Tuttle Box Fin M88 Supersport 44cm Select SML07521044

Description:

The Select M88 Supersport SL is a high-performance tuttle box fin engineered for freeride and freerace windsurfing boards, delivering a blend of speed, drive and responsive handling. Crafted from high-modulus carbon, the blade features an ultra-thin profile (8.8% thickness) that minimizes drag and maximizes top-end speed in all points of sail. Its double-curved outline and precision layup provide exceptional maneuverability and a lively, predictable feel through turns and gusts. Select’s Active Flex technology balances a stiff trailing edge with a compliant leading edge, producing vertical lift that reduces hull wetted area and boosts stability at high speeds. Durable carbon construction and refined shaping make the M88 comfortable for long sessions while remaining accessible to ambitious amateurs and seasoned racers. Designed for tuttle box mounting, this fin pairs best with freeride/freerace boards in the 85–150 L range for an immediate performance upgrade.
