Jeff Grennan has been working on the design of his templates for years.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.
