Deep Tuttle Box Fin M88 Superfast 31cm Select SML07512031

Deep Tuttle Box Fin M88 Superfast 31cm — Select
SKU: SML07512031

Description:

The M88 Superfast is Select’s most powerful, speed-oriented deep-tuttle fin, engineered specifically for high‑performance speed and slalom windsurfing. Its core is manufactured from high‑modulus carbon, producing an ultra‑thin, highly streamlined profile (8.8% thickness — 8.8 mm at a 10 cm chord) that minimizes drag in all sailing directions. Select’s Active Flex concept delivers a precise balance of flex and twist: a rigid trailing edge with a responsive leading edge that absorbs lateral loads and twists dynamically to create a very vertical lift. This reduces wetted hull surface and delivers exceptional control, stability and comfort at high speeds. Built for boards in the 85–145 L range, the M88 Superfast unlocks maximum top‑end performance for experienced sailors seeking aggressive acceleration and reduced resistance. The fin mounts in a standard Deep Tuttle box and is designed to hold up under repeated high‑load use.

Key Features:

• High‑modulus carbon core for maximum stiffness-to-weight ratio and durability
• Ultra‑thin hydrodynamic profile (8.8% thickness) for minimal drag and improved top speed
• Active Flex geometry: rigid trailing edge with a torsionally active leading edge for dynamic lift control
• Very vertical lift characteristic reduces wetted surface and hull drag at planing speeds
• Optimized for speed and slalom boards between 85–145 liters
• Deep Tuttle box compatibility for secure, high‑load mounting
• Engineered for experienced riders seeking high‑speed stability and precise tracking
• Durable composite construction designed to withstand repeated high‑stress conditions
