ABSTRACT:
A guidance pad, made from flexible plastic material and configured with an array of parallel guidance ridges on the bottom side, can be retrofitted onto the bottom side of an aquatic sports device such as a surfboard so that the ridges, running fore-and-aft, enhance lateral stability by guiding water flow through the channels formed between the ridges. In a preferred embodiment, five equally-spaced ridges having a V-shaped cross-section are molded integrally on the bottom side of a generally rectangular thin flexible pad whose flat top surface is provided with a layer of self-adhesive material retained by a peel-off backing. To install the guidance pad, the backing is peeled off to expose the adhesive material and the top surface of the pad is attached onto the bottom of the surfboard just forward of the fin, for which a cutaway region is provided at the aft edge of the pad. The hydro-dynamic effects, e.g. lateral resistance, provided by the plural shallow ridges of the guidance pad of this invention combine synergistically with the hydro-dynamic effects of the deeper, shorter fixed fin(s) and overall streamlined profile to provide the surfer with enhanced overall surfing performance, including greater control and maneuverability, and faster response time on turns.
