Power Box Fin M88 Superfast 41cm Select SML07510041

Power Box Fin M88 Superfast 41cm Select SML07510041

Description:

The Select M88 Superfast is a high-performance Power Box fin engineered for maximum speed and control on speed and slalom boards. Its core structure is built from high‑modulus carbon, allowing an ultra‑thin profile (8.8% thickness — 8.8 mm per 10 cm chord) that dramatically reduces drag in all sailing orientations. Select’s Active Flex concept gives a stiff trailing edge with a compliant leading edge that twists under lateral load to produce a very vertical lift, lowering hull wetted surface and improving straight-line stability. The fin’s balance of flex and twist delivers confident, predictable handling at high speeds while preserving durability through advanced carbon construction. Designed for use on 85–145 L boards and fitted to Power Box mounts, the M88 Superfast is tailored for experienced sailors chasing top-end speed and responsiveness.
