Abstract:
1. A boat hull comprising: a bow and a stern, the stern having stern skirts; a waterline extending between said bow and said stern; a hull skirt on each sided of the hull; a pair of hull tunnels under the hull; a pair of stern skirt tunnels extending axially in a direction from a forward end of the hull skirt toward said stern; a pair of flexible cambered bow foils supported on sides of said bow beneath the water line, said flexible cambered foils being capable of controlling a flow within said stern skirt tunnels and creating a dense spray in said stern skirt tunnels while cushioning shock and lifting said bow; a first adjustable cambered foil in each of the hull tunnels mounted to the bottom of the hull skirt, a second adjustable cambered foil in each of the hull tunnels mounted parallel to the waterline and to the top of the hull skirt, and a third adjustable cambered foil in each of the hull tunnels mounted parallel to the hull, the three adjustable cambered foils being adjustably positioned within each of the hull tunnels in order to generate lift from a pressure being generated by the dense spray within each of the hull tunnels, a first cambered foil in each of the stern skirt tunnels mounted on a bottom of the respective stern foil skirt of each of the stern skirt tunnels; and a second cambered foil in each of the stern skirt tunnels mounted parallel to the waterline and on top of the respective stern foil skirt, in order to prevent air from escaping and to compress the dense spray and thereby lift the stern, wherein the hull is a V-bottom hull, with the flexible cambered bow foils mounted on opposite outer faces of the V-bottom hull.
