Water sport training device

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 rear portion comprising a pair of spaced apart, substantially parallel lateral pontoons;
• a relatively rigid platform removably engaged with the raft and configured for providing a substantially stable surface for the person during use of the device;
• a buoyant seat portion positioned substantially on a back half of the device between the pontoons and adjacent to the platform, the seat portion configured for at least partially contributing to a center buoyancy of the back half of the device, as measured by the weight of the volume of water displaced thereby;
• 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;
• whereby the rear portion and platform are configured for allowing water that may enter the raft during use to freely exit the raft proximal a rear side thereof, such that the back half of the device is capable of substantially maintaining a center buoyancy of greater than at least fifty percent of the weight of the person.

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 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;
• a seat portion positioned substantially on a back half of the device, wherein the back half of the device has 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 supported by the device, and further wherein at least the rear portion and seat portion are configured for providing the entire center buoyancy of the back half of the device;
• a strap assembly having an at least one elongate upper strap portion, engaged proximally with the nose portion of the raft and distally with an at least one elongate lower strap portion, the at least one lower strap portion engaged proximally with the nose portion below the nose portion mid-plane;
• the at least one lower strap portion being at least twice as long as the at least one upper strap portion;
• and
• a first web installed proximal the seat portion and configured to provide an upper surface on which the person may stand.

• a substantially U-shaped raft having a distal nose portion and a proximal rear portion, the rear portion comprising a pair of spaced apart, substantially parallel lateral pontoons;
• a first web spanning a perimeter of the raft;
• a second web spanning the perimeter of the raft, offset from the first web, the first and second webs cooperating to define a platform pocket therebetween;
• a buoyant seat portion positioned substantially on a back half of the device between the pontoons and adjacent to the first and second webs, the seat portion configured for at least partially contributing to a center buoyancy of the back half of the device, as measured by the weight of the volume of water displaced thereby;
• and
• a relatively rigid platform selectively positionable within the platform pocket and configured for providing provide a substantially stable surface for the person during use of the device, the platform defining a cutout portion sized and configured for allowing the seat portion to float on the water during use of the device;
• whereby the device is configured for allowing water that may enter the raft during use to freely exit the raft proximal a rear side thereof, such that the back half of the device is capable of substantially maintaining a center buoyancy of greater than at least fifty percent of the weight of the person.

• and
• a first web installed within the raft, spanning a perimeter thereof, and configured to be selectively operable with a removably engagable, relatively rigid platform capable of providing a substantially stable surface for the person during use of the device, the platform being selected from one of a substantially U-shaped ski training board, a body board, an at least one water ski, a kneeboard, a wakeboard, and a surfboard.
