Power Box Fin M88 Superfast 45cm Select SML07510045

Power Box Fin M88 Superfast 45cm Select SML07510045

Description:

The M88 Superfast is Select’s most powerful and fastest power box fin, engineered specifically for high-speed slalom and speed sailing. Its core structure is built from high-modulus carbon, enabling an ultra-thin profile of just 8.8% thickness (8.8 mm at a 10 cm chord) to minimize drag and maximize straight-line speed. The fin uses Select’s Active Flex concept: a rigid trailing edge combined with a leading edge that flexes and twists to absorb lateral forces, producing very vertical lift and markedly reducing hull wetted surface. This balance of stiffness and controlled flex gives precise tracking, exceptional stability at high speeds, and outstanding acceleration out of turns. Designed for use on speed and slalom boards from about 85 to 145 liters, the M88 Superfast rewards experienced sailors seeking top-end performance and confidence in challenging conditions. The fin fits standard power box mounts and pares well with performance slalom or speed rigs for competitive sailing or record attempts.

Key Features:

• High-modulus carbon construction for maximum stiffness-to-weight ratio and durability
• Ultra-thin foil profile (8.8% thickness) for reduced drag and improved top speed
