ABSTRACT:
A rider-balanced aquatic vehicle has a body with a seat for supporting a rider and a motor which provides propulsion for the vehicle, the front end of the body being supported by a steerable front ski and the rear end being supported by a hydraulic lifting surface on the lower surface of the body. A steering shaft is operatively connected to the front ski to control the attitude of the front ski for assisting in controlling the balance and direction of motion of the vehicle. The front ski is horizontally transversely pivoted and spring biased toward an upward and forward attitude, resulting in increased lift upon the initial movement of the vehicle and efficient planing when the vehicle is in motion. The lifting surface at the rear of the vehicle incorporates a tapering tunnel portion formed in the lower surface of the body and outwardly and downwardly extending wings joined to the side edges of the tunnel portion. The wings provide lift during straight running, but do not interfere substantially with the ability of a rider to roll the vehicle by leaning, and the tunnel gives increased lift to the rear of the vehicle during banked turns.
