thread_title:  Wave Piercing Catamaran 

message: ----
Catamarans are less likely to capsize in the classic 'beam-wise' manner but often have a tendency to 'pole-axe' (or 'pitchpole') instead - where the leeward (downwind) bow sinks into the water and the boat 'trips' over forward, leading to a capsize.
This is an issue with a few older designs,  specifically the Hobie 14/16,  that is not shared by most modern designs,  i.e. Nacra/Inter 20 and a lesser degree the F18 & F16. --I20-312 03:04, 1 May 2007 (UTC)

thread_title:  Pitchpoling/triping on the bow is an old school problem 

message: In the article it is stated that:
Currently, most individually owned catamarans are built in France, South Africa, and Australia.
I think the Hobies are the most numerous in the world - where are these made?  Would prefer to see numbers that indicate how many produced in each of these countries or percentage.
Can someone explain how a sail catamaran can reach a speed 1.5 times that of the wind?  My basic understanding of sailing gives a 100% wind-speed as an ideal top speed, without power or currents.  Once the boat goes faster, the wind is basically pushing it backward.  Manofthesea (talk) 18:36, 9 June 2008 (UTC)
replies: text: Well, at encouragement to look it up myself, I found articles that demonstrate the math for a sailed vessel to travel at an angle to the wind faster than the wind.  With low enough drag, the ship can travel (in sum) against the wind, faster than the wind.  But I did not understand that the sailed vessel can sail directly against the wind, faster than the wind.  Manofthesea (talk) 19:44, 30 August 2010 (UTC)
replies: text: The best speed of a multi is on a Reach or a Broad Reach, where you can achieve 1.5 times windspeed or slightly more. This is becase of aeordynamic effects and the absence of ballast wieght which allows the multi-hull to plane. The superstructure needs to present as low a drag as possible and the whole boat needs to be a light as feasible. Refernece the Gun Cat. Slamlander (talk) 14:59, 30 June 2011 (UTC)

message: "The catamaran was first discovered being used by the paravas, a fishing community in the southern coast of Tamil Nadu, India."
If it was being used, then that wasn't its first discovery. Are we claiming that its earliest recorded use was among the Paravas? The word "discover" doesn't convey that idea, quite. -68.191.214.241 (talk) 18:27, 15 July 2009 (UTC)

If "refeted" is a real word, please define it. Is it by chance a typo for "refitted"? Substantiation of this possibility is, e.g.,
Shipyard/Builder : Composite Works, France
Naval Architect : Jean-Jacques Coste
Stylist : Jean-Jacques Coste

thread_title:  Real word or typo? 

message: The following doesn't make sense to me--you don't have a hull resting on another hull.  Shouldn't the first use of "catamaran hull" be changed to something else,  maybe "catamaran deck", or "catamaran cockpit", or "the deck and main body of the boat", or "the deck and superstructure of the boat"?
"The Westamarans, and later designs, some of them consisting of a catamaran hull resting on an air cushion between the hulls, became dominant for all high speed connections along the Norwegian coast."

thread_title:  Another unclear sentence? 

message: Most references to tacking a multihull make some comment about backing the jib. This is guaranteed to put the brakes on!
I learned to tack properly after blowing a Hobie 16 jib out in a storm. It seems to fly against conventional wisdom, but the winning crews in Hobie nationals seem to do the same thing.....
Turn through the wind fairly slowly. Fast turns require significant velocity changes on the hulls and the rudders act as brakes. On a Hobie, get hold of the boom (or use the traveller) and pull it into the wind - gently so that you are not stalling the main. This has the effect of pushing the stern of the boat around. Stop moving the boom across when it is in the correct position for the new tack. That's it! The boat keeps moving through the tack, losing much less speed than it does when backing the jib.
The maneuver works equally well on large multihulls and backing the main will even get one out of irons (provided you know how to steer backwards). Those wide travelers make backing the main easy!
Given the objection that many sailors express to tightening the main in a tack, I was reluctant to put this in the main article until a few others support the notion. Try it and see if it improves your tacking.— Preceding unsigned comment added by 189.172.201.161 (talk) 06:17, 16 October 2011 (UTC)

message: I propose to delete the two photos of the "monohull catamaran".  While I accepted they may underline the early etymology of the word "catamaran", it is confusing and unhelpful to show these pictures.  In modern usage, a catamaran is only ever a twin-hulled multihull. Arrivisto (talk) 08:59, 13 June 2013 (UTC)

message: The terms, amas and akas are inappropriately applied to catamarans here. An ama is an outrigger float, not a hull, and an aka is the structure that supports the ama. A catamaran has two hulls and a bridge deck connecting them. After pausing for further discussion of this point, I will edit, accordingly. Sincerely, User:HopsonRoad 18:39, 1 December 2015 (UTC)

message: It seems to me that the following sentence in Cruising is topsy-turvy nonsense: "Choosing a catamaran offers increased speed at the expense of reduced load per unit of cost. A cruising monohull may be as short as 30 feet (9.1 m), whereas Howard and Doane put the threshold for a cruising catamaran at 40 feet (12 m), to achieve the same accommodation of cruising accommodation for crew and supplies." A cruising cat of 9M has the accommodation of a 12M monohull; and a 12M cruising cat (such as the Catalac 12M) has the accommodation of a very much longer and more expensive monohull.

The idea that cats of 30 feet cannot be considered cruisers and are inferior to the same length monohull is simply false. Having cruised on a 30 ft cat with two adults, six kids and a german shepard, I beg to differ. An Iroquois Mk I on Lake Michigan. No 30 ft keelboat can do that in any kind of comfort.  — Preceding unsigned comment added by 108.230.164.139 (talk) 22:41, 28 September 2019 (UTC)
