Deep Tuttle Box Fin M88 Superfast 39cm Select SML07512039

Deep Tuttle Box Fin M88 Superfast 39cm — Select (SML07512039)

Description: The M88 Superfast is Select’s most powerful and speed-oriented deep-tuttle fin, engineered specifically for high-speed and slalom windsurfing. Its core structure is crafted from high-modulus carbon, producing an ultra-thin 8.8% profile that minimizes drag and slices through water with exceptional efficiency. Select’s Active Flex concept provides a precise balance of flex and twist: a stiff trailing edge with a dynamically responsive leading edge creates a very vertical lift and significantly reduces hull wetted surface. This combination yields outstanding top-end speed, improved control and stability at high velocity, and predictable behavior in gusty conditions. Built for durability and performance, the M88 Superfast unlocks maximum potential when paired with speed and slalom boards in the 85–145 L range. The fin mounts in a Deep Tuttle box and is intended for experienced sailors seeking race-level performance.
