Abstract
An apparatus and method for utilization as a gliding board, such as a wake surfboard. The apparatus is the lower surface 26 of said gliding board and is a curved planar surface in a saddle or anticlastic shape. The resulting curved planar lower surface 26 of the gliding board exhibits excellent gliding properties over a fluid medium.
Claims20
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 gliding 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;
- 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;
- and
- such that the lower surface is saddle-shaped, with the longitudinal axis convex towards the lower surface of the gliding board, and the transverse axis concave towards the lower surface of the gliding board.

- a lower surface, such that the lower surface faces a fluid and the gliding board may glide over the fluid;
- and
- such that the shape of the lower surface is determined by the arc of the transverse axis, and the arc of the longitudinal axis, with the arc of the longitudinal axis being asymmetric, such that a front end and a tail end of the gliding board is derived.
