Abstract
A gliding or flying hydrodynamic disc designed for recreational use under water. The disc is circular and about 12 inches or 300 mm in diameter, and about ½ inch or 1.198 centimeters high. Circular grooves on the surface of the disc provide a grip surface so that the user can adequately maintain control of the disc under water. The weight of the disc is determined to allow the device to generally maintain equilibrium while under water. The shape and the materials are crafted to provide minimum drag. The top and bottom of the device are symmetrical to minimize drag-inducing lift effects. A soft outer edge surface provides a good grip on the device and for safety in pool and dive use. The disc can also be used as a dive plane or to change course by holding it out in front while the user is swimming.
