ABSTRACT:
A toy speedboat apparatus is given that glides on a water surface. Three planing surfaces are arranged to give stable, repeatable coasting runs. The drag is independent of velocity and the planing surface angle relative to the water surface is optimized to give minimum drag. A propelling means converts stored energy to give a high speed initial velocity producing long gliding runs in excess of 100 feet.
