Tuttle Box Fin M88 Superfast 45cm Select SML07511045

Tuttle Box Fin M88 Superfast 45cm Select SML07511045

Description:

The Select M88 Superfast is a high-performance Tuttle-box fin engineered for speed-focused windsurfing on slalom and speed boards. Its internal core is constructed from high-modulus carbon to achieve an ultra-thin profile (8.8% thickness, e.g. 8.8 mm at a 10 cm chord), minimizing drag in all sailing directions and maximizing top-end velocity. Select’s Active Flex concept precisely balances flex and twist: a stiff trailing edge with a dynamically responsive leading edge that absorbs lateral forces and produces a very vertical lift. This design reduces the wetted surface of the hull, improving comfort, control, and acceleration when planing. The M88 Superfast is built for durability under high loads while maintaining the stiffness needed for accurate tracking and explosive speed. Optimized for experienced sailors, it unlocks peak performance on boards in the 85–145 L range and mounts using a standard Tuttle box system.

Key Features:

• High-modulus carbon core for an ultra-thin, low-drag profile
• Active Flex design: rigid trailing edge with a responsive leading edge for controlled twist and vertical lift
• Ultra-thin section (8.8% thickness) to reduce hydrodynamic resistance and increase top speed
• Engineered for high stiffness under load to maintain precision and tracking at speed
• Reduced wetted surface effect for better comfort and hull efficiency at planing speeds
• Durable carbon construction optimized for repeated high-stress use
• Designed specifically for speed and slalom boards (85–145 L)
• Tuttle-box compatible for secure, direct mounting on compatible boards

Recommended Use:

Ideal for advanced and professional windsurfers seeking maximum speed and precise control on slalom and speed courses. Best suited to planing conditions and flat-to-choppy open-water environments where high top-end speed and reduced drag matter.
