摘要： A water sport training device is disclosed comprising, in one embodiment, a raft having a distal nose portion and a proximal rear portion. A relatively rigid platform is positioned within the raft and configured to provide a stable surface for the person during use of the device. A tow rope attachment means is 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 of the raft, below a nose portion mid-plane. The device is configured such that a back half of the device has a center buoyancy sufficient for providing a stable surface to support the weight of a person while floating on water both at standstill and as being pulled through the water as by a boat.

摘要： A water sport training device is disclosed comprising, in one embodiment, a raft having a distal nose portion and a proximal rear portion. The rear portion provides a pair of substantially spaced apart lateral pontoons and a first web spanning the space therebetween. A relatively rigid platform is positionable within the raft, substantially adjacent the first web. A buoyant seat portion is positioned substantially on a back half of the device between the pontoons and adjacent the platform. A tow rope attachment means is secured to the raft for selectively towing the device over a body of water. The device is configured such that a back half of the device has a center buoyancy sufficient for providing a stable surface to support the weight of a person while floating on water both at standstill and as being pulled through the water as by a boat.
