ABSTRACT:
A high-speed water craft having twin streamlined hulls and a centrally located aerodynamic body structure. The aerodynamic body structure bottom surface has an S-shaped longitudinal profile which is positioned above the surface of the water and which provides a venturi chamber beneath the body structure. Aerodynamic forces created by air passing through the venturi chamber act to raise the craft out of the water and also produce stabilizing aerodynamic forces as the craft is propelled forward at high speeds. A streamlined hydrodynamic power pod is provided beneath the body structure to create an improved hydrodynamic environment which increases the efficiency of power means utilized to propel the craft.
