This invention is an improved boat hull design for stable operation as a planing-type hull in a wide range of water conditions. The hull is comprised of a substantially V-shaped central hull portion and a pair of adjacent side floats, one on each side of the central hull. The inner walls of the side floats are substantially vertical, and the floats are stepped upwardly at approximately midships, such that the rear portion of the side floats is substantially horizontal, or parallel to the plane of the water surface. At least one pair of flat surfaces are formed along the bottom portion of the hull positioned at the intersection of lowermost strakes and steps formed on each side of the hull, so as to provide substantially improved stability and attitude when running at high speed on rough water. A dihedral tunnel is formed by the concavely-curved surfaces of the central hull in combination with the inner walls of the side floats. The inner walls extend rearward beyond the steps to approximately 3 feet forward of the stern or transom, becoming “traps”that contain hydrodynamic forces helping to provide lift under the hull.

An improved boat hull designed for stable operation when planing in rough water conditions, said hull having a bow and transom, a forward portion extending longitudinally from said bow to approximately midships, and a rear portion extending longitudinally from approximately midships to said transom,
An improved boat hull designed for stable operation when planing in rough water conditions, said hull having a bow and transom, a forward portion extending longitudinally from said bow to approximately midships, and a rear portion extending longitudinally from approximately midships to said transom, comprising: a substantially V-shaped central hull portion having a center line area extending from said bow to said transom; a pair of side portions , one on each side of said central hull portion, said side portions being longitudinally symmetrical, said side portions comprising: a pair of side floats, one float on each side of said central hull portion, and having inner wall surfaces adjacent the central hull portion; a pair of outer surfaces, one on each side of said central hull portion, having upper and lower ends, inclined upwardly and outwardly with respect to said central hull portion, and extending over said forward portion; a pair of afterplane areas, one on each side of said central hull portion, positioned in the rear portion between said center line area and said outer surfaces, and extending over said rear portion; a pair of substantially flat surfaces located in the rear portion between the outer most ends of the afterplane areas away from said center line area and the lower ends of said pair of outer surfaces, said flat surfaces extending forward from said transom to approximately midships; said inner wall surfaces adjacent said central hull portion being substantially vertical and defining, in combination with said central hull portion, a dihedral tunnel, and forming, in combination with said outer surface, a bottom edge of said side portions, said bottom edge extending to a depth greater than that of said center line area of said central hull portion, over a substantial length of said forward portion; and a second pair of flat surfaces formed along the forward portion of said boat hull, with one forward flat surface located on each side of said boat hull, said flat surfaces extending longitudinally forward from approximately midships to approximately the middle of the forward portion.
