Patent ID: 8701583

Claim:
A hydrofoil-assisted multi-hulled watercraft having a longitudinal center of gravity and including at least two hulls which define a longitudinal center line between the hulls, the hulls being spaced apart and connected by an upper superstructure spaced above a waterline so as to define a tunnel between the hulls, the watercraft including a hydrofoil which extends between the hulls at a position wherein a center of lift of the hydrofoil is disposed proximate and relatively forward of said longitudinal center of gravity of the watercraft, each hull defining an elongate step formation which is disposed proximate and relatively forward of the longitudinal center of gravity of the watercraft and which extends transversely relative to said longitudinal center line, the hydrofoil having opposite outer ends which are each disposed adjacent an inner position of a different one of the elongate step formations in an arrangement wherein the hydrofoil and each elongate step formations is disposed in a different longitudinal flow stream.
