Over the last year we’ve been working with him to add a high performance foil in order to increase the flow and speed of his fins. Jeff’s idea was to pair a narrow base with increased rake in order to decrease drag while retaining control down the line and through turns. And boy was he right; his template has become a favorite in the San Diego glider scene and is used by the likes of Skip Fry and Bob Mitsven as well a tons of others.Part of our Apex G10 Construction; made with a solid piece of precision foiled G10 fiberglass for the ultimate in performance and durability. The combination of highly durable material and precision foiling yield a fin that is stronger and has a more ideal flex pattern than your traditional honeycomb or composite fins.
