An improved V-bottom hull for sport/utility boats is formed with intermediate lifting strakes along the aft half of the hull bottom. Such intermediate strakes are positioned laterally along the boat bottom between the planing pad step and the chine. These intermediate strakes are proportioned to provide a strake riser face width that is about 1 in. or greater and a horizontal tread width of the strake of less than about 3 in. An included angle between the tread surface and the riser face is preferably between about 95.degree. to about 110.degree.. The riser face intersection with the adjacently higher bottom surface panel is faired with a longitudinal fillet.

[ I claim:] [1.] A boat having modified V-bottom hull surfaces and a transverse transom plane, bottom surfaces of said hull comprising:a planing pad disposed substantially symmetrically about a vertical center plane of said boat to extend forwardly along said bottom surface from said transverse transom plane, said planing pad being laterally delineated on each side of said vertical center plane by elongated steps having riser faces spanning between a substantially horizontal bottom surface of said planing pad and respective first bottom panels disposed within respective first deadrise planes; and,a pair of intermediate lifting strakes extended forwardly along said bottom surface substantially from said transverse transom plane, said intermediate strakes having substantially planar tread surfaces emerging horizontally from a respective first bottom panel along lines laterally spaced from adjacent planing pad riser faces, said tread surfaces having a horizontal width terminated by a corner intersection with respective strake riser faces, said strake riser faces having an elongated width between said corner intersections and respective second bottom panels disposed within respective second deadrise planes; the width of said strake tread surface being about 3 in. or less and the width of said strake riser faces being about 1 in. or more whereby said first deadrise planes are substantially below said second deadrise planes in the proximity of said strake riser faces.
