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 outboard running surfaces being planar in the forward portion of the hull and transitioning to the concave configuration amidship, and the depth of the concave configuration gradually increasing from amidship to stern.

(b) sidewalls;
(c) first and second inner running surfaces flanking said central running surface, in the after portion of the hull, and said first inner running surfaces being planar and exhibiting, with said central running surface, a vee configuration in cross-section;
(d) intermediate running surfaces flanking said central running surface in the after portion of the hull, exhibiting a cross section of uninterrupted concave curvature commencing amidship to the extreme aft exit end thereof;
and
(e) outboard running surfaces flanking said central running surface in the after portion of said hull and exhibiting a cross-section of uninterrupted concave curvature commencing amidhsip to the extreme aft exit end thereof, the curvature of said concave outboard running surfaces, at any given fore and aft position, constant up to and including an outer lip merging the same with the hull sidewalls, said outboard running surfaces being planar in the forward position of the hull and transitioning to said concave configuration amidship, and the depth of said concave configuration gradually increasing from amidship to stern.
