ABSTRACT:
A boat hull is provided with a unique V-shaped bottom surface to increase lift, to reduce drag, and to maximize speed. The deadrise angle of the V-shaped bottom increases progressively from the stern to a point forward of the stern at a rate of 2.degree. to 6.degree. for each four feet of keel length, i.e., at the rate of about 1/2.degree. to 11/2.degree. per foot of keel length. The bottom surface between the stern and the forward point has a generally convex transverse cross section. The keel is substantially straight from the stern to the forward point and then curves upwardly to the bow.
