Fin M88 Supersport 46 Deep Tuttle Box

The M88 Supersport SLs are Select Hydrofoils' premier freeride sport fins, delivering a perfect combination of power, speed, and accessibility for seasoned riders. While exceptionally fast, these fins remain user-friendly for amateur riders. The double-curved outline ensures outstanding maneuverability.

Crafted from high-modulus carbon, the M88 Supersport SLs boast an ultra-thin profile of just 8.8% thickness (8.8 mm for a 10 cm chord). This sleek design minimizes drag in all sailing directions, enabling extraordinary speed and performance.
**Active Flex Technology for Superior Control**

One of the standout features of the M88 series is its precise balance of flex and twist, referred to as Active Flex. Select's advanced production technology ensures the trailing edge remains rigid while allowing the leading edge to dynamically absorb lateral forces and twist. This creates a very vertical lift, significantly reducing the wetted surface area of the hull and offering unmatched comfort and control at high speeds.

Designed for use with freeride and freerace boards ranging from 85 to 150 liters, the M88 Supersport SL fins deliver a substantial performance boost for seasoned riders and amateur racers alike.
