ABSTRACT:
A boat hull comprising a generally elongated body portion and port and starboard elongated sponsons disposed along the opposite side margins of the body portion and defining elongated running surfaces, the sponsons terminating at respective locations forward of the transom means but aft of the transverse midplane of the hull. A central sponson depends from the body portion centrally of the port and starboard sponsons and defines a further elongated running surface that extends from a location forwardly of the aft terminal ends of the port and starboard sponsons to the approximate location of the transom means. The sponsons, in combination with the body of the hull, define tunnels on opposite sides of the central sponson. These tunnels are open at their respective forward and aft ends for the flow of fluid therealong.
