviathans, OLYMPIC and TITANIC. Each ship was todepart Southampton every 3rd Wednesday (picking up passengers in Cherbourg, France and emigrants in
Queenstown, Ireland), and reaching New York the following Wednesday morning early. The ships were thencoaled up in New York during a 3-1/2 day layover, departing New York early Saturday morning. The return leg
made landfall at Plymouth, crossing to Cherbourg, then back to Southampton, where they were coaled for the next
trip. Queenstown [called Cobb today] was an emigrant loading point, only frequented on outbound legs.
CREW OF TITANIC

J. David Rogers - Notes on loss of the RMS TITANIC

7
Edward John Smith, b. 1850 at Hanley in Staffordshire. He left school at age 13 in 1863 to go to sea, joining
White Star Line as a 6th Officer in 1880 at age 30. He rose rapidly to Captain by 1887. He was given command of
TITANIC on April 1, 1912, coming from her sister ship, the OLYMPIC. He had received the Admiralty’s Transport
Medal for captaining troop ships during the Boer War and the Royal Navy Reserve Decoration. He was also a
Commander in the Royal Naval Reserve (RNR), and therefore allowed to fly the blue RNR ensign from the vessels
he commanded. A very visual status symbol, this added to his status as “the millionaire’s captain”. In 1904 Smith
became Commodore of the White Star fleet (their most senior steamer captain). In 1907 he was given command of
S.S. ADRIATIC, the first turbine-powered ship in the White Star fleet. The ADRIATIC ran aground in New York’s
Ambrose Channel on November 4, 1909. He was also given command of the OLYMPIC when she wascommissioned on May 31, 1911.
Smith was commanding OLYMPIC when she collided with HMS Hawke in September 1911. At the time of
TITANIC’s sailing he was the world’s highest paid seaman, at £1,250 per year, with £200 annual bonus for avoiding
any collisions, half of which was customarily divided between the senior officers (the three senior officers rotatedthe con of the ship’s bridge in 4 hour shifts). He was quoted in the New York TIMES in May 1907, whilecommanding the SS ADRIATIC:
Quote: “I will say that I cannot imagine any condition that would cause a ship to founder.....Modern shipbuilding
has gone beyond that.
Henry Wilde signed on as Chief Officer of TITANIC at 6 AM on sailing day, Wed April 10th. He had been
detached from the OLYMPIC on April 3rd, and granted leave until the 10th, by request of Captain Smith. His
acquisition bumped Murdoch down to First Officer and Lightoller to Second Officer. Second Officer Blair left
the ship on Tuesday April 9th, but not before stowing the lookout’s binoculars in his cabin without having informed
Lightoller of their whereabouts, in the Second Officer’s cabin. This oversight was to have enormous repercussions.
Only Wilde, Murdoch or Lightoller could command the watch. Their sailing schedule was 4 hrs on the con withan intervening 8 hrs off. Of the senior officers, only Captain Smith and Charles Lightoller held Extra Master’sCertificates, while Wilde and Murdoch held Ordinary Master’s Certificates. An Ordinary Master’s certificate was
required to have active command of the ship.

CREW
The White Star crew for TITANIC numbered 799. 500 of these looked after the passengers, 325 cared for theengines and power plants, while only 66 were actually responsible for sailing the ship. The remaining 8 were theband members, assigned to the second class passenger list.
PASSENGERS
The OLYMPIC and TITANIC were designed to accommodate 735 First Class, 674 Second Class and 1,026 Third
Class (or steerage) passengers, for a total of 2,435. With her crew of 900, the ship was certified to sail with 3,300
people. During her maiden voyage TITANIC was carrying 329 First Class, 285 Second Class and 710 Third Class
passengers, for a total count of 1,324 passengers. This was about 54% of TITANIC’s maximum capacity. Total
passengers and crew embarked for the Maiden Voyage was 2,223 people.
Meals were served:

Breakfast 8:30 to 10:30 AM
Dinner (lunch) 1:00 to 2:30 PM
Tea (dinner) 6:00 to 7:30 PM

NAVIGATION DURING LAST VOYAGE

J. David Rogers - Notes on loss of the RMS TITANIC

8
Like other westbound liners, TITANIC took the OUTWARD SOUTHERN TRACK across the north Atlantic Ocean,an established sea lane which had been used by westbound ships between January 15th and August 14th of each year,
since 1899. Exceptions were 1903, 1904, and 1905, when westbound vessels crossed the 47th meridian about 60
nautical miles (nm) further south, because of sea ice. This was a great circle route emanating from FASTNETROCK on the southwest tip of Ireland to the TURNING POINT, along a compass track of S 62o W, or 242o true.
The TURNING POINT was located at 42o N latitude and 47o W longitude . From this point, the route shifted
westward, towards the Nantucket Shoal light vessel off New York, on a track of S 86o W, or 266o true.
Before leaving the bridge for dinner with the George Wideners and John Thayers on Sunday evening April 14th,
Captain Smith left instructions in the Night Order Book for the turn to be made at 5:50 PM, 30 minutes later thanwhen due. This delay was because of the ice sightings TITANIC had received from other vessels taking the same
track during the previous 24 hours. At a speed of 22 kts, this would have taken TITANIC about 11 nautical miles(nm) further along the 242o course, resulting in a westward track towards New York about 4 miles further south of
the standard track. According to Fourth Officer Boxall, this turn was made at 5:50 PM, as ordered. Plotting thedescribed track lines assuming a turning point 11 nm pass the traditional turning point brings the ship’s track to thecollision and sinking positions established in 1985 by the Woods Hole expedition that eventually discovered thewreckage.
Most investigators have assumed the delayed turn was ascribable to the ice warnings received that afternoon, which
lay across their proposed course. The new course would have taken them somewhat southward and to the west of
the ice reported by White Star’s BALTIC and south of that reported by Cunard’s CARONIA, earlier in the day.
Plotting their respective reports would suggest an ice field up to 78 miles across had been reported directly in theirpath. A major omission in Captain Smith’s thought processes may have been forgetting to account for the ice pack’s
southward drift, which was about 1 mph. That could have brought the ice pack 20+ miles further south-southeast
than the positions reported by BALTIC and CARONIA and likely plotted on TITANIC’s navigational charts.
TITANIC’S INCREASING SPEED
The TITANIC increased speed each day, bringing more and more boilers online, and extinguishing the fire that brokeout in Coal Bunker 10. By Sunday April 14th the last three main boilers of 24 were brought online. TITANIC’s
speed increased to about 22.5 kts on PM run April 14th. The last five boilers were usually reserved for auxiliary
power, but it is believed Bruce Ismay ordered that these be brought online the following day (Monday) for a highspeed run into New York. This would have brought TITANIC into New York Harbor early Tuesday evening insteadof Wednesday morning, and likely made something of a splash in the New York newspapers, gaining publicity forthe faltering White Star line, which was in deep financial distress.
From Noon Thursday April 11th to Noon Friday April 12th included 2 hr layover at Queenstown, Ireland. The shipran 464 nautical miles (nm), with her wing screws turning at 70 rpm. From Noon Friday to Noon Saturday the shipcovered ran 519 nautical miles (nm) with her wing screws turning 72 rpm. From Noon Saturday to Noon Sunday
the ship covered 546 nautical miles (nm) at 75 rpm (only 2 nautical miles short of OLYMPIC’s record 24 hr run).
Remember, going west, the ship’s clocks were turned backward each day, so the average speeds are not quite as fast
as the figures suggest.
On her last day, the TITANIC supposedly gained 260 nautical miles (nm) between 12 Noon and 11:40 PM collision,
for an average speed of 21.75 kts; but the clock would have been turned back 1 hour at Midnight, so actual speed
was closer to 22.25 kts. On Monday April 15th the remaining five auxiliary boilers were to have been brought
online, because the ship had precious little coal to spare on her maiden voyage to New York.
COAL SITUATIONThe capacity of TITANIC’s 11 coal bunkers was 8,000 tons. The bunkers ran from the Tank Top to the underside of
F Deck. The bunkers were numbered from amidships forward. With the exception of the area forward of Bunker 11,
these bunkers were arraigned in back-to-back pairs. Watertight bulkheads split all of the coal bunkers.

J. David Rogers - Notes on loss of the RMS TITANIC9
TITANIC left Belfast with 1,880 tons of coal, enough for 3 days steaming It was intended to collect another 5,500
tons of coal left in Portsmouth by the OLYMPIC (she actually contributed 4,427 tons). Coaling was done by handlabor from small coalers, or lighters, rowed up against the ship’s sides. This was a holdover from older days withsmaller ships. More sophisticated coaling procedures were developed soon thereafter.
FIRE IN COAL BUNKER 10
Shortly after completing her April 2nd sea trials off Belfast, TITANIC developed a spontaneous combustion fire of
the coal stored in the starboard side of Bunker 10. Bunker 10 was situated at the after end of Boiler Room 6, andjust ahead of Bulkhead No. 5. The fire began in Belfast, and was extinguished by gradually emptying thecontents and stoking the adjacent boilers with this material (which was standard procedure). By Saturday morning
April 13th, the bunker was excavated of its cargo, and the fire thereby extinguished. The fire may have made thehull plates more brittle in this area, but these plates have never been recovered for testing. Critical buckling of hullplate laps extending 2 feet into this bunker allowed seawater to infiltrate Boiler Room 5, sealing TITANIC’s ultimate
fate. That two feet made all the difference.
UNUSUAL WEATHER CONDITIONS
1911-12 was the mildest winter in the north area for over 30 years. More icebergs, ice floes and field ice drifted
further south than reported in previous 30 years. The icebergs were brought southward along COLD LABRADOR
CURRENT, and then swept NORTHEASTWARD along the GULF STREAM. The source of the ice floes
encountered by TITANIC was in Disko Bay, GREENLAND. Bergs cleaving off from this locale can take three
years to reach the Grand Banks off Newfoundland.
Six separate ice warnings were received by the TITANIC on Sunday April 14th. The descriptors used in the wirelessreports included: Icebergs; large masses, more than 200 feet across; Growlers: smaller icebergs; Ice Floes: sea ice
broken up but moving together as one broken patch; Sea Ice: one uninterrupted mass of ice. Ice packs and floes
normally drift southward between ¼ and 1-3/4 nautical miles per hour (knots).
TITANIC entered the cold water of the Labrador Current beginning around 5:30 PM Sunday. By 7:30 PM the sea
water temperature had dropped 10 degrees F, and was measured to be about 33o F, falling to 32o. At 9 PM theofficers on watch became concerned about freezing of the fresh water supply in the ship’s tank top and amidships
bilges, the ocean temperature had dropped to 28o F (which is an unusual circumstance). The iceberg TITANIC
struck was described as a twin-peaked mass, more than 200 feet high, with a red-ochre scratch line at the water level,from scrapping the TITANIC’s anti-fouling paint. She was also described as being “black ice”, suggestive of having
turned and rotated in the water as she melted. Icebergs containing “black ice” can be very stinky, due to rottingorganic inclusions.
Sunday evening saw flat calm seas, such as had never been seen in the North Atlantic. It was also was a moonlessnight (new moon). A slight breeze began to blow during the hour just before dawn on Monday April 15th. Breezes
and wave swells are acutely common on the high seas. The absence of waves against the iceberg accounted for the
failure to spot it inside of 2,000 yards (one nautical mile), which was the normal sighting distance on a moonless sea.
Waves lapping against the iceberg would be observable, even on a dark night, due to the customary
phosphorescence caused by turbulence and wave splash. In this respect, the lookouts would have been greatly
aided by binoculars, so as to keep their eyes from watering. But, without waves splashing against the bergs, theywould have been virtually invisible until a very close distance. Steaming at 22+ kts in such an area with such a large
unwieldy ship was somewhat reckless in retrospect, especially when compared to the other steamers in the area, who
exercised considerably increased caution.
LOOKOUTS WITHOUT BINOCULARS
Second Officer David Blair came aboard at Belfast, and sailed with TITANIC to Southampton. He was charged
with stowage of the binoculars for the ship’s lookouts. The binoculars were labeled “Second Officer, Titanic”.
Blair locked all five pairs of binoculars in his cabin on Tuesday April 9th, which was inherited by Charles
Lightoller the following morning. Blair was dismissed at Southampton and reassigned a berth on another ship toaccommodate Henry Wilde as the new Chief Officer (which bumped William Murdoch and Charles Lightoller

down one rank). The ship was steaming at a speed between 22.25 and 22.5 kts during last evening with considerable
wind chill. The lookout’s eyes would have to have watered up pretty quickly. The wind chill factor would havebeen approximately –27o F, bringing the ambient air temperature down from 35o F to about 8o F. This would havecaused the lookout’s eyes to water after only a few painful seconds. Binoculars would have helped protect theireyes from watering, as well as made their vigilance more effective.
SIGHTING OF ICEBERG
The iceberg which TITANIC struck was initially sighted by lookout Frederick Fleet from the forward Crows Nest,
situated 95 feet above the water line. He sounded three strokes on the Crow’s Nest bell, signifying an object wasdead ahead of the ship, at 11:39 PM (ship’s time) at distance of about 500 yards. At a sped of 22.5 kts, this gave theship about 40 seconds to react. Other icebergs had previously been reported during the watch, but not directly inship’s path. Murdoch should have taken these sightings more seriously. Fleet rang the bridge on his phone: Are
you there? Moody: Yes, what do you see? Fleet: Iceberg right ahead! Moody: Thank you. [to First Officer
Murdoch] Iceberg right ahead! Murdoch to helmsman: Hard a-starboard!
ATTEMPTED EVASIVE ACTIONFirst Officer Murdoch commanded the watch, assisted by 6th Officer Moody. Quartermaster Robert Hitchens wasat the ship’s helm. Murdoch ordered “hard a-starboard”, meaning turning the ship’s wheel to the right, in orderto turn the ship to the left. It was a hold over command from sailing days, and the use of these terms were discarded
in 1928. Today we would say “left full rudder”. The rear of the ship would swing outward in opposite direction,
like driving a forklift with rear steerage. The rudder is the one control apparatus on the ship’s bridge that was
directly connected to the maneuvering room, and there should have been no lag in response. It was a power assisted
rudder. Murdoch’s intention was to swerve around the iceberg by going hard-a-starboard followed by hard-a-port.
The ship needed 850 yards to stop from 20 kts, and about 1000+ yards to stop from 22.5 kts (she was now almost
fully loaded). Murdoch found himself without adequate separation to effect the prescribed evasive maneuver.
Murdoch then ordered “FULL ASTERN”, taking the bridge telegraph through “ALL AHEAD STOP” first. He thenrang the bell button warning of watertight door shut-down for 10 seconds, then pulled the switch to close thewatertight bulkhead doors electrically. The doors were closed just AFTER striking the iceberg. All of these actions
were standard specified procedures for avoiding an imminent collision.
WHY THE SHIP DID NOT RESPOND QUICKLY
Unlike the rudder, control of the ship’s engines was via the telegraph, connected to the engine rooms. An engine
room telegraph works like the actual engine controls, and in order to switch power from FLANK to FULL ASTERN,
the operator would first have to go through ALL AHEAD STOP, a time consuming process, as described below.
On the outboard reciprocating engines, the engineers would have to close off the main steam valves to each engine,by bleeding off the steam feed down to zero pressure, which would then back up steam in the boilers. In order toavoid shock wave in the boilers, this steam has to be blown up the funnels. The entire time TITANIC was loading
her lifeboats, there was so much excess steam it was being blown up the funnels. Although choking off the steam
feed shuts down the mechanical driving force to the engines, the props would continue to spin with forward rotation
because of the ship’s forward momentum.
On the triple expansion reciprocating engines connected to the ship’s wing props the engineers would have been
forced to bring these shafts to a stop, or have a clutch. Once the shaft has stopped turning forward, the shaft isreversed by opening the steam valve to the reverse side of the engines. In those days manual adjustments wererequired to reverse motion of the steam cylinders that move the valving between the pistons (two valves, one pushes
down and the other pushes up). Nevertheless, one big advantage of reciprocating engines is that they offer fullhorsepower in reverse.
The centerline turbine is completely different. Today’s turbines include separate blades for reverse motion attachedto the same prop shaft, using a different steam inlet (modern turbines generally allow for about 15% of the power inreverse). The TITANIC’s central propeller was turbine powered, but without any ability to reverse. Unfortunately,
it was this screw which also had the greatest influence on the rudder, and hence, maneuvering.

J. David Rogers - Notes on loss of the RMS TITANIC11

In modern turbine-powered shafts, a brake must be applied to slow down the forward spin of the shaft. After
shutting down forward power, the engineers in the engine room would then turn on the reverse valves to serve as abreak, slowing down the forward motion of the screws. The screws would have to come to a complete stop before
reversing, and then begin turning in the opposite direction before actual deceleration would commence.
“FULL ASTERN” WAS THE WRONG CALL
The force on the rudder is proportional to the volume of water pushing against it. The rudder serves to flare thestern in one direction or the other; using rearward steering like a forklift. In order to turn the ship to port, the port
outboard shaft would be shifted to ALL AHEAD ASTERN while the starboard outboard prop would be advanced to
ALL AHEAD FULL, with the central shaft ALL AHEAD FULL, to push as much water against the rudder as
possible, so as to pull the ship’s stern to the right. The rear end of the ship would move in the direction opposite
the turn. The bow doesn’t move per se, just the stern. This is a difficult concept for lay people to grasp who havenot actually steered large ships.
WHAT ACTUALLY HAPPENED
Robert Hitchens later testified that he pulled the ship’s wheel full to starboard, turning the rudder full tilt to port,
but the centerline (turbine powered) propeller pushing against the rudder was being shut down. The ship did notseem to respond to the rudder correction. 30 seconds passed before the ship even appeared to move, veering 2
compass points, or about 22.5 degrees to port when she struck the iceberg with a glancing blow. Contact began
about 50 feet behind the bow on the starboard side, extending about 180 feet, to Boiler Room 5's forward coal
bunker (Bunker No. 9). Contact with the berg lasted about 6 to 10 seconds. The time was 11:40 PM (ship’s time).
The maneuver was later reenacted with the OLYMPIC and it was determined that 37 seconds were required for the
ship’s bow to move 2 compass points to port at a speed of 22 kts, which would equate to 466 yards of forward
travel. This agrees with the testimony of Quartermaster Hitchins. This was how the estimate of “500 yards
distance” to the iceberg was deduced, after the fact.
The ship eventually stopped and began moving astern, then came again to a complete stop, then half speed ahead (toreduce the forward momentum) before shutting down to appraise their damage. The men in Boiler Room 6 wereable to scramble to safety as sea water rushed into the compartment.
TITANIC was designed to withstand flooding of its first 4 compartments, because these forward-most compartments
were small, having been designed to isolate damage in a bow collision. She actually had an additional bow
compartment fitted as compared to her sister ship OLYMPIC. Had TITANIC rammed straight into the iceberg she
would have easily survived, but this would have killed about 56 firemen berthed in the forward block of F Deck andit was not the prescribed avoidance procedure. Extreme maneuvering measures were always to be taken to avoid
collisions because it was hoped such measures would save the most lives.
WATER ENTRY
The worst hull plate buckling appears to have occurred at a position about 10 feet above the keel, or about 4-2/3 feetabove the tank top in Boiler Room 6. The hull plates were buckled at the rivet laps where the iceberg rubbed against
the segmented steel hull. Inspection revealed that seawater was observed entering the fore peak, No. 1 hold, No. 2
hold, No. 3 hold, Boiler Room 6, and Coal Bunker 9, just abaft Watertight Bulkhead 5, allowing water into Boiler
Room 5 approximately 25 minutes later. The damage extended over a length of approximately 180 feet, not the 300
feet commonly reported. Water entered Boiler Room 6 about 2 feet above the stokehold plates, but only at theafter end of the compartment. In Boiler Room 5 the separation only extended two feet into the forward coal bunker,
with water pouring in at the rate of “an ordinary fire hose”. At the time of the collision this bunker had no coal in it.
There was no indication of hull damage or leakage abaft of Boiler Room 5. Boiler Room 6 was evacuated almost
immediately. Within 10 minutes (11:50 PM local time) water had risen 8 feet in Boiler Room 6 and as much as 14
feet above the forward keel in the forward holds.

J. David Rogers - Notes on loss of the RMS TITANIC

12Around Midnight Captain Smith and Harland & Wolff Chief Engineer Thomas Andrews (who made the maiden
voyage to observe the ship’s performance) made a joint inspection of the damage. They observed mail bags (theywere carrying close to 5,000) floating 24 feet above keel level, indicating a leak of sizable proportion. Andrews
gave Captain Smith 1 to 1-1/2 hours, possibly two hours to go before the ship would founder. Smith seemedcompletely shocked by this information and became increasingly distant as the night wore on. Such detachment is acommon manifestation of emotional shock.
By 12:05 AM the floor of the squash court forward on F Deck was awash, 32 feet above keel level, and water began
entering Boiler Room 5, from Coal Bunker 9. By 12:40 AM the accumulating water likely built up to the height of
the watertight bulkhead at the level of E Deck. Then it would have begun to spill over, into the next adjacentcompartment (this spillage could have been delayed by proper counter flooding, discussed next).
FAILURE TO APPRECIATE COUNTER-FLOODING
If the watertight bulkheads between the boiler rooms had been carried upward to the Main, or Shelter Deck(officially referred to as “C Deck” on the ship’s plans), instead of the top of F Deck, the ship would have remained
floating. This oversight became apparent during Edward Wilding’s forensic assessment in the late spring of 1912.
The OLYMPIC was immediately retrofitted to correct this shortcoming and humanity witnessed the birth of thewatertight compartment, as opposed to the older watertight bulkheads employed up to that time.
This spilling over of intruding sea water over the forward bulkheads was exacerbated by the deepening head-ward
list of the ship, which increased the volume of water that could pour over each bulkhead. In this respect they would
have been better off leaving the watertight doors open and allowing sea water to enter the boiler rooms and engine
room. By spreading the water aft, the head-ward tilt would have been reduced, and the intake of water thereby
reduced, keeping the bow as high as possible. This would not have saved the ship, but could have prolonged its
sinking by as much as 2 to 4 hours. That may not seem significant, but keep in mind that the S.S. CARPATHIA
arrived on scene at 4 AM, just 1 hour and 40 minutes after the TITANIC sank.
The practice of counter-flooding for damage control was not appreciated or taught prior to the TITANIC’s untimely
demise. It became commonplace practice among the world’s navies immediately thereafter, especially during theFirst World War (1914-18). When the American battleships were attacked at Pearl Harbor in December 1941, all of
the junior officers standing watch that morning correctly applied counter-flooding to prevent their ships from
capsizing, after receiving enormous damage form Japanese torpedoes. The only ships which capsized were the
OKLAHOMA and the UTAH. The OKLAHOMA was unable to counter-flood because the inspection ports on herbilges had been opened for an inspection expected the following day. The UTAH was an old battleship that had
been converted to a target ship. She carried a skeleton crew and lacked modern damage control systems. She was
hit almost simultaneously by two torpedoes amidships on her port side. She quickly lost electrical power so could
not employ pumps to counter-flood. Lessons learned in the loss of TITANIC saved thousands of lives in the years
that followed.
WIRELESS COMMUNICATIONS
The wireless (radio) communications transmitter and receiver was invented by Italian Guglielmo Marconi shortly
before the turn of the 20th Century. Steamers began carrying wireless sets in July 1901, beginning with Cunard’s
LUCIANA. The Allen Line followed in 1902, and by 1904 most transatlantic ships were fitted with wireless sets,
operated under license by employees of the Marconi Company. This included the steamers of the White Star Line.
The guaranteed range of the Marconi set was 350 miles, but this increased greatly at night. The Marconi systemused aerials strung between the TITANIC’s two mainmasts, about 205 feet above the waterline. The wireless shack
was located at the after end of the officer’s house, behind the navigation bridge (on the Boat Deck level).
The bulk of a Marconi wireless operator’s earnings came from tips, provided by wealthy travelers. The minimum
cost of any message was $3 for 10 words. Sending wireless messages from a steamer at sea became a mark ofprestige and wealthy passengers fell over themselves to send messages. Messages could not be sent to the UnitedStates until the vessels came within range of the Cape Race, Newfoundland transmitter. That range was about 350
nautical miles (nm) during daylight and something close to 600 nautical miles (nm) at night. In the interim,
messages could be routed across the ocean from one transiting ship to another, and this is how weather and

navigational advisories were routinely passed between vessels. Most of the ship’s masters working the northAtlantic sea lanes knew one another by name, and virtually everyone knew TITANIC’s Captain E.J. Smith, who had
commanded ships on the North Atlantic sea lanes since 1887.
The TITANIC’s wireless transmitter broke down at 11 PM Friday evening April 12th, and was restored to operation
around 5 AM Saturday April 13th.

CQD/SOS MESSAGES SENT BY TITANIC
Fourth Officer Boxall was ordered to fix the ship’s position after the collision with the iceberg, using deadreckoning based on Second Officer Lightoller’s last fix at 7:30 PM. Unfortunately, Lightoller had made anavigational error the previous day, which was carried over into Sunday. Boxall calculated 41o 46' N and 50o 14' W.
The actual position appears to have been 49o 55’ W. In this area each minute of latitude equates to about 1,520
yards, so an error of 19 minutes longitude equaled 14.4 nautical miles. This was the erroneous position theyreported in all of their distress calls. The times referred to here are the TITANIC’s local ship time, which at thisposition (50oW longitude) was 1 hour, 50 minutes ahead of Eastern Standard Time in New York and Boston.
At 12:15 AM on Monday April 15th the first CQD message was broadcast from the wireless room, giving
coordinates 41o 44' or 41o 46' N and 50o 24' W. TITANIC’s call sign was MGY. CQ meant “All Stations”, and D
meant “Danger”. Later they also broadcast “SOS”, a simple distress code which meant “Save Our Souls”. It had

14
been introduced in 1908. Boxall’s amended position was received at Cape Race, Newfoundland at 12:25 PM The
French ship LA PROVINCE and the Canadian ship MOUNT TEMPLE acknowledge TITANIC’s first transmissions.
The ship RAPPAHANNOCK had just passed the TITANIC heading in the opposite direction and was only 15 miles
east of accident, but she was nursing a damaged rudder and had no wireless set.
An unidentified schooner was reportedly seen by the TITANIC lifeboats, the CALIFORNIAN and the MT TEMPLE.
This is now believed to have been the Norwegian SAMPSON, 506 Gross Registry Tons, 148 feet long, reported to
be about 8 to 13 miles distant during TITANIC’s sinking; according to a deathbed confession of its first officer in
1962 (described later). .
Wireless operator on the CALIFORNIAN (Cyril Evans) turned off his wireless set at 11:20 PM TITANIC time
(11:30 PM on CALIFORNIAN], 35 minutes before the first distress call.
SIGNAL SOCKET FLARES
Fourth Officer Boxall was ordered by Captain Smith to fore the socket flares. He was assisted by Quartermaster
George Rowe and begin firing SIGNAL SOCKETS from the starboard side of the navigation bridge. They could
see the CALIFORNIAN’s red and green navigation lights; later switching to a red light with two white mastheadlights (indicating a turn away, to starboard). Rowe and Boxall also tried to raise the mystery ship with a hand held
Morse signal lamp. The officers standing watch aboard the CALIFORNIAN simultaneously attempted to signal
TITANIC with a Morse Lamp. The effective range of a hand-held Morse Lamp was only 4 to 5 miles, so this wasineffective.
The socket signals falres were launched from mortars on the bridge wings. They fired white missiles 800 feet into
the air, exploding into 12 slowly falling white stars. Boxall launched 8 rockets at 5-minute intervals, beginning at
12:45 AM, as the first lifeboat was launched, and finishing at 1:20 AM, as Boats 9 and 10 took to the water.
There were no uniform international procedures for distress signals, however, there was an established custom andpractice of firing rockets at regular intervals to indicate an emergency. White rockets were recommended. This
became a contenious uissue for the Captain Lord of the CALIFORNIAN the rest of his life, though he was asleep
during most of this period.
The CALIFORNIAN placed her original stop position at 42o 5' N 50o 7' W, which would have initially been about
13.5 miles NW of TITANIC’s impact with the iceberg. With a SSE drift of 1 nautical miles (nm)/hr, she should have
moved about 1.7 nautical miles (nm) closer, making her about 11.8 miles distant when the TITANIC stopped (ifCaptain Lord’s position was absolutely accurate). Considerable testimony from watch standers on TITANIC,CALIFORNIAN and MT TEMPLE suggest CALIFORNIAN was drifting within 8 to 15 miles of TITANIC when she
sank. TITANIC struck the iceberg at 41o 47'N and 49o 55' W, but both vessels appear to have initially drifted SSEwith clockwise rotation, then SSW, with the prevailing current. Neither ship dropped anchors.
LOADING OF TITANIC’S LIFEBOATS
45 minutes after colliding with the iceberg, Captain Smith gives the order to load the lifeboats with “women andchildren” [first], at 12:25 AM. TITANIC had 14 special purpose lifeboats, designed to hold 65 people each. These
had been load tested by Harland & Wolff, but the successful operation not recounted to the ship’s officers. These
lifeboats were 30 feet long, much larger than standard lifeboats of that period. She also carried two emergency
cutters, capable of holding 40 people each, and 4 Englehardt collapsible lifeboats.
First Officer Murdoch and Fifth Officer Lowe were assigned to supervise loading of lifeboats on the starboard side;
while Second Officer Lightoller and Sixth Officer Moody were ordered to supervise loading on the port side. Theyboth began at amidships and worked their way forward.
It took 20 minutes to get the first boat loaded and into the water, Boat 7 was lowered away on the starboard
amidships at 12:45 AM. The first lifeboat launched from the Port side was Boat 6 at 12:55 AM, with 28 aboard.
Boat 5 lowered away at 12:55 from starboard side with 41 people and Third Officer Harold Pitman. Boats 5 and 7

15
later joined together. Pitman was ordered by Captain Smith to row towards the mast light on the north horizon[thought to be the CALIFORNIAN], which appeared to be about 5 miles distant, 2 points (22.5 degrees off the
starboard bow (it is more likely that she was about 11 miles distant).
Cutter Boat 1 launches from forward starboard at 1:10 AM with only 12 people (capacity of 40). Boat 8 was
lowered from the port side around the same time (1:10 AM) under Chief Officer Wilde’s supervision, aided byLightoller. 39 aboard, including 35 females. By 1:10 PM, 10 lifeboats had been lowered and 10 remained aboard.
Starboard Boat 9 was next lowered at 1:20 AM with 56 aboard, including 42 women. Port Boat 10 lowered at 1:20
AM with 41 women and 7 children aboard.
Those gathered topside could see the masthead lights of the CALIFORNIAN and most were confident this nearby
ship would be summoned to come to their aid. This knowledge and the seemingly slow descent of the bow
persuaded many first and second class passengers to refrain from being loaded aboard the lifeboats.
At 1:25 AM Boat 11 lowered from starboard side with 63 aboard. The ship’s bilge pumps discharged into thelifeboat as it was being loaded, drenching its occupants. At 1:25 AM portside Boat 12 lowered with 42 aboard. At
1:30 AM Chief Officer Wilde orders Fifth Officer Lowe to take command of Boat 14, with 63 aboard. At 1:35 AM
the last of the regular lifeboats on starboard side was lowered. Boat 13 carried 59 women and 9 men (including 5
crewmen), while Boat 15 carried almost 70, including 13 crewmen, but only 4 women and 3 children. Murdoch
was less zealous in packing the lifeboats with women and children, whereas on the port side, Mr. Lightoller was
most strict in this regard and, therefore, took much longer in getting his boats off.
Collapsible Boat C was situated on the forward starboard side. It was attached to Boat 1's davits and lowered awaywith 39 souls aboard. First Officer Murdoch had to fire his pistol to maintain order during loading. Quartermaster
George Rowe was appointed by Captain Smith to command her (he was the man who helped Fourth Officer Boxall
fire the distress rockets). She picked up 4 more (for a total of 43). Rowe steered towards a sailing vessel, but could
not catch her (probably the SAMPSON).
Emergency cutter Boat 2 on the port side was launched by Lightoller around 1:45 AM. Fourth Officer Boxall was
given command along with a supply of green signal rockets. The boat carried 26 people, of which 21 were women.
All but 1 of the starboard boats had been launched by 1:40 AM, followed by the port side, 25 minutes later.
1:55 AM Boat 4, last of the conventional lifeboats was launched from the port side, 70 minutes after the order toload was given. Boat 4 was carrying 46 people. She was originally let down to A Deck, but nobody could board
because of Ismay’s windows, so brought back up to the Boat Deck, then re-lowered to A Deck after a seaman wasdispatched with the proper tool to open the window covers. This boat contained 36 women and children, and only
descended 25 feet to the water, because of TITANIC’s list. John J. Astor asked to board with his pregnant wife, but
was refused. Boat 4 remained nearby, and picked up 7 men from the water, but it leaked badly and required
constant bailing. Astor appears to have died when Funnel No. 1 toppled onto the submerged bridge, where a groupof men were clinging to the overturned hull of Collapsible Lifeboat B.
At 2:05 AM Collapsible Boat D lowered from the Boat 2 davits, forward on the port side. By this time the sea waslevel with B Deck, so only lowered 2 decks. Her loading was supervised by Wilde and Lightoller, contained 40 to
46 people.
Collapsibles A and B were stowed on the roof of the officer’s deckhouse, behind the navigation bridge. B went
into the water upside down. Lightoller had given up on launching A, but men sitting on it went into the water with
it when the ship’s bridge dipped under, around 2:10 AM. Wilde and Murdoch were last seen trying to free up Boat
A on the starboard side. Neither officer survived.
At 2:21 AM the stern section of the TITANIC sankOn overturned collapsible Boat B: Wireless operator Harold Bride ended up beneath Collapsible B, he was later
picked up by Boat 12. The first group which reached it appears to have been crushed by Funnel No.1 when it
toppled forward. After this wireless operator Jack Phillips made it to Collapsible B, but died of exposure. 30 or somen clambered aboard overturned Boat B, balancing on the upturned bottom. They stood upright back-to-back for

over 2 hours, reciting the Lord’s Prayer in unison. This group included Lightoller, Archibald Gracie, the ship’s
cook and many others. They were taken aboard Boat 12 under Fifth Officer Lowe just after dawn, after being
summoned by Lightoller’s whistle. Lightoller then took command of Boat 12, which had also relieved Collapsible
D of some of her survivors, around 6:30 AM.
Unfurled collapsible Boat A: Men were attempting to slide her down off the deckhouse when the bridge dipped
under the waves, and the boat floated away right side up, but with her side screens down. Four men managed tostay aboard as the boat was swept off TITANIC. She was commanded by First Class Steward Edward Brown, who
served as an excellent witness in the British inquiry. 16 men eventually clambered aboard, out of the water, but only
between 11 and 14 survived, due to hypothermia. The survivors were removed by Collapsible D and Boat 14,
commanded by Fifth Officer Lowe shortly after dawn. Three dead were left in the boat.
25-year old Fifth Officer Harold Lowe was the officer who purposefully waited “for the people to thin out” (oruntil the cries died down) to go back in and try to recover survivors from the icy water. He only managed to recover
three people, one of whom died, thereby saving 2 out of the 1,517 who were left to the frigid waters. Boat 10 joined
Collapsible D and Boats 4, 12, and 14 to form a small flotilla linked by ropes and commanded by Fifth Officer
Lowe.
Collapsible Boat C, with Bruce Ismay aboard, was picked up by CARPATHIA around 6:15 AM. Collapsible D
arrived in tow by Boat 14, flagship of Lowe’s flotilla, around 7 AM. Boat 12 was the last to transfer her more than70 people to the CARPATHIA, between 8:15 and 8:30 AM. Second Officer Lightoller, the senior surviving officer,
was last to come aboard CARPATHIA.
THE SHIP ON THE HORIZONThe S. S. CALIFORNIAN was a 6,223 ton Leyland Liner out of Liverpool, bound for Boston with a cargo of cotton.
She was built in 1901-02 in Dundee, Scotland; 447 feet long with beam of 54 feet and accomodations for 47
passengers (none carried on this trip). The CALIFORNIAN was carrying a crew of 55 and her design speed was just
13 kts. She was commanded by Stanley Lord, b. 1877 in Bolton, England, his 4th command in 6 years.
The CALIFORNIAN left Liverpool on April 5, 1912 bound for Boston, MA Her wireless received several ice
warnings on Saturday April 13th. She sighted icebergs to south near dusk on Sunday April 14th, while travelingwestbound. She notified ANTILLIAN at 6:30 PM that icebergs sighted, this message overheard by TITANIC.
At 10:09 PM (TITANIC time) Captain Lord ordered FULL ASTERN, then STOP, swinging helm hard-to-port tobring the ship around onto a northeast heading, an emergency stop. Although isolated icebergs had been sighted,
Captain Lord correctly deduced he had stumbled upon the edge of a large ice field. This was 1-1/2 hours before
TITANIC’s collision. He calculated their position by dead reckoning as being 42o 5' N and 50o 7' W. If his
calculations were correct, he was initially located about 13-1/2 nm NW of where TITANIC struck the iceberg at
11:40 PM. He should have drifted to within about 11-1/2 to 12-1/2 miles of TITANIC by the time she arrived, 1-1/2
hours later.
At 10:40 PM, the CALIFORNIAN’s bridge watch observed a large ship approaching from the southeast. At 11:20
PM Captain Lord observed this vessel’s green starboard navigation light, indicating westbound travel, and her whitemasthead light, as well as numerous deck lights. This could only have been TITANIC. Captain Lord estimated theship appeared to be about 5 nautical miles (nm) south of their position, and they were drifting SSE. The maximum
visibility from Lord’s bridge [49 feet above ocean level] would have been about 8 miles. Taller objects, such as the
TITANIC’s bridge could be seen from further away.
CALIFORNIAN’s Marconi wireless operator was 20 year old Cyril Evans, who had just 6 months experience.
Captain Lord ordered Evans to notify TITANIC he was stopped and surrounded by ice. Evans began to do so, but
was rudely cut off by TITANIC wireless operator Jack Phillips. Unfortunately, Evans did not leave his emergency
bell switched on when he turned off his set at 11:20 PM and TITANIC did not broadcast her first distress call until
35 minutes after striking the iceberg, around 12:15 AM.

Third Officer Charles Groves tried to raise the ship with his Morse [signal] Lamp, but received no response. Just
after midnight, Second Officer Herbert Stone took over the watch. He saw a ship about 5 nautical miles (nm) south
and a little west, with one white masthead light and a portside red navigation light. This was probably due to somedrifting of the TITANIC, which was dead-in-the-water. All the while, CALIFORNIA was also drifting, swinging
slowly clockwise, from ENE to WNW, through 225o. If TITANIC also drifted clockwise a similar amount, her red
portside navigation light should have been facing the CALIFORNIAN.
Around 12:30 AM bridge watch on the CALIFORNIAN began noticing TITANIC’s socket signal rockets being fired
off. In the exceptional weather conditions of that evening the rockets may have been visible from 20 miles away, if
not very far above the horizon. However, several of the officer’s also testified that they could see the lighting of therockets as well as the launch, suggesting that they were 8 to 10 miles distant at most.
Captain Lord left the CALIFORNIAN’s bridge around 12:45 AM. At 1:15 AM Second Officer Stone reported thatthe ship on horizon is steaming away to the southwest, also reporting seeing white rockets low in sky and thought tobe from another ship, further to the south. For unknown reasons, the CALIFORNIAN’s officers did not associate any
sort of distress by the firing of the white socket flares. The headward list of TITANIC would have appeared identicalto a ship sailing away to the south, over the horizon.
At 2:05 AM Cadet Gibson on CALIFORNIAN reports to the Chart Room he has observed 8 white rocket firings, andthought he saw a tramp steamer steam away (actually the lights of the TITANIC fading as she goes down by thehead). Gibson is told by Second Officer Stone to inform the Captain Lord, which he does, but does not respond to
Captain’s inquiries about having been awoke. Second Officer Stone and Cadet Gibson were clearly afraid of
Captain Lord, who was known as a stern disciplinarian. Second Officer Stone should have awoken the Captain.
Captain Lord awakes around dawn, 4:40 AM (local time), and notes a steamer is visible about 14 miles off, with
one yellow funnel and 4 masts, but not on the bearing of rockets observed during the midwatch. This appears tohave been the SATURNIA, south of the MT TEMPLE (the MT TEMPLE had extinguished her lights while DIW).
At 5:15 AM Stewart informs Captain Lord that his wireless has reported a ship sunk the previous night at 41o 46' N
and 50o 14' W. Message is taken from the MOUNT TEMPLE, situated on the opposite side of the offending ice field.
At 5:40 AM the MT TEMPLE informs them that the sunken ship was the TITANIC. At 6:05 AM Captain Lord setssail for the indicated [Boxall’s] position, which is WEST of the ice field. CALIFORNIAN picks her way carefully
across the ice field in the early morning light. At 7:35 AM CALIFORNIAN arrives at the indicated position, but seesnothing.
During the 1912 American and British inquiries, Captain Lord comes across as very defensive and self-serving,causing few to believe him. The public outcry following the TITANIC disaster caused Leyland Lines to discharge
Captain Lord. The British re-opened inquest into the CALIFORNIAN in 1920, 8 years later. Lord spent the later
years of his life fighting to have the Merchant Marine Board reopen his case and reconsider all the facts, retaining alawyer. He became very agitated at the manner of his portrayal in the 1958 film A Night to Remember. He died afew years later, in January 1962, almost 50 years after the TITANIC sank.
THE OTHER SHIP NEARBYThe MT TEMPLE had left Antwerp, Belgium on April 3, 1912. She had received the same ice warnings as TITANIC
via wireless on Saturday April 13th, plotted these, and decided to steer south, around them. She stopped around
midnight April 14th (New York time, would have been about 2 AM local time) because of TITANIC’s CQD(distress) signal, notifying her that TITANIC had struck an iceberg and to please render aid and assistance. MT
TEMPLE changed course and headed for TITANIC’s original position, then changed course to Boxall’s corrected
position. Around 2 AM she believes she has sighted the TITANIC. She encounters the ice field around 3 AM anddoubled her lookouts. They see a small schooner showing a green starboard light about 1-1/2 miles ahead (this musthave been the Norwegian SAMPSON). She turned sharply to port (northward) to pass the schooner starboard to
starboard, but the light went out (SAMPSON had been engaged in an illegal seal hunting expedition to the Grand
Banks, so shut her navigation lights when approached).

18
Captain Moore of the MT TEMPLE stated that he shut down at 3:25 AM, about 14 nautical miles (nm) fromTITANIC’s reported position, and let his ship drift (some accounts say 2 hours, the captain stated 3 hours, between
3:25 and 6:30 AM), before attempting to cross the ice field (everyone was a bit nervous about hitting an iceberg by
this point). He estimated the ice field as being 20 miles long and 5 to 6 miles wide. He came to Boxall’s corrected
position around 4:30 AM, and circled, seeing nothing. He did note the steamer SATURNIA ahead and south of his
position. Captain Moore estimated that Boxall’s position was actually 8 miles east of that broadcast, based on
CARPATHIA’s position (drift was about 1 knot per hour SSE that evening). MT TEMPLE then sighted the German
steamer FRANKFURT to the northwest and Russian steamer BIRMA to the south (which came up from a position
about 70 nautical miles away). She communicated with both via her wireless set.
At 6 AM MT TEMPLE sighted the CARPATHIA across 6 miles of ice field, on the east side of the field. At 8:30
AM CARPATHIA sends her a message regarding her pick-up of TITANIC survivors, and advises MT. TEMPLE there
is no need for her to stand by. They searched until 9 AM.
NORWEGIAN SCHOONER SAMPSONThe SAMPSON was a 506 ton Norwegian schooner, 148 feet long, commanded by Captain C.J. Ring. First Officer
named Hendrick Naess. Naess makes a deathbed confession in Norway in 1962, stating that he observed the
TITANIC’s white socket flares from close aboard on evening of April 14-15, 1912, but would not render assistance,
thinking these to be signals from a revenue cutter, aiming to apprehend the SAMPSON, because she had been
engaged in illegal hunting of seals off the SE Canadian coast and the Grand Banks. She was owned by a sealing
company in Trondheim, Norway. Naess said they observed the rocket firings, then doused their lights, being fearfulthat these might be a signal for them to heave to.
Some have discounted the Naess report because the SAMSON was logged in an Icelandic port on April 6th and April
20th. However, if the were engaged in illegal sealing activities, such an entry could have been purchased and served
as a convenient alibi should the authorities probe her whereabouts.
THE DOROTHY BAIRD
A fishing schooner from Gloucester, Massachusetts was also reported to be in the general vicinity when the
TITANIC foundered. This ship has been offered up as an alternative for the SAMPSON, but little corroborating
evidence exists.
S.S. CARPATHIA COMES TO THE RESCUE
S.S. CARPATHIA was a Cunard liner of 13,600 tons, built on the River Tyne in 1902-03 for transatlantic emigrant
service. She was 540 feet long and 65 feet wide, with a single funnel, capable of 14.5 kts. She was upgraded in1905 to carry 100 first class, 200 second class and 750 third class passengers. Commanded by Captain Arthur
Henry Rostron, born in Bolton, Lancashire in 1869, he joined Cunard in 1895. Promoted to Steamer Captain in
1907. CARPATHIA had 740 passengers embarked when she sailed from New York on Thursday April 11th, boundfor Gibraltar and the Mediterranean.
Her only wireless operator was Thomas Cottam, age 21. He had a busy day Sunday April 14th, beginning at 7 AM,
unable to turn in till midnight. But as fate would have it, he did not turn his set off because he had not received an
acknowledgment of a message he had sent to the liner PARISIAN earlier that evening. Idly scanning the airwaves hetuned into the Cape Cod transmitting station (call sign MCC) and overheard transmissions to the new liner TITANIC.
He wondered if TITANIC was receiving these, so he addressed a wireless inquiry to TITANIC’s call sign MGY:
I say, OM [old man], do you know there is a batch of messages coming through for you from
MCC?
Before he could finish the transmission, he was interrupted by the reply from TITANIC’s Jack Phillips:
Come at once. We have struck an iceberg. It’s CQD OM [old man]. Position 41o N, 50o 14' W

J. David Rogers - Notes on loss of the RMS TITANIC

19
Cottam replies: Shall I tell my Captain? Do you require assistance?
Phillips replies: To MPA [CARPATHIA], yes, come quick. This was received by CARPATHIA at 12:25 AM local
time (12:35 AM on the CARPATHIA, about 58 nautical miles (nm) southeast)
CARPATHIA was only designed for a flank speed of 14.5 kts, but Captain Rostron diverted all steam to the ship’s
engines, locking down all auxiliary power, and achieved 17.5 kts for the run-in to TITANIC’s reported position, 58
miles distant.
Last message received from the TITANIC was at 1:45 AM, which stated “Engine room filled up to boilers”.
CARPATHIA steers a course of 308o true, or N 52o W. At 2:30 AM she sights green flares fired from Fourth Officer
Boxall’s lifeboat, but TITANIC survivors don’t see CARPATHIA’s responding white rockets till 3:30 AM.
CARPATHIA arrives at the scene at 4:00 AM, about 20 minutes before dawn, not quite 3-1/2 hours since picking up
the distress call. She has come from the southeast, across relatively clear seas. She sets sight on Boxall’s green
light, and records the pick-up position at 41o 40' N, 50o. W, 7 to 8 nautical miles (nm) southeast of Fourth Officer
Boxall’s “corrected position”. CARPATHIA secures Boxall’s lifeboat to her starboard side at 4:10 AM.
When the sun rose CARPATHIA counted two dozen large icebergs (over 200 feet showing) in the vicinity. Captain
Rostron noted that while picking up survivors, he noted “hardly a bit of wreckage floated, just a deck chair or two, a
few lifebelts, good deal of cork, no unusual amount of flotsam. Only saw one body
TITANIC Lifeboats D, 14, 4 and 15 were cast adrift after pick-up. The other 13 lifeboats(1,2,3,5,6,7,8,9,10,11,12,13 and 16) were hoisted aboard CARPATHIA between 4:10 and 8:30 AM. Rostron reports
these as: 13 lifeboats, two emergency cutters and 2 collapsible, 2 overturned [collapsible] boats sighted. One regular
lifeboat noted to be capsized.
TITANIC SURVIVORS
1,517 people lost their lives on TITANIC, including the Captain, Chief Officer, First Officer and Third Officer; theentire engineering staff of 32 officers and men (who stayed below to keep the lights going); both Ship’s doctors; the8-man ship’s band; Thomas Andrews and his 8-man guarantee party sent by Harland & Wolff; and all 5 postal
clerks.
706 people survived, accounting for 31.8% aboard. Breakdowns by group were: 199/329 of the first classpassengers (60%), including 93 % of the women and children; 119/285 of the second class passengers (42%),
including 81% of the women and children; 174/710 of the third class passengers (25%), including 47% of thewomen and children; and 214/899 of the ships crew (24%), including 87% of the women (20 of 23). 27% of theboys and 45% of the girls in Third Class (steerage) survived.
The loss of life on the TITANIC was the worst civilian maritime disaster until April 1980, when a Philippine
passenger ferry collided with a tanker and 4,375 drown.
FORENSIC ENGINEERING IN 1912
Edward Wilding, Harland & Wolff’s senior naval architect, subsequently testified at the British Inquiry, which
commenced in London on May 2, 1912. In the report dated July 30, 1912 Wilding stated that TITANIC would mostcertainly have survived a head-on collision with the iceberg, crushing the bow section back to the second watertightbulkhead. This would have killed 56 off-duty firemen berthed in the forecastle of the ship.
Wilding also calculated buoyancy loss, using reports of observations by the survivors, in particular the officers.
TITANIC remained afloat for 2 hours and 41 minutes. Wilding calculated that the iceberg-induced hull damage
extending back to Coal Bunker 10/Boile Room 5 was likely a series of discontinuous cracks, irregularly distributed
along the first 200 to 300 feet of hull, with an average area of breech of only 12 square feet. The average width of

J. David Rogers - Notes on loss of the RMS TITANIC

20such a crack would have been only 3/4 inch, which caused him to speculate that buckling of the hull plates at rivet
laps was most likely responsible mechanism.
Wilding also calculated that 16,000 tons of seawater taken into the bow section would have been required to bring
the bow down 40 feet, where it dipped beneath the surface around 2 AM.
CREDIBLE FORENSIC EVALUATIONS SELDOM REPORTED IN THE MEDIA
Wilding’s statements came months later, after careful scrutiny of the evidence and a great number of engineering
calculations. In addition, White Star was obliged to take TITANIC’s sister ship OLYMPIC on forensic sea trials tomeasure response times, turning radii and ability to take evasive action under flank speed when fully loaded. The
results of these tests were of extreme import in estimating what occurred when First Officer Murdoch attempted tomake an evasive reverse turn around the iceberg.
These credible evaluations were largely overlooked by the media coverage of the day, similar to reporting today.
When the news arrives months later it was considered “cold”. Wilding’s estimate of 12 square feet of opening has
recently been corroborated by the French team who used geophysical techniques to evaluate the character and extent
of damage to TITANIC’s forward starboard side. This team also discerned that the damage was discontinuous, as
Wilding also alleged. The separations appear to have occurred at laps between adjacent hull plates, where rivets
had been sheared off. This discontinuous tearing appears to have been fostered by blunt indentation of one of theplates, as would be expected from the hull scrapping against a dense hard object.
ACTUAL POSITIONS BASED ON FORENSIC ANALYSESThe TITANIC wreckage was discovered in 1985, some 13 miles from Fourth Officer Boxall’s reported position. It
would appear that TITANIC was steaming at 41o 47' N and 49o 55' W when she struck the iceberg. The hull sank at
41o 43.6' N and 49o 56.9’ W. During the post-failure inquiries in 1912, the CALIFORNIAN’s position was
represented to have been 19 nm from TITANIC, which implies that officers standing watch on here elevated bridge
would not have been capable of making any direct observations of the TITANIC, but were observing a “mysteryship” supposedly situated between TITANIC and CALIFORNIAN. This seems incredulous, given the sheer volume
of corroborating testimony from the surviving officer’s on both vessels’ navigation bridges. But, the events
observed and described by CALIFORNIAN’s officers, including observation of Boxall’s rocket firings, suggests they
were within direct line-of-sight of TITANIC; not to mention the mutual observation of bridge navigation lights, fromboth ships. If Captain Lord’s dead reckon position was accurate, he would have been about 10.5 to 12.5 miles fromTITANIC when she struck the iceberg, and 1 to 2 miles closer when she foundered. A sinking ship would not drift
as fast as a trimmed ship.
PROBABILITY OF OCCURENCE
The winter of 1911-12 was unusually warm. The warmth increased iceberg calving at Disco Bay, Greenland andbrought the cold Labrador Current further south into warm north Atlantic Gulf stream than in previous 40 years.
TITANIC’s Captain Edward J. Smith was the most experienced ship’s captain on the North Atlantic, having
commanded ships along those sea lanes for 25 years. He was also the highest paid mariner in the world at the time.
He didn’t take iceberg warnings as seriously as he should have and forgot to account for the southward drift of thosesightings when these were plotted on the TITANIC’s navigation bridge.
The environmental conditions surrounding the TITANIC’s untimely demise were extremely rare: the night was
moonless; the sea temperature was 29 degrees Fahrenheit and the TITANIC’s fresh water bilges were freezing up.
There were no waves, the ocean was at Sea State 1, unusually calm, described as “being like a millpond”. These
windless and waveless conditions prevented phosphorescent wave wash against the icebergs, which was how they
were normally identified at night by watchmen stationed in the crow’s nest, about 120 feet above the water. Withbinoculars the watchmen were usually able to identify icebergs at ranges of between 6,000 and 2,000 yards. The
watchmen were without binoculars that evening because they had unknowingly been stowed in the Second Officer’s
cabin. The speed of the ship was about 22.5 kts and the wind chill factor on the watchmen would have been about 27o F, bring the ambient air temperature from 35o down to just 8o F. The iceberg that sank the Titanic was not
identified until the ship was within about 500 yards, an extremely close range to enable effective evasive maneuvers.

At the time the environmental conditions fostering the April 1912 tragedy were universally judged to have been
unusual, referred to as “the mildest winter in some 30 or 40 years”. There had not been any rational attempt tomaintain records of sea surface temperature and iceberg migration until the TITANIC sank. An International North
Atlantic Iceberg Patrol was established in 1912 and that body has quietly recorded environmental conditions eversince. The next time icebergs emanating from Greenland drifted into the North Atlantic sea lanes to the same
latitude as in April 1912 was in March-April 1957, necessitating shifting of Trans-Atlantic steamers 100 nautical
miles southward. It was exactly 45 years later and it was also the ONLY time such an advisory has been issued
since 1912. Most oceanographers and climatologists disagree on the recurrence frequency of the southerly shift, butwould agree that it’s likely on the order of one-in 50 years or thereabouts.
IMPACTS ON MARTIME DESIGN
The impacts of the TITANIC sinking on maritime safety legislation and naval architecture are legion. Needless tosay, sufficient floatation and lifeboat space for each passenger, mandatory lifeboat drills and provisioning oflifeboats was immediately instituted.
On the design front, we have the TITANIC tragedy to thank for the rapid development of watertightcompartmentalization (as opposed to watertight bulkheads); sluice valves between bulkheads for bilge pumps, sothese could be connected in unison; damage control training which emphasized pumping and counter-flooding
measures; increased maneuverability (larger rudders and voluminous hull skegs forward of the propulsion screws);
reversible Parson’s turbines; double hulls; and a host of other technical innovations, which saved thousands of lives
during the First and Second World Wars. Damage control training became routine in the world’s modern navies.
During the surprise attack on Pearl Harbor in December 1941 junior officers standing watch on a quiet Sunday
morning ordered watertight doors closed and initiated counter-flooding to prevent capsizing of a half dozen heavily
damaged battleships and cruisers, saving thousands.
A most descriptive quote would be: The terrible “ifs” tend to accumulate - Winston Churchill, 1915
