Tuttle Box Fin M88 Supersport 42cm Select SML07521042

Description:

The M88 Supersport SL is a high-performance tuttle-box fin engineered for freeride and freerace sailing, delivering a refined balance of speed, power and user-friendly handling. Built from high-modulus carbon with an ultra-thin 8.8% profile, the blade cuts drag and maintains top-end velocity in all points of sail. Select's Active Flex technology pairs a stiff trailing edge with a dynamically responsive leading edge to produce vertical lift, reduced hull wetted area and exceptional control at high speeds. The double-curved outline enhances maneuverability and responsiveness during transitions and carving. Designed to boost the performance of boards between 85–150 L, the M88 gives experienced riders the extra drive they need while remaining accessible to ambitious amateur racers.
