Deep Tuttle Box Fin M88 Superfast 40cm Select SML07512040

Deep Tuttle Box Fin M88 Superfast 40cm Select SML07512040

Description:

The M88 Superfast is Select’s most powerful, speed-oriented deep-tuttle fin, developed for aggressive speed and slalom sailing. Its core is built from high‑modulus carbon, allowing an ultra‑thin foil profile (8.8% thickness, e.g., 8.8 mm per 10 cm chord) that greatly reduces drag and improves top‑end speed. Select’s Active Flex design precisely balances flex and twist: a stiff trailing edge with a responsive leading edge absorbs lateral forces and produces a very vertical lift. The result is reduced wetted surface, sharper control at high speeds and improved stability through chop. Designed for use on speed and slalom boards in the 85–145 L range, the M88 Superfast delivers predictable performance for experienced sailors seeking maximum efficiency and durability. It mounts in a Deep Tuttle box and is optimized for boards and setups focused on outright velocity.

Key Features:

• High‑modulus carbon core for strength, stiffness and low weight
• Ultra‑thin foil profile (8.8% thickness) to minimize drag and maximize speed
