A hull with a convexly down-stepped plane located in the aft section and a “V”shaped hull structure in the forward section. The “V”shaped section and the planar section are connected by a smooth, convexly shaped transition section that is convex in reference to the exterior of the hull and extends below the “V”section. The transition section can be provided with spray root deflectors. The planing surface extends substantially the full width of the lower portion of the hull and can have portions of its after portion upwardly displaced.

A hull having sides, chines, a lower section and a lower water-engaging surface, terminated at one end by a bow and at the other end by a stern, said hull showing a “V”shape in cross-section view with the apex of said “V”shape centered with respect to the breadth of said hull extending from said bow

A hull having sides, chines, a lower section and a lower water-engaging surface, terminated at one end by a bow and at the other end by a stern, said hull showing a “V”shape in cross-section view with the apex of said “V”shape centered with respect to the breadth of said hull extending from said bow along a major portion of the length of said hull, said apex of said V- shaped section being essentially straight along the sternward portion of its length and having more average slope in profile view along the foreward portion of its length relative to said sternward portion of said apex, a substantially planar surface extending essentially the full width of the lower section of said hull, down-stepped from said apex of section showing a “V”shape, and a transition section, convexly shaped, at least in the longitudinal direction, in reference to the exterior of said hull, extending between said chines, having less average slope in cross-section view than said sides at said transition section, and connecting said section showing a “V”shape and said substantially planar surface located on said lower water-engaging surface, wherein said caines originate foreward of said substantially planar surface, above said apex of section showing a “V”shape, and are disposed downward in the direction of said stern along said transition section, extending below said apex of section showing a “V”shape.
