Tuttle Box Fin M88 Supersport 47cm Select SML07521047

Description:

The M88 Supersport SL is Select Hydrofoils' high-performance freeride/freerace fin engineered for riders who demand speed, control and agility. Constructed from high-modulus carbon with an ultra-thin 8.8% profile, the fin minimizes drag across all points of sail while maintaining exceptional stiffness and durability. Its double-curved outline delivers outstanding maneuverability and precise tracking, making sharp turns feel responsive and controlled. Select’s Active Flex Technology balances a rigid trailing edge with a dynamically compliant leading edge, producing very vertical lift and significantly reducing hull wetted surface for higher top speeds. Despite its racetrack pedigree, the M88 remains accessible to skilled amateur riders, providing predictable behavior and confidence at high speeds. Designed for Tuttle-box installation and matched to freeride/freerace boards between 85–150 liters, it’s an immediate performance upgrade for competitive and performance-oriented recreational sailors.
