Grennan (S, M, L) - Apex (Futures (Single Tab) / Small)

"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. The Grennan fins are part of the Specialty family Small Front Base: 3.54" Height: 4.25" Area : 11.09 in² Foil : Flat Center Base: 3.54" Height: 4.25" Area : 11.09 in² Foil : 50/50 Medium Front Base : 3.82" Height : 4.60" Area : 12.87 in² Foil : Flat Center Base : 3.82" Height : 4.60" Area : 12.87 in² Foil : 50/50 Large Front Base : 3.84" Height : 4.60" Area : 14.11 in² Foil : Flat Center Base : 3.84" Height : 4.60" Area : 14.11 in² Foil : 50/50 Part of our Apex G10 Construction; made with a solid piece of precision foiled G10 fiberglass for the ultimate in performance and durability.
