Power Box Fin M88 Supersport 37cm Select SML07520037

Power Box Fin M88 Supersport 37cm Select SML07520037

Description:

The M88 Supersport SL is Select Hydrofoils' premier freeride/freerace power box fin, engineered to deliver a high-performance balance of speed, control and accessibility for experienced riders and ambitious amateurs. Constructed from high‑modulus carbon, the fin features an ultra‑thin 8.8% profile (8.8 mm at a 10 cm chord) that minimizes drag and unlocks exceptional straight‑line speed. A double‑curved outline provides outstanding maneuverability and confident turning response at high speeds. Select’s Active Flex technology precisely balances a rigid trailing edge with a dynamically responsive leading edge, generating vertical lift that reduces hull wetted surface and improves stability. The result is a fin that accelerates quickly, holds a clean line through chop and gusts, and remains forgiving enough for progressing riders. Designed for Power Box installation, the M88 Supersport SL is optimized for freeride and freerace boards in the 85–150 L range.
