Deep Tuttle Box Fin M88 Superfast 41cm Select SML07512041

Deep Tuttle Box Fin M88 Superfast 41cm Select SML07512041

Description:

The M88 Superfast is Select’s most powerful and fastest hydrofoil-style fin, engineered specifically for high-speed windsurfing on speed and slalom boards. Its core structure is built from high‑modulus carbon, allowing an ultra‑thin profile (8.8% thickness — 8.8 mm for a 10 cm chord) that minimizes drag and maximizes top‑end speed in all sailing directions. Select’s Active Flex concept delivers a precise balance of flex and twist: a stiff trailing edge with a compliant leading edge that absorbs lateral forces and generates a very vertical lift effect. This lift behavior reduces the hull’s wetted surface at speed, improving comfort, control and glide while keeping the board stable. The M88 is designed to withstand high loads and repeated use while maintaining performance, making it suitable for experienced sailors seeking maximum efficiency and speed. It mounts via a Deep Tuttle box and is optimized for use on speed and slalom boards sized roughly 85–145 liters.

Key Features:

• High‑modulus carbon construction for exceptional stiffness-to-weight ratio and low drag
• Ultra‑thin profile (8.8% thickness) for minimized hydrodynamic resistance
• Active Flex design: rigid trailing edge with a dynamically twisting leading edge
• Generates vertical lift to reduce hull wetted surface and increase top‑end speed
• Designed for high loads and sustained high‑speed use — durable construction
• Deep Tuttle Box compatibility for secure, standard windsurf mounting
• Optimized for speed and slalom performance on 85–145 L boards
• Ideal for experienced riders seeking maximum acceleration, stability and control
