Tuttle Box Fin M88 Superfast 36cm Select SML07511036

Tuttle Box Fin M88 Superfast 36cm Select SML07511036

Description:

The M88 Superfast is Select’s most powerful and speed-oriented fin, engineered for high-performance speed and slalom boards. Its core is constructed from high-modulus carbon composite, producing an ultra-thin profile (8.8% thickness) that minimizes drag and maximizes velocity through the water. The fin uses Select’s Active Flex concept: a rigid trailing edge with a dynamically responsive leading edge that absorbs lateral forces and produces a very vertical lift vector. This tailored flex-and-twist balance reduces wetted hull area, improving control and comfort at high speeds while maintaining stability. Designed for advanced sailors, the M88 delivers crisp acceleration, sustained top-end speed and precise tracking in intense racing or speed runs. The fin is supplied in a Tuttle box mounting format for secure installation in compatible boards.
