Power Box Fin M88 Superfast 38cm Select SML07510038

Power Box Fin M88 Superfast 38cm Select SML07510038

Description:

The M88 Superfast is Select’s most powerful, speed-oriented Power Box fin, engineered to deliver maximum top-end performance for experienced sailors. Its core structure is built from high-modulus carbon composite, producing an ultra-thin profile (8.8% thickness — 8.8 mm per 10 cm chord) that minimizes drag in all points of sail. The fin uses Select’s Active Flex concept: a stiff trailing edge paired with a leading edge engineered to absorb lateral loads and twist, creating a highly vertical lift characteristic. This dynamic flex/twist balance reduces hull wetted surface and improves stability and control at high speed. The result is faster acceleration, higher top speed and more comfortable handling in planing conditions. Designed specifically for speed and slalom boards, the M88 unlocks performance on boards in the 85–145 L range and fits standard Power Box installations.

Key Features:

• High-modulus carbon composite construction for exceptional stiffness-to-weight ratio and durability
• Ultra-thin 8.8% foil profile to minimize drag and maximize speed
• Active Flex design: rigid trailing edge with adaptive leading-edge twist for vertical lift and precise control
• Optimized for speed and slalom disciplines, improving acceleration and top-end velocity
• Reduces hull wetted surface for lower resistance and more comfortable high-speed riding
• Power Box compatible mounting for secure, low-drag installation
• Ideal for experienced sailors using 85–145 L speed/slalom boards
• Robust construction for repeated high-load, high-speed use

Recommended Use:

Best suited for advanced and professional sailors focused on speed or slalom racing who ride planing boards. Ideal for use on speed and slalom boards between roughly 85–145 liters and in conditions where high speeds are achievable (strong winds, planing sea states, flat to moderately choppy water). Use with a Power Box-compatible board setup; check box compatibility before purchase. Pair with a board tuned for speed (trim, footstrap setup and rig tuning) to fully exploit the fin’s performance characteristics.
