Deep Tuttle Box Fin M88 Superfast 42cm Select SML07512042

Deep Tuttle Box Fin M88 Superfast 42cm Select SML07512042

Description:

The Select M88 Superfast is a high-performance Deep Tuttle Box fin engineered for maximum speed and control on slalom and speed boards. Its core is built from high-modulus carbon, giving an ultra-thin 8.8% section that minimizes drag and improves acceleration across all points of sail. Select’s Active Flex concept balances a rigid trailing edge with a responsive leading edge that twists to absorb lateral loads, producing a very vertical lift and significantly reducing hull wetted surface at high speeds. The result is superior top-end speed, stable tracking and confident control in planing conditions. Optimized for experienced riders, the M88 unlocks peak performance on speed and slalom boards between 85 and 145 liters when fitted into a Deep Tuttle Box. Durable carbon construction also provides consistent response and longevity under heavy use. Ideal for racers and advanced sailors seeking the fastest, most efficient fin for flat to choppy high-speed conditions.

Key Features:

• High-modulus carbon composite core for an ultra-light, stiff structure
• Ultra-thin profile: 8.8% thickness (8.8 mm at 10 cm chord) to reduce drag
• Active Flex design: stiff trailing edge with a twisting leading edge for dynamic lift control
• Very vertical lift vector reduces hull wetted surface and improves top speed
• Optimized stiffness-to-flex ratio for stability at speed and precise handling
• Specifically tuned for speed and slalom boards (85–145 L)
• Deep Tuttle Box compatible mounting for secure, race-ready installation
• Durable carbon finish engineered for longevity under high loads
