Abstract

An airless, stepped hydroplaning boat hull has one mid ship step. Two separated wetted planing surfaces are thereby established - a forward surface just forward of the step and an aft surface just forward of an aft edge of the hull. The angles of attack of each planing surface is 2.5 to 4.5 degrees, and are equal. The midship step is located longitudinally 0.55 to 0.65 times the projected water line length of the hull, measured aftward from a aftmost edge of an aft planing surface. The stepped surface has at least three levels of horizontal lifting strakes longitudinally measured from a forwardmost point to aft.(FIG. 1)
