摘要
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 craft by providing a relatively flat surface for the wing, to provide stable additional lift through the "wing in ground" effect. The combination of hydrodynamic lift, wave cancellation, and aerodynamic lift decreases the ship's drag and increases its speed.
