A catamaran-type boat having two or more demi-hulls that are connected by a wing-shaped superstructure is disclosed. The demi-hulls are further connected by two or more transverse hydrofoils. A tunnel is created between the demi-hulls and the superstructure. The shape of the superstructure takes advantage of the airflow through the tunnel to provide aerodynamic lift. The hydrofoils serve two purposes. The first is to provide hydrodynamic lift, and the second is to cancel wave build up between the hulls. The wave cancellation assists the stability of the ...
[ I claim:] [1.] A boat capable of sustained, stable travel through water at speeds greater than 50 knots, said boat comprising:(a) a plurality of substantially parallel catamaran hulls, wherein the space between two adjacent said hulls forms a channel on the surface of the water;(b) a superstructure connected to and supported by said hulls, wherein forward motion of said boat produces aerodynamic lift on said superstructure through the wing in ground effect, the aerodynamic lift being at least about thirty percent of the weight of said boat; and(c) a pl...
