Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
103 words
A deep vee entry hull having a central running surface extending fore and aft thereof flanked, in the after portion of the hull, by intermediate and outboard running surfaces; said intermediate running surfaces being planar and exhibiting, with said central running surface, a V configuration in cross section; said outboard running surfaces being concave in cross section; the curvature of said concave outboard running surfaces, at a given fore and aft position, being constant up to and including an outer lip merging the same with the hull side-walls; and said outboard running surfaces terminating at the aft ends thereof in transverse wedge means.
Claim 2
Dependent Claim
103 words
A deep vee entry hull having a central running surface extending fore and aft thereof flanked, in the after portion of the hull, by intermediate and outboard running surfaces; said intermediate running surfaces being planar and exhibiting, with said central running surface, a V configuration in cross section; said outboard running surfaces being concave in cross section; the curvature of said concave outboard running surfaces, at a given fore and aft position, being constant up to and including an outer lip merging the same with the hull side-walls; and said outboard running surfaces terminating at the aft ends thereof in transverse wedge means.
Claim 3
Dependent Claim
24 words
The hull of claim 1 wherein said wedge means are limited in their transverse extent to the inboard halves of said outboard running surfaces.
Claim 4
Dependent Claim
34 words
The hull of claim 2 including outboard bow chines extending aft from the bow of said hull and terminating amidship in abrupt steps continuous with the outer lips of said outer concave running surfaces.
Claim 5
Dependent Claim
43 words
The hull of claim 3 wherein said deep vee entry hull tapers aft to a more flattened shape amidship and transitions rearwardly thereof to terminate in a modified gull wing appearance in cross section as a function of the concave outer running surfaces.
Claim 6
Dependent Claim
39 words
The hull of claim 3 wherein the outboard running surfaces are planar in the foreward portion of the hull and transition to said concave configuration amidship; and the depth of said concave configuration gradually increasing from amidship to stern.
