Deep Tuttle Box Fin The Blade 31cm Select SML07330031

Deep Tuttle Box Fin The Blade 31cm Select SML07330031

Description:

The Blade is an ultra-thin, high-performance deep-tuttle fin engineered for maximum speed and precise tracking on slalom and GPS-speed boards. Manufactured from high-modulus carbon, its slender outline and stiff construction minimize drag and deliver instant power transfer for blistering acceleration and top-end velocity. The refined carbon layup keeps weight low while offering the durability and structural integrity needed for high-wind, competitive conditions. Designed specifically for use with high-wind slalom and GPS-speed boards (max. 110 liters), The Blade excels at maintaining drive and stability at high speeds. Riders will notice improved straight-line tracking, reduced cavitation, and efficient energy transfer on each stroke of the board. For slalom use, Select recommends choosing a fin 1 cm larger than the selector size to gain more sustained power when needed. The fin uses a deep-tuttle box mounting for secure, race-ready attachment to compatible boards.
