Power Box Fin M88 Superfast 43cm Select SML07510043

Power Box Fin M88 Superfast 43cm Select SML07510043

Description: The M88 Superfast is Select’s most powerful, speed‑focused power box fin, engineered for experienced slalom and speed sailors. Its core is built from high‑modulus carbon to produce an ultra‑thin profile (8.8% thickness), minimizing drag through all points of sail and maximizing top‑end speed. Select’s Active Flex concept gives the fin a controlled balance of stiffness and twist — a rigid trailing edge with a compliant leading edge — to produce a vertical lift effect that reduces hull wetted surface and increases stability at high velocity. The precise flex and twist response improves control and comfort when pushing hard, while the carbon construction ensures excellent strength-to-weight performance and long-term durability. Optimized for speed and slalom boards in the 85–145 L range, the M88 Superfast unlocks its full performance only in the hands of skilled riders using a compatible power box setup.

Key Features: - High‑modulus carbon core for maximum stiffness and minimal weight. - Ultra‑thin profile: 8.8% thickness (example: 8.8 mm thickness at a 10 cm chord) to reduce hydrodynamic drag. - Active Flex design — rigid trailing edge with a flexible leading edge for dynamic twist and enhanced vertical lift. - Produces reduced wetted surface of the hull for higher top speeds and improved control. - Engineered specifically for speed and slalom applications (85–145 L boards). - Precision manufacturing for consistent performance and long service life. - Power box mounting for secure, low‑drag integration with modern boards. - Suited to advanced and professional sailors seeking maximum forward drive and stability at high speeds.

Recommended Use: Ideal for advanced and professional windsurfers focused on speed and slalom racing, the M88 Superfast excels on high‑performance boards and in conditions where top speed and responsiveness matter. Best used on speed or slalom boards between roughly 85 and 145 liters and mounted in a compatible power box. For best results pair with well‑tuned sails, race footstraps and a board set up for high‑speed planing; use a protective fin cover during transport and rinse with fresh water after saltwater use to preserve finish and performance.
