Tuttle Box Fin M88 Supersport 39cm Select SML07521039

Description:

The M88 Supersport 39cm is a high-performance Tuttle box fin engineered for freeride and freerace windsurfing, delivering an exceptional balance of speed, power and control. Constructed from high-modulus carbon, the blade features an ultra-thin 8.8% profile that minimizes drag and slices efficiently through all points of sail. Select’s Active Flex technology combines a stiff trailing edge with a dynamically responsive leading edge to produce vertical lift, reduce hull wetted surface and stabilize the board at high speeds. A double-curved outline enhances maneuverability and allows precise rail-to-rail transitions without sacrificing forward drive. Despite its race-oriented performance, the M88 remains accessible to experienced amateurs thanks to its predictable flex and user-friendly feel. Designed for use with freeride and freerace boards in the 85–150 L range, it provides a clear performance upgrade for riders seeking faster planing and tighter turns.
