Deep Tuttle Box Fin The Blade 39cm Select SML07330039

Deep Tuttle Box Fin The Blade 39cm Select SML07330039

Description:

The Blade is an ultra-thin, high-performance deep-tuttle fin engineered for maximum speed and minimal drag. Manufactured from high-modulus carbon, its slender outline and stiff construction deliver instant power transfer and blistering top-end speed on slalom and GPS speed boards. The fine-profile blade reduces turbulence and drag while maintaining tracking and stability at high speeds. Designed specifically for pairing with high-wind slalom and GPS-speed boards (recommended up to 110 liters), The Blade is optimized for sprint runs and race conditions. Its construction offers excellent durability and fatigue-resistant stiffness race after race. For slalom use, riders should select a fin 1 cm larger than conventional fin-selector recommendations to gain more sustained power when needed. The deep-tuttle base ensures a secure, predictable connection to compatible board boxes.

Key Features:

• High-modulus carbon construction for maximum stiffness and light weight
• Ultra-thin, slender blade profile for minimal drag and top-speed performance
• Deep Tuttle box base for secure, race-ready mounting on compatible boards
