Abstract
Abstract The disclosure is directed to a sailboat which is constructed for riding in surfboard fashion. The boat includes a sail which is symmetrically mounted for rotation about a vertical mast. The mast is disposed toward the rear of the boat in order that wind striking the sail may serve to both steer and power the boat, and to give the rider unobstructed forward vision. Direction of boat movement is determined by angular deviation or side tipping of the boat hull from its normal floating position. Tipping is affected by weight shifting on the part of the rider, and is sensed by apparatus which governs attitude of the sail with respect to the wind.
