Abstract: A wakeboard binding plate assembly includes a disc and ring. The disc is sized to fit within the opening of the ring, with each of the disc and ring including irregular surfaces, respectively positioned to engage each other. The disc is mounted to a portion of a boot assembly of the wakeboard. The ring is adapted to be fastened to a wakeboard, with the disc held in place between the disc and a boot assembly for the wakeboard, engagement between the irregular surfaces of the disc and the ring preventing rotation of the disc. Loosening the ring allows the disc to rotate so that the boot assembly can be easily moved to a desired alignment.

Abstract: A water floatation board includes a pair of curved side fins for an increase in holding power of the board when in the matter, and without increasing drag during board use. Each curved side fin has a concave surface that faces a centerline of the board, and a convex surface that is opposite of the concave surface. The inner and outer surfaces merge to form leading and trailing edges, and a fin tip. The use of the concave surface allows the fin area to increase without an increase in fin depth, thus providing greater holding power without increasing drag.
