ABSTRACT:
A boat hull configuration that generates lift upon forward movement in the water caused by two lateral side keels that run along either side of the hull, and a bottom surface that joins the two sides keels, wherein the forward portion of the bottom surface has a concave configuration which provides a pivot fulcrum surface, and wherein the forward portions of the keels have an inward slant from the front rearwardly to channel and trap water and air under the hull and result in the development of a force directed upward against the fulcrum surface to produce planing lift during powered forward motion of the boat.
