Abstract: A water vehicle particularly suited for recreational use and designed to simulate the control and excitement of motorcycles, dune buggies and the like. These water vehicles are characterized as having a forward planing surface and rear hydrofoil members disposed so as to support the majority of the weight of the vehicle and passengers when operating at high speed. Sufficient lateral buoyancy is provided for flotation and low speed operation by a pair of spaced apart float assemblies toward the rear of the vehicle. The winglike members between the float assemblies and the vehicle body and the other hydrodynamic surfaces are designed to allow transition from low speed to high speed operation with a minimum of propulsive power required. Power may be provided by conventional outboard motors of a reasonable range of sizes, with stable but responsive control during high speed operation being provided by a combination of the steering apparatus and the spacing and support capability of the hydrofoils.
