Tuttle Box Fin M88 Superfast 37cm Select SML07511037

Tuttle Box Fin M88 Superfast 37cm Select SML07511037

Description:

The Select M88 Superfast is a high-performance tuttle-box fin engineered for maximum speed and control on slalom and speed windsurfing boards. Its core is constructed from high-modulus carbon, producing an ultra-thin foil with just 8.8% thickness (8.8 mm for a 10 cm chord) to minimize drag through all points of sail. Select’s Active Flex concept blends a rigid trailing edge with a responsive leading edge that twists under load, producing a very vertical lift that reduces hull wetted surface and enhances top-end speed. The precise balance of stiffness and twist gives stable, predictable handling at high speeds while improving acceleration and straight-line tracking. Built for durability and repeated high-load use, the M88 Superfast is optimized for experienced sailors seeking performance gains on 85–145 L slalom and speed boards. It mounts in a standard tuttle box and unlocks its full potential when paired with performance-oriented boards and setups.
