ABSTRACT:
A high speed, high efficiency, stable catamaran boat hull which comprises a boat hull structure having an under surface, a curved bow and a generally flat stern, a pair of spaced-apart sponsons on either side of the keel line of the hull and extending generally substantially from the bow of the hull, wherein the sponsons generally come to a point, to the stern of the hull. The sponsons generally have vertical, downwardly extending, inner side walls and a generally horizontal underwall connecting the inner walls to form an air tunnel, the inner side walls tapering inwardly from the bow to the stern of the hull structure to compact the air passing through the tunnel to lift the hull in operation. The sponsons also have outer, generally vertical, extending outer side walls to form a deadrise sufficient to maintain the hull structure in the water during operation, and a connecting under surface between the inner and outer walls, with a plurality of strakes extending from the connecting under surface and generally extending substantially between the bow and stern to provide a smooth, stable ride of the hull structure through waves in operation. A short, generally flat, horizontal keel on either outward side of the inner walls provides stability to the hull structure during high speed operation.
