Tuttle Box Fin M88 Supersport 43cm Select SML07521043

Description: The M88 Supersport SL is Select Hydrofoils' high-performance freeride/freerace fin designed to deliver exceptional speed, control and responsiveness for advanced and ambitious riders. Constructed from high-modulus carbon, the fin features an ultra-thin 8.8% profile that minimizes drag through all points of sail while maintaining outstanding structural stiffness. Select’s Active Flex technology balances a stiff trailing edge with a dynamically compliant leading edge, producing vertical lift that reduces hull wetted surface and improves top-end stability. Its double-curved outline enhances maneuverability and quick rail-to-rail response without sacrificing straight-line speed. Though tuned for experienced riders and racers, the M88 remains forgiving enough for enthusiastic amateurs stepping up their performance. The fin is built for Tuttle box mounting and pairs ideally with freeride and freerace boards in the 85–150 L range.
