ABSTRACT:
A floating aquatic device, e.g. toy, boat, etc, which is propelled by the wind and surf comprises a buoyant body hull and a flat, generally triangular, horizontal keel plate secured to the bottom of the hull in a vertical spaced relation. The body hull has a concave rear portion which is of greater height and width relative to the remainder of the hull and configured in a manner to capture sufficient water and/or wind forces to propel the toy through the water in which it is floating by the forces co-acting with the concave rear portion of the hull. The generally triangular keel is of sufficient weight to maintain said hull in an upright floating position and to stabilize the device. The concave rear portion of the hull is configured to bifurcate the water and/or wind forces co-acting with the rear portion to orient the forward end of the toy in a direction opposed to the forces. The concave rear portion of the hull directs a portion of the water forces from the curl of the wave downwardly onto the wide rear portion of the keel plate to skim the device through the water.
