Abstract
A catamaran adapted for high speed travel includes a first and second hull, or vaka, disposed transversely apart from one another and interconnected by an intermediate structure, or aka. First and second elongate air tubes are formed in respective interior sides of the vakas. Each air tube is in open communication with a leading end of the vaka within which it is formed and has a uniform depth from the leading end to the approximate center of gravity of the catamaran. Each air tube depth gradually lessens from the center of gravity to the stern. Both vakas are therefore thickened inwardly toward one another at about the center of gravity to create a gradually increasing constriction in air flow beneath the aka. An exhaust area begins where the constriction begins and extends to the stern.
