The Tomo Max Keel is Daniel Thomson’s groundbreaking twin fin, balancing the glide of a keel with the agility of a twin. With more surface area than any twin fin but less than a traditional keel, this hybrid template offers an ideal sweet spot for tight turns and controlled drive down the line. It’s engineered with a pivot keel shape and inside-to-flat foil, providing directional stability without locking the board, making it ideal for Tomo’s Revo Max surfboard. Compatible only with Futures single tab fin system.
