ABSTRACT:
A sporting vehicle powered only by the energy of the occupant for travelling on bodies of water at unprecedentedly high speeds. The vehicle comprises a frame supported while stationary on hulls or floats, and including a seat for the occupant and a set of pedals for enabling him to cause vehicle movement either by an air screw or a water screw. The frame is suitably reinforced and includes a rudder which can be withdrawn from the water, to reduce its drag, when conditions are appropriate. Forward and rearward hydrofoils, of V-shaped configuration, are also provided for use at low speeds, a linkage being included for lifting the low speed hydrofoil above the water surface when appropriate vehicle speed has been achieved. Normally all hydrofoils depend from the frame below the floats, and levers are provided by which the occupant can vary the angles of attack of the hydrofoils to take best advantage of environmental conditions and vehicle speed.
