Tuttle Box Fin M88 Superfast 42cm Select SML07511042

Tuttle Box Fin M88 Superfast 42cm Select SML07511042

Description:

The M88 Superfast is Select’s most powerful and fastest Tuttle-box fin, purpose-built for high-speed and slalom windsurfing. Its core structure uses high-modulus carbon composite formed into an ultra-thin profile (8.8% thickness — 8.8 mm for a 10 cm chord) to minimize drag and maximize top-end speed. Select’s Active Flex concept delivers a precise balance of flex and twist: a stiff trailing edge paired with a dynamic leading edge that absorbs lateral loads and creates a very vertical lift. This vertical lift reduces hull wetted surface, improving stability, control and comfort at high speeds. The fin is optimized for use on speed and slalom boards between 85 and 145 liters, and it performs best in the hands of experienced sailors seeking maximum efficiency and race-level performance. Finished in a natural carbon look, the M88 is built for durability under repeated high-load conditions and integrates directly with Tuttle-box mounts.

Key Features:

• High-modulus carbon composite core for extreme stiffness-to-weight ratio and minimal drag
• Ultra-thin profile (8.8% thickness) for outstanding speed and reduced hydrodynamic resistance
• Active Flex design: rigid trailing edge with a torsion-responsive leading edge for controlled twist and vertical lift
• Engineered to reduce hull wetted area, improving top-end speed and stability
• Optimized geometry for speed and slalom performance on 85–145 L boards
• Tuttle-box compatible for secure, race-ready mounting
