Abstract: A deep vee entry hull having a central running surface extending fore and aft thereof, the cross-section thereof transitioning from a pronounced vee to a nearly planar configuration from fore to aft of the hull, the central running surface narrowing at its aft end portion and being flanked, in the after portion of the hull, by first and second inner running surfaces, intermediate running surfaces and outboard running surfaces, the first inner running surfaces being planar and exhibiting, with the central running surface, a vee configuration in cross-section; and the intermediate and outboard running surfaces exhibiting a cross-section of uninterrupted concave curvature commencing amidship to the extreme aft exit end thereof; the hull including sidewalls and the curvature of the concave intermediate and outboard running surfaces, at any given fore and aft positions, are constant, up to and including, an outer lip of said outboard running surfaces merging the same with the hull sidewalls; the intermediate and o
