Tuttle Box Fin M88 Superfast 43cm Select SML07511043

Tuttle Box Fin M88 Superfast 43cm Select SML07511043

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 is manufactured from high‑modulus carbon, producing an ultra‑thin foil profile (8.8% thickness — e.g., 8.8 mm at a 10 cm chord) that minimizes drag in all points of sail. Select’s Active Flex design pairs a rigid trailing edge with a dynamically responsive leading edge, allowing the blade to twist under load and deliver very vertical lift for reduced wetted hull surface and exceptional high‑speed stability. The result is increased top‑end speed, precise tracking in planing conditions, and improved control when pushing the limits. Built for durability and repeated stress at race speeds, the M88 unlocks its full potential on speed and slalom boards in the 85–145 L range and fits standard tuttle box mounts.

Key Features: - High‑modulus carbon construction for maximum stiffness-to-weight ratio and durability
- Ultra‑thin 8.8% foil profile to minimize drag and improve top speed
- Active Flex technology: rigid trailing edge with a flexible, torque‑absorbing leading edge
- Generates vertical lift to reduce hull wetted surface and increase stability at speed
- Optimized for speed and slalom performance on 85–145 L boards
- Tuttle box compatible for secure, direct mounting to high‑performance boards
- Engineered for experienced sailors seeking precision, control, and maximum efficiency
- Low drag profile improves acceleration and sustained planing performance

Recommended Use: Ideal for advanced and professional windsurfers focused on speed and slalom disciplines. Best used on high‑performance planing boards (85–145 L) in medium to strong wind and flat to choppy planing conditions where reduced drag and high top‑end speeds are critical. Ensure your board has a tuttle box mount and pair with a race or slalom setup to fully benefit from the M88’s stiffness and Active Flex behavior.
