Deep Tuttle Box Fin M88 Superfast 45cm Select SML07512045

Deep Tuttle Box Fin M88 Superfast 45cm Select SML07512045

Description:

The M88 Superfast is Select’s most powerful, speed-focused deep-tuttle fin, engineered specifically for high-performance foiling on speed and slalom boards. Its core is constructed from high-modulus carbon, yielding an ultra-thin profile (8.8% thickness, e.g., 8.8 mm at a 10 cm chord) to minimize drag and maximize top-end speed. Select’s Active Flex concept combines a rigid trailing edge with a compliant leading edge that twists and absorbs lateral forces, creating a very vertical lift that reduces hull wetted surface. This precise balance of stiffness and twist delivers exceptional control and stability at high speeds while preserving efficiency and responsiveness. The fin is optimized for use with 85–145 L speed and slalom boards and is best exploited by experienced sailors seeking maximum acceleration and reduced drag. Durable carbon construction and refined production methods ensure consistent performance session after session. Compatible with deep-tuttle box mounts, the M88 is a plug-and-play upgrade for racers and speed-focused foilers.
