A windsurfing catamaran with a self-stabilizing wing. The wing is moved to the
correct position by counter balancing water pressure from a rotating central keel
connected to a central mast. The keel rotates in the opposite direction of the
wing when the wing is moved off center by wind. The keel rotates such that a greater
surface area is presented to water flow striking the keel. Water pressure on the
keel offsets wind pressure on the sails and returns the keel and mast back to an
upright position. This increases stability, lift, driving force, and speed. A central
catamaran platform provides hinged struts and shock absorbers between the rear
end of the central platform and planing hulls to reduce impact damage. The hinged
struts and shock absorbers reduce water drag and the braking effect of repeated
hull impacts with water resulting in a further increase in speed.
