Patent ID: 6935909

Claim:
A gliding board, comprising: an elongated element having a first end, a second end, and a pair of opposed edges, such that the first end, second end, and the pair of opposed edges form a perimeter that defines a contour of the gilding board in a base plane; a longitudinal axis extending in an end-to-end direction, and an arc of the longitudinal axis; a transverse axis extending in an edge-to-edge direction, perpendicular to said longitudinal axis, and an arc of the transverse axis; and an upper surface, such that a rider may be positioned on the upper surface; a lower surface, such that the lower surface faces a fluid and the gliding board may glide over the fluid; wherein the lower surface defines a concave shape toward the lower side in a transverse cross section along the entire length of the board, and wherein an entire length of the lower surface is convex toward the lower side in a longitudinal cross section.
