Appl. No.:

11/175532

Inventors:

Randal Richenberg - New Smyrna Beach FL, US
Christopher Coyle - New Smyrna Beach FL, US

International Classification:

B63B 1/00

US Classification:

441079000

Abstract:

A device for improving speed, control, and performance of water sports craft achieved by capturing lateral water flow and redirecting water flow longitudinally thereby increasing speed and control. The apparatus is designed to be attached to the underside of a water sports craft in the aft area by means of P.S.A. The invention consists of triangular shaped ridges or elevated ridges extending downward from the bottom surface of craft with a tapered leading entry point and exit point (FIGS. ) consisting of a smooth flexible plastic. The invention can be applied in various configurations and locations on the underside of a water vehicle to achieve desired effect. Invention requires installer to first clean surface that invention is to be applied to. A desirable configuration must first be obtained before removing the protective adhesive backing and then applying with firm pressure for proper bond.

Abstract:

Hydrodynamic ridge devices for mounting in pairs on the bottom of aquatic sports watercraft to form channels that capture lateral water flow and direct it longitudinally to enhance stability, speed, control, and performance of the watercraft. Each ridge device is a longitudinal body with a short flat vertical side, a wide flat top side extending horizontally from the top of the vertical side perpendicular thereto terminating in a convex generally arcuate outer edge, and a convex curved bottom side. The vertical side has an arcuate bottom edge that curves upwardly to a point at each end. The outer edge of the top side curves inwardly at each end to the points at the ends of the vertical side, and the curved bottom side curves upwardly and outwardly from the bottom of the vertical side to join the outer edge of the top side and the vertical side end points.
