Power Box Fin M88 Superfast 37cm Select SML07510037

Power Box Fin M88 Superfast 37cm Select SML07510037

Description:

The M88 Superfast is Select Hydrofoils’ most powerful and fastest power‑box fin to date, built specifically for speed and slalom performance. Its core structure is manufactured from high‑modulus carbon, producing an ultra‑thin foil profile (8.8% thickness — 8.8 mm for a 10 cm chord) that dramatically reduces drag through all points of sail. Select’s Active Flex design precisely balances flex and twist: a rigid trailing edge with a dynamically responsive leading edge absorbs lateral forces and generates a very vertical lift. The result is reduced wetted hull surface, increased stability and exceptional control at high speeds. Designed for experienced sailors, the M88 delivers top‑end acceleration and sustained speed on speed and slalom boards. It installs in a standard Power Box and is optimized for boards in the 85–145 L range.

Key Features:

• High‑modulus carbon construction for light weight, stiffness and durability
• Ultra‑thin foil profile (8.8% thickness) to minimize hydrodynamic drag
• Active Flex technology: rigid trailing edge with a compliant leading edge for controlled twist and lift
• Produces a vertical lift effect that reduces hull wetted area for higher top speed and better stability
• Engineered specifically for speed and slalom sailing on 85–145 L boards
• Power Box compatibility for secure, low‑profile installation
• Optimized for experienced sailors seeking maximum performance and precision control
• Durable layup and production techniques to maintain consistent performance at high loads

Use with Power Box‑equipped boards and ensure proper fin installation and board setup; pairing with performance rigs, streamlined footstraps and tuned foil/board trim will unlock the fin’s potential.
