Power Box Fin M88 Superfast 42cm Select SML07510042

Power Box Fin M88 Superfast 42cm Select SML07510042

Description:

The Select M88 Superfast is a high-performance power box fin engineered for maximum speed and control on slalom and speed boards. Its core is constructed from high‑modulus carbon, allowing an ultra‑thin profile (8.8% thickness, i.e. 8.8 mm at a 10 cm chord) that dramatically reduces drag in all sailing directions. Select’s Active Flex concept pairs a rigid trailing edge with a responsive leading edge that absorbs lateral loads and produces controlled twist, creating a very vertical lift effect and reducing the hull’s wetted surface at high speed. The result is exceptional acceleration, top‑end velocity and precise tracking without sacrificing stability. Built for durability under extreme loads, the M88 Superfast is optimised for experienced riders seeking the ultimate advantage in speed and slalom racing. It fits standard power box systems and unlocks its full potential on appropriately sized boards.
