Flying Diamonds of California Sea Monnster Pivot Josh's go-to fin. The wide surface area creates hold and stability from the nose, while the slender but stiff foil allows for quick adjustments from the tail and control through turns. Designed to hang ten through critical sections and whitewater without sliding out, this fin offers ultimate tip control--ideal for anyone trying to steer from the nose and hang ten as long as possible. Josh rides the 10" Sea Monnster in his 9'4" Sprout. He recommends the 11" for boards 9'10" and bigger or for surfers who ride larger waves/ put a little more weight into their turns.
