Power Box Fin M88 Supersport 39cm Select SML07520039

Description: The Power Box Fin M88 Supersport is Select Hydrofoils' premier freeride/freerace fin designed to deliver exceptional speed, power and responsiveness for advanced riders while remaining accessible to ambitious amateurs. Constructed from high-modulus carbon, the M88 features an ultra-thin 8.8% profile that minimizes drag in all sailing directions for sustained top-end performance. Its double-curved outline offers outstanding maneuverability and agile handling through carved turns and high-speed transitions. Select’s Active Flex technology balances a rigid trailing edge with a dynamically responsive leading edge to produce very vertical lift, reducing hull wetted surface and improving straight-line stability. The slim profile and optimized flex pattern also increase comfort and control at high speeds by dampening lateral forces and unwanted twist. Designed for use with freeride and freerace boards, the M88 provides a clear performance advantage for riders seeking reduced drag and sharper, more predictable handling.
