ABSTRACT:
An aerodynamic and hydromechanical hydroplaning disc with a solid unitary body comprised of aggregated material. The disc is heavier than the water it displaces and non-floating. The peripheral edge of the disc is formed with a top to bottom curvature having a relatively smaller radius at the top than at the bottom of the disc which reduces air resistance and has a shape to increase the planing capacities as the disc strikes the water. The texture of the material is also significant in combination with circular or polygonal edge formations to enhance the aerodynamic, hydrodynamic and hydromechanical characteristics.
