Power Box Fin M88 Superfast 40cm Select SML07510040

Power Box Fin M88 Superfast 40cm Select SML07510040

Description:

The M88 Superfast is Select’s most powerful and fastest power-box hydrofoil fin, engineered for high-speed and slalom sailing. Its core structure is made from high‑modulus carbon, allowing an ultra‑thin 8.8% foil profile (8.8 mm at a 10 cm chord) that dramatically reduces drag in all sailing headings. Select’s Active Flex concept combines a rigid trailing edge with a leading edge that flexes and twists under load, producing a very vertical lift that lowers hull wetted surface and stabilizes the board at speed. The result is blistering acceleration, high top‑end velocity and superior control in gusty or flat conditions. Built for durability under extreme loads, the advanced carbon layup resists deformation while remaining lightweight. The M88 Superfast is optimized for experienced sailors on speed and slalom boards and installs into standard power‑box mounts. When paired with a properly sized 85–145 L board it unlocks its full performance potential.

Key Features:

• High‑modulus carbon composite core for exceptional stiffness-to-weight ratio
• Ultra‑thin 8.8% foil profile to minimize hydrodynamic drag
• Active Flex design: rigid trailing edge with a dynamically twisting leading edge
• Produces vertical lift that reduces hull wetted surface for higher speeds and stability
• Optimized for speed and slalom disciplines (boards 85–145 L)
• Power‑box compatible for secure, low‑play installation
• Durable carbon layup resists fatigue and deformation under high loads
• 40 cm span for maximum drive and control at top speeds
