Tuttle Box Fin M88 Superfast 31cm Select SML07511031

Tuttle Box Fin M88 Superfast 31cm Select SML07511031

Description:

The M88 Superfast is Select's most powerful and speed-oriented hydrofoil fin, engineered for high-performance slalom and speed sailing. Its core structure is constructed from high-modulus carbon to produce an ultra-thin airfoil profile (8.8% thickness), minimizing drag and maximizing velocity across all points of sail. Select's Active Flex concept pairs a stiff trailing edge with a dynamically twisting leading edge so the fin generates a highly vertical lift while reducing the hull’s wetted surface area. This controlled flex and twist deliver exceptional stability, comfort, and control at high speeds, allowing riders to maintain predictable behaviour even in demanding conditions. Durability is enhanced by the carbon construction and precision manufacturing, making the fin suitable for repeated use under race or training loads. Designed to unlock maximum performance on speed and slalom boards between 85 and 145 liters, the M88 Superfast is aimed at experienced sailors who demand top-end speed and efficient lift. Compatibility with standard tuttle box mounts makes it straightforward to fit to most slalom/speed boards.

Recommended Use:

Ideal for advanced and professional windsurfers focused on slalom and speed sailing, the M88 Superfast excels on boards sized roughly 85–145 liters. Best performed in open-water, flat-to-chop conditions where high speeds are attainable and reduced drag yields the most benefit. Fit into a standard tuttle box and pair with a high-performance slalom/speed board; no special accessories required beyond regular fin screws and a compatible tuttle mounting system.
