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 side than the center of buoyancy can go. At this point, the righting force will disappear, replaced by a turning moment in the opposite direction. This can capsize the vessel at the point at which one pontoon is completely submerged. When using twin lateral pontoons, each pontoon should have enough buoyancy to bear the load of the entire vessel on its own. If the vessel is so heavy that either pontoon is mostly submerged when no lateral force is applied, it will be vulnerable to the pontoon effect. If sufficient lateral force arises (such as wind or shifting load), the
