Weta Trimaran Weta Trimaran The Weta 4.4 Trimaran is a 4.4 metre (14 foot) sailing dinghy conceived and developed in New Zealand from 2001-2006 by Roger and Chris Kitchen and others with design by TC Design's Tim Clissold. The boat is constructed from fibre glass and carbon fibre, and is popular as a racing boat or for recreational sailing. It has added stability and righting moment from the trimaran amas or floats. The Weta Trimaran is recognized as one design class by Yachting New Zealand, the French Sailing Federation, and the Royal Yachting Association in the UK. In 2010 the Weta Trimaran
Pontoon effect a trimaran with narrow-beam floats will simply submerge the lee float, exposing only the weather wing and that with a lesser moment. In practical sea situations the windage effect is greater than the buoyancy effect and so cruising trimarans with highly buoyant floats are more, not less, likely to capsize than those with less buoyant floats. A trimaran is best stabilised not by adding buoyancy on the lee float but adding weight to the weather float. This is the basis of the "cool-tubes" stability system invented by Tristan Jones and L. Surtees. A large-diameter pipe closed at the aft end
