Tuttle Box Fin M88 Superfast 39cm Select SML07511039

Tuttle Box Fin M88 Superfast 39cm Select SML07511039

Description:

The Select M88 Superfast is a high-performance tuttle box fin engineered for maximum speed and lift in slalom and speed sailing. Its core structure is built from high‑modulus carbon, allowing an ultra‑thin profile (8.8% thickness — 8.8 mm per 10 cm chord) that minimizes drag through all points of sail. Select’s Active Flex concept balances controlled flex and twist: a stiff trailing edge with a dynamic leading edge that absorbs lateral forces to create a very vertical lift effect. This design reduces hull wetted surface, improving comfort, stability and control at high speeds while keeping the board planted and responsive. The fin is optimized for experienced sailors using speed and slalom boards between ~85 and 145 liters and is intended to be mounted in a standard tuttle box. Precision carbon construction also provides durability and consistent behavior under heavy loads, making it suitable for competitive use.
