Abstract
Abstract An inflatable hydroplane apparatus uses a pneumatic vehicle innertube with a flexible fabric cover including an annular flexible fabric positioned partly covering said innertube and forming a smooth bottom therefor. A handle strap is stitched to the cover for the rider to hold on to and a tow rope attaching strap is stitched to the bottom portion of the cover for attaching a tow rope from a boat for pulling the hydroplane. The innertube is inflated in the cover to form the hydroplane and deflated for storage.
