Steam Yacht Building.

yachts are coming into fashion more and |
more. They are tavorites above all for
pleasure boats.
Mr. Byrue has built more and larger steam |
yachts than any man in Great Britain. What |
be says commands attention in any part Of
the world.
The following is list of the principal
steam yachts that have come from his hand.
Sunbeam. 565 tons, Norseman, 2ai Doh
hran, 40; Jason, All; Lancashire Witch,
400 Amy, $50; Farnese, 122 Gelert, 1873
Naurouna, 740; Rover, 600; Cuhona, 5l4
Gltana, SOS; Alva, 1910 Miranda, 365 Fo-
lette, 1859; Dart, 450.
The last five are constructed this year.
Mr.. Byrne stated that the yachts being
built now are bigger and faster than those
designed heretofore.
In regard to the new steam yacht Miranda
he said: !: "The steam yacht Miranda, which
is now exciting much interest in English
yachting circles as an important production
of this year, is 1853 feet over all and 1870 feet
between ''perpendiculars,' "a feet beam, is
teet inches deep, and has a draught OF
water aft of 10 feet inches. 1t Is designed
as an auxiliary screw steam yacht for long
ocean cruises. She ia built entirely of steel.
is of the highest possible class at Lloyds.
aud everything of the best has been used In
her construction. She 10 fitted up with new
triple expansion engines. The diameter OF
the high pressure cylinder is 13 inches, tn,
under 81 inches and the low pressure SO
inches and the length of stroke common t.
all is % inches. The crank shaft is of fiuted
compressed STEEL made by the celebrated
Witworth, of Manchester, England. In the
construction of the Miranda steel has been
used wherever possible, should say also
that the propeller is of gun metal (Bevis'
patent), two baded, with feathering of man
ganese bronze. The diameter is feet
inches, the pitch, of course, being variable
! at will. She has, in addition, boiler OF
steel, working at 150 pounds to the square
inch. The diameter of the boiler is IL feet
and the length feet inches, 1t is fitted
with Fox's corrugated furnaces, the whole
being, of course, made OF the highest quail
| ty of steel obtaiuabe
"This vessel, with nearly sixty tons OF
lead ballast in her, to enable her to carry
her large area of canvas, and with forty tons
Of coal in her bunkers sttains an sverag,
speed at sea of from 10t to II knots an hour
on a consumption Of very little more than 81
tons of best Welsh coal per dly. This result
has never before been obtained with ordin-
ary compound engines.
1.-The Miranda is a heavily spared shooper,
square forward, and has on many occasions
for days at time, been under canvas alone
and attained speed up to IL knots 0rigi.
nally she was INTENDED more for sailing
yacht than steam yacht, and we didn't
think at first that these engines would give
much more speed than knots, but we got
a big result out of the triple engine-from
| l0l to II knots The owner, Sir George
Lampson, was so perfectly delighted with
the success al d principle altogether that he
has given me instructions to design very
much larger vessel, of about $50 tons, which
is to be almost duplicate of the Miranda" !"
In reply to the question as to whether Mr.
Vanderbuilt's nsw yacht, the Alva, being
built at the Harlan & Holingworth yards at
Wilmington, De. woult cost $500, 900
"Let me see. Why, that is OILY e60 900
But still could have had her built in Eng
land by first class firm for e40, 900, aud
would have had her fitted out with triph
expansion engines, too. gave the order on
the Gath of February and sailed on the 25 h
gave no designs, but they know exactl,
what we wanted. A good deal of work
might have been saved in the building OF
this vessel. The type is much heavier than
those we have in England, and they have
no appliances heIe + building such huge
boilers. Yes. compound as well as the tri
pie expansion engines ere first introduced
oy the English, and there are now some
firms engage in manufacturing quadrnple
eng mes. OF cource u ere is a coatinLa' ad-
vance, and nave no doubt that there will
be still further improvements"
at has been said that the Alva will out
sail her cont act speed"
"Oh, that is all nonsense, this talking
about II knots an hour. Fifteen knots is
the contract speed on trial for the Alva, with
a sea speed in average weather of 10 knots,
which will be very economical speed. The
Alva is not racer. She is intended for a
comfortable home u ser. Mr.. Yaudelb bi
does not wish her to make great speed. He
wants good, comfortable boat. At 13
knots an hour the coal consumed would
probably not exceed 16 tons Of good Welsh
coal in England, but cannot say what it
