ABSTRACT:
A catamaran sailboat is provided which has the ability to limit heeling from the wind forces, to thereby maximize the effective sail area and speed. The catamaran includes a deck assembly which may be selectively moved laterally between the hulls by the crew, and whereby the weight of the deck, mast, sail, rigging, and crew may all be moved in the windward direction to effectively counterbalance the wind forces. In one embodiment, the two hulls are each continuous along their full length, and in a second embodiment each hull comprises a pair of longitudinally aligned hull sections, with at least one hull section of each pair being rotatable about a vertical axis to effect steering of the craft.
