Patent ID: 8702462

Claim:
A longitudinally reinforced elliptically contoured wave-riding board comprising: an elongated body having an elliptically shaped deck surface and an opposite bottom surface bound between a front nose, a back tail, a first side rail extending along a first edge of said elongated body between said front nose and said back tail, and a second side rail extending along a second, opposite edge of said elongated body between said front nose and said back tail, said elongated body being generally symmetric about a centerline thereof; a recessed center section extending downward from a surface of said elliptically shaped deck surface, said recessed center section defined by a front recessing edge extending generally perpendicular to said elongated body centerline, a first rail recessing edge being parallel and adjacent to said first side rail, a second rail recessing edge being parallel and adjacent to said second side rail, and a tail recessing edge being parallel and adjacent to said back tail; a central ridge extending upwards from a basin of said recessed center section and extending continuously between said front recessing edge and said tail recessing edge along said body centerline, said central ridge segmenting said recessed center section into two substantially equal recessed subsections, each one of said recessed subsections having substantially uniform depth and width between said front recessing edge and said tail recessing edge; a fin extending downward from said bottom surface; and at least one stringer as an integral part of said body, wherein said at least one stringer is a longitudinal member capable of strengthening said structure thereof; said stringer extending between said front nose and said back tail.
