Abstract:
A sailboat hull with a bow, a stem, a starboard side, a port side, a keel, a longitudinal axis, a lateral axis, and a vertical axis, where each of said axes is perpendicular to each of the other axes, comprising:a first plane defined by said longitudinal axis and said vertical axis; a bottom surface, said bottom surface being symmetric with respect to said first plane; at least one starboard straight line; wherein said at least one starboard straight line lies on said starboard side of said first plane; wherein said at least one starboard straight line intersects said first plane at a point, where in a projection of said point on to a horizontal plane, defined by the lateral axis and the longitudinal axis, is proximate to or aft of said stern; a plurality of starboard cross sections located along said at least one starboard straight line; each of said plurality of starboard cross sections comprising: a hull contour defined by the intersection of one of a plurality of cutting planes and said bottom surface on said starboard side; an orthogonal line, said orthogonal line perpendicular to a line tangent to said hull contour, and intersecting said at least one starboard straight line, and said orthogonal line within the respective one of the plurality of cutting planes; and, wherein a portion of said hull contour proximate to said orthogonal line is symmetric with respect to said orthogonal line; wherein at least one of said plurality of starboard cross sections is located between &frac23;rds of the hull length Llwl and the bow of the hull; and, wherein said keel is symmetric with respect to said first plane.
