Deep Tuttle Box Fin M88 Superfast 36cm Select SML07512036

Deep Tuttle Box Fin M88 Superfast 36cm Select SML07512036

Description:

The M88 Superfast is Select’s most powerful and fastest fin, engineered specifically for high-speed slalom and speed conditions. Its core is constructed from high-modulus carbon, delivering an ultra-thin profile (8.8% thickness, equivalent to 8.8 mm for a 10 cm chord) that minimizes drag in all points of sail. Select’s Active Flex technology provides a precise balance of flex and twist: a rigid trailing edge combined with a compliant leading edge produces a very vertical lift and dynamic twist under load. This behavior reduces hull wetted surface and improves control, stability, and top-end speed, especially when pushed hard. The fin is optimized for experienced sailors on speed and slalom boards and unlocks maximum performance on 85–145 L boards. Precision manufacturing ensures consistent feel, excellent durability, and predictable behavior at high speeds. The M88 mounts in a Deep Tuttle box for secure, race-ready installation.
