Tuttle Box Fin M88 Supersport 40cm Select SML07521040

Tuttle Box Fin M88 Supersport 40cm Select SML07521040

Description:

The Select M88 Supersport SL is a high-performance freeride/freerace Tuttle-box fin engineered for riders who demand speed, control, and maneuverability. Constructed from high-modulus carbon with an ultra-thin 8.8% profile, the fin minimizes drag and delivers exceptional top-end velocity without sacrificing responsiveness. Its double-curved outline and precisely tuned Active Flex balance flex and twist to produce a very vertical lift, reducing hull wetted surface and improving directional stability at high speeds. The trailing edge is engineered for rigidity while the leading edge absorbs lateral forces, giving confident hold in gusty conditions and during aggressive turns. Designed primarily for freeride and freerace boards (85–150 L), the M88 Supersport is accessible enough for advanced amateurs yet tuned for competitive performance. Tuttle-box compatibility ensures a secure, low-profile mount for race and freeride setups.

Key Features:

• High-modulus carbon construction for maximum stiffness-to-weight ratio and longevity
• Ultra-thin 8.8% foil profile (8.8 mm per 10 cm chord) to minimize drag and increase speed
• Active Flex technology: rigid trailing edge with a dynamic, twist-capable leading edge for vertical lift and control
• Double-curved outline for exceptional maneuverability and smooth rail-to-rail transitions
• Optimized for freeride and freerace boards (85–150 L) — strong acceleration and high-speed stability
• Tuttle-box compatible for secure, race-ready mounting and low-drag integration with the hull
• Precision layup for consistent flex characteristics and repeatable performance in varied conditions
• Durable carbon finish resists delamination and maintains performance under repeated stress

Recommended Use:

Ideal for advanced recreational riders and competitive racers seeking a high-speed freeride/freerace fin with precise control. Best suited for freeride, freerace, and high-speed downwind or flatwater sessions on boards between 85 and 150 liters. Performs well in moderate to strong wind and chop where reduced hull wetted surface and vertical lift translate into higher sustained speeds. Pair with a Tuttle-box compatible freeride or race board and standard racing footstrap setups for best results.
