Patent ID: 8025541

Claim:
A water sport training device for supporting the weight of a person floating on water both at standstill and as being pulled through the water as by a boat, the device comprising: a substantially U-shaped raft having a distal nose portion and a proximal rear portion, the nose portion defining a nose portion mid-plane substantially midway through a horizontal thickness of the nose portion; the rear portion comprising a pair of spaced apart, substantially parallel lateral pontoons; a relatively rigid platform positioned within the raft and configured for providing a substantially stable surface for the person during use of the device; and a tow rope attachment means secured to the raft for selectively towing the device over a body of water, the attachment means comprising at least one tow rope attachment point located on the nose portion below the nose portion mid-plane; whereby the rear portion and platform are configured for allowing water that ma enter the raft during use to freely exit the raft proximal a rear side thereof, such that a back half of the device is capable of substantially maintaining a center buoyancy, as measured by the weight of the volume of water displaced thereby, of greater than at least fifty percent of the weight of the person.
