Windsurf fin JP-Australia Side Wave RTM CARBON Fin SB

These side wave fins are designed as rail-mounted, supplementary fins to increase grip and control during extreme maneuvers. When the rider rails up hard and the tail begins to lift—such as in top turns that become lip slides or in very aggressive bottom turns—center or twin fins can lose contact with the water. The side fins remain engaged, keeping the board tracking and preventing loss of control.

The fins feature a balanced outline and a straight rake curve, producing a direct, responsive feel and enabling sharper, more radical turns. They improve confidence in aggressive riding and help you exit critical maneuvers more cleanly. Important: these side fins are made for Slot Box (SB) mounting systems.
