Tuttle Box Fin M88 Supersport 31cm Select SML07521031

Tuttle Box Fin M88 Supersport 31cm Select SML07521031

Description:

The Select M88 Supersport is a high-performance Tuttle Box fin engineered for freeride and freerace windsurfing boards, delivering exceptional speed, control, and maneuverability. Constructed from high-modulus carbon, the fin features an ultra-thin profile (8.8% thickness) and a double-curved outline that minimizes drag while maintaining agile handling. Select’s Active Flex technology balances flex and twist by a stiff trailing edge and a dynamic leading edge, producing a very vertical lift and greatly reducing hull wetted surface at speed. This combination yields superb top-end velocity and stability without sacrificing accessibility for intermediate riders. Durable carbon construction ensures long-term stiffness and responsiveness under repeated load, making the M88 ideal for sustained high-speed use. The fin is supplied in a Tuttle Box configuration for direct compatibility with Tuttle-equipped freeride and freerace boards.
