ABSTRACT:
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.
