Abstract: A personal buoyancy boat device for use in water sports games employs an inflatable inner tube retained within a housing of generally torroidal shape. A buoyant deck panel is disposed above the housing and secures two valves emergent from the tube, a first valve for deflation, and a second valve for inflation. A water-collecting target assembly is disposed above the deflation valve. When the target assembly fills with water, its added weight causes depression of the deflation valve, causing the boat device to ride lower in the water. The buoyant deck panel prevents the total submersion of the boat device.
