Tuttle Box Fin M88 Supersport 45cm Select SML07521045

Description:

The M88 Supersport SL 45 cm is a Tuttle-box windsurfing fin engineered for freeride and freerace use, delivering an ideal balance of power, speed and maneuverability for experienced riders while remaining accessible to ambitious amateurs. Built from high-modulus carbon composite, the fin features an ultra-thin 8.8% profile (8.8 mm at a 10 cm chord) and a double-curved outline to minimize drag and enhance turning response. Select’s Active Flex technology pairs a rigid trailing edge with a dynamically responsive leading edge that absorbs lateral loads and twist, creating a very vertical lift and significantly reducing hull wetted surface. The result is superior top-end speed, improved tracking and more comfortable control at high speeds. The carbon construction provides immediate acceleration, precise feedback and long-term durability under heavy loads. Designed for Tuttle box installation and optimised for freeride/freerace boards in the 85–150 L range, the M88 Supersport SL is an uncomplicated upgrade for riders seeking race-capable performance.
