Tuttle Box Fin M88 Superfast 29cm Select SML07511029

Tuttle Box Fin M88 Superfast 29cm Select SML07511029

Description:

The Select M88 Superfast is a high-performance Tuttle-box fin engineered for speed and slalom windsurfing boards. Built around a high-modulus carbon core, the fin delivers an ultra-thin profile (8.8% thickness) that dramatically reduces drag and keeps the foil efficient at all angles. Select’s Active Flex concept pairs a stiff trailing edge with a dynamically twisting leading edge, producing a vertical lift effect that reduces hull wetted surface and improves stability at top speeds. This finely tuned balance of flex and torsion gives exceptional control and comfort in demanding conditions while maintaining durability under high loads. Optimized for boards between 85 and 145 liters, the M88 Superfast is intended for experienced sailors who want maximum acceleration and straight-line performance. The fin installs into a Tuttle-box system and unlocks its full potential when combined with a speed or slalom setup.

Key Features:

• High-modulus carbon core for excellent stiffness-to-weight ratio and long-term durability
• Ultra-thin foil section (8.8% thickness) to minimize drag and maximize top-end speed
• Active Flex design: rigid trailing edge with a leading edge engineered to absorb lateral forces and twist
• Vertical lift generation reduces hull wetted surface for improved stability and reduced drag
