Power Box Fin M88 Superfast 39cm Select SML07510039

Power Box Fin M88 Superfast 39cm Select SML07510039

Description: The M88 Superfast is Select’s highest-performance power box fin, engineered for maximum speed and control in slalom and speed windsurfing. Its core structure is made from high‑modulus carbon, producing an ultra‑thin profile (8.8% thickness, i.e., 8.8 mm for a 10 cm chord) that dramatically reduces drag in all sailing directions. Select’s Active Flex concept balances a rigid trailing edge with a compliant leading edge so the fin twists under load to create a vertical lift effect, lowering hull wetted surface and increasing top‑end speed. This engineered flex pattern gives exceptional stability and control at high speeds while maintaining responsive feedback for experienced sailors. Built for durability and repeatable performance, the M88 Superfast unlocks its full potential on speed and slalom boards in the 85–145 L range and is intended for sailors who demand precision and raw pace.
