Tuttle Box Fin M88 Supersport 38cm Select SML07521038

Tuttle Box Fin M88 Supersport 38cm — Select (SKU: SML07521038)

Description:
The M88 Supersport SL is Select Hydrofoils’ top-tier freeride/freerace tuttle-box fin, engineered to deliver exceptional speed, control, and maneuverability for experienced riders while remaining accessible to ambitious amateurs. Constructed from high-modulus carbon with an ultra-thin 8.8% profile, the fin minimizes drag in all points of sail for blistering straight-line performance. Its double-curved outline provides precise handling and responsive turning, making it ideal for aggressive carving and quick course corrections. Select’s Active Flex technology balances a rigid trailing edge with a dynamically compliant leading edge that absorbs lateral forces and twist, producing very vertical lift and reducing hull wetted surface. The result is a stable, comfortable ride at high speed with improved upwind drive and reduced hull resistance. Designed specifically for use with tuttle box mounts and optimized for freeride/freerace boards, the M88 gives a measurable performance advantage in competitive and high-speed recreational sailing.

Key Features: - High-modulus carbon construction for excellent stiffness-to-weight ratio and long-term durability.
- Ultra-thin profile (8.8% thickness; 8.8 mm per 10 cm chord) to reduce drag and improve top-end speed.
- Active Flex technology: rigid trailing edge with a compliant leading edge for controlled twist and vertical lift.
- Double-curved outline for enhanced maneuverability and precise turning response.
- Tuned for freeride and freerace boards (recommended 85–150 L) to boost acceleration and stability.
- Tuttle box mount compatibility for secure, direct attachment to standard tuttle-box boards.
- User-friendly design that balances high-performance characteristics with accessibility for skilled amateurs.
- Reduced wetted surface area at speed for improved efficiency and lower hull resistance.
