Tuttle Box Fin M88 Superfast 33cm Select SML07511033

Tuttle Box Fin M88 Superfast 33cm Select SML07511033

Description: The Select M88 Superfast is a high-performance Tuttle-box fin engineered for top-end speed and precision on speed and slalom windsurf boards. Its core structure is built from high-modulus carbon composite, producing an ultra-thin foil profile (8.8% thickness) that minimizes drag in all points of sail for exceptional velocity. Select's Active Flex concept balances a rigid trailing edge with a compliant leading edge that twists under lateral loads to generate a very vertical lift, reducing hull wetted surface and improving stability at high speed. The result is a fin that delivers sharper acceleration, higher top-end speed and predictable control when pushing limits. Designed for durability under repetitive loads, the carbon construction resists fatigue while keeping weight low for quick response. The M88 unlocks peak performance on speed and slalom boards between roughly 85–145 liters and mounts cleanly into a Tuttle box for secure, low-drag installation.

Key Features: - High-modulus carbon composite construction for stiffness, light weight and longevity
- Ultra-thin 8.8% foil profile to minimize hydrodynamic drag and improve straight-line speed
- Active Flex design: rigid trailing edge with a dynamically twisting leading edge for vertical lift and reduced wetted area
- Optimized flex/twist balance for stable, predictable handling at high speeds
- Tuttle-box compatible for secure, low-profile mounting on speed/slalom boards
- Engineered for boards in the 85–145 L range—ideal for speed runs and slalom courses
- Low drag profile enhances acceleration and top-end performance while reducing hull vibration
- Robust carbon layup resists fatigue from repeated high-load use

Compatibility: Tuttle box mounting; optimized for speed and slalom boards 85–145 L

Recommended Use: Ideal for experienced and advanced windsurfers or competitive sailors seeking maximum speed and control on slalom and speed courses. Best used on speed and slalom boards in flat to moderately choppy open-water conditions where minimizing hull drag and maximizing top-end velocity are priorities. Pair with a board fitted with a Tuttle box and a properly matched fin box hardware kit; consider reinforced footstraps and a well-tuned rig to exploit the fin’s high-speed capabilities.
