Power Box Fin M88 Superfast 46cm Select SML07510046

Power Box Fin M88 Superfast 46cm Select SML07510046

Description:

The Power Box M88 Superfast is Select’s most powerful and fastest hydrofoil-style fin, engineered specifically for high-speed and slalom windsurfing on speed-oriented boards. Its core structure is built from high‑modulus carbon, allowing an ultra‑thin profile of just 8.8% thickness (8.8 mm at a 10 cm chord) to minimize drag and maximize top‑end speed. Select’s Active Flex concept balances controlled twist and flex — a rigid trailing edge with a responsive leading edge — producing a vertical lift effect that reduces hull wetted surface and improves tracking at speed. The result is exceptional acceleration, stability and confident control in aggressive planing and downwind runs. Designed for power box mounting, the M88 Superfast is optimized for experienced sailors using speed and slalom boards in the 85–145 L range, delivering precise feedback and efficient energy transfer. Durable carbon construction ensures longevity under heavy use while keeping weight low for improved responsiveness.
