Power Box Fin M88 Superfast 33cm Select SML07510033

Power Box Fin M88 Superfast 33cm Select SML07510033

Description:

The Select M88 Superfast is a high-performance Power Box fin engineered for maximum speed and drive on slalom and speed windsurfing boards. Its structural core is made from high-modulus carbon composite, producing an ultra-thin hydrofoil profile (8.8% thickness) that minimizes drag in all points of sail. Select’s Active Flex concept combines a rigid trailing edge with a controlled, torsional-leading edge so the fin twists under load to produce a very vertical lift and dramatically reduce hull wetted surface. The result is exceptional top‑end speed, precise tracking and increased comfort at high velocity. Built for experienced sailors on planing boards, the M88 delivers sharp acceleration, powerful bite and reliable stability across aggressive conditions. The fin is designed to be used with Power Box mounting systems and is optimized for speed/slalom boards in the 85–145 L range.

Key Features:

• High-modulus carbon composite core for exceptional stiffness-to-weight ratio
• Ultra-thin 8.8% profile (8.8 mm at a 10 cm chord) to reduce drag and boost speed
• Active Flex design: rigid trailing edge with a flexible, torsionally active leading edge
• Produces vertical lift to lower hull wetted surface for higher top speeds and improved control
• Designed and tuned specifically for speed and slalom boards (85–145 L)
• Power Box compatible mounting for secure, direct connection to modern boards
• Precision manufacturing for consistent performance and durability under high loads
• Ideal for experienced and competitive sailors seeking maximum forward drive and stability
