Deep Tuttle Box Fin M88 Superfast 37cm Select SML07512037

Deep Tuttle Box Fin M88 Superfast 37cm Select SML07512037

Description: The M88 Superfast is Select's most powerful and speed-optimized hydrofoil fin, engineered for high-performance speed and slalom sailing. Its core structure is manufactured from high-modulus carbon, producing an ultra-thin profile (8.8% thickness — ~8.8 mm at a 10 cm chord) to minimize drag and maximize velocity in all sailing directions. Select's Active Flex concept combines a rigid trailing edge with a responsive leading edge that twists under lateral load, creating a strong vertical lift and reducing hull wetted surface for superior control. This precise balance of flex and twist improves stability and predictability at high speeds while delivering explosive acceleration and sustained top-end performance. Built to withstand the demands of aggressive planning and slalom use, the M88 Superfast offers durability and consistent feel through Select's advanced production processes. Designed to unlock its full potential in the hands of experienced sailors, it pairs with deep tuttle box mounts and is optimized for speed and slalom boards.
