  • Patent number: 7578715
    Abstract: A recreational water board for towing a person behind a water craft on or below the surface of the water. The board includes a substantially planar structure with a pair of wings on either side of a central axis of symmetry. Each wing has a leading edge and a trailing edge, the leading edge being swept-back to give the board a hydro-dynamically contoured profile. The board also includes handgrips to enable the board to be firmly gripped while being towed, and pairs of apertures arranged symmetrically on either side respectively of a central board axis for attaching a tow bridle to the board. The pairs of apertures define a pivot axis, perpendicular to the central axis, about which the board may be tilted to enable the user to dive or resurface in the water, depending on the direction of tilt.
