Deep Tuttle Box Fin M88 Superfast 46cm Select SML07512046

Deep Tuttle Box Fin M88 Superfast 46cm Select SML07512046

Description:

The M88 Superfast is Select’s most powerful and speed-oriented deep-tuttle fin, engineered for high-performance speed and slalom windsurfing. Its core structure is built from high-modulus carbon to produce an ultra-thin profile (8.8% thickness), minimizing drag in all sailing directions and maximizing top-end speed. Select’s Active Flex design balances flex and twist precisely — a rigid trailing edge paired with a compliant leading edge — producing a very vertical lift that trims wetted hull surface and stabilizes the board at pace. The result is exceptional acceleration, direct steering feedback and confident control in high-speed runs. Durable carbon construction and optimized shape deliver consistent performance session after session for experienced sailors. Designed to mount in a Deep Tuttle box and to perform best on speed and slalom boards in the 85–145 L range.
