Power Box Fin The Blade 40cm Select SML07310040

Power Box Fin The Blade 40cm Select SML07310040

Description:

The Blade is an ultra-thin, high-performance power fin engineered for maximum speed and efficient tracking on slalom and GPS-speed windsurfing boards. Manufactured from high-modulus carbon, its slender outline and minimal cross-section reduce drag and deliver blistering acceleration and top-end speed. The blade’s stiffness and refined profile transfer power cleanly to the board, producing sustained drive with minimal energy loss. Designed specifically to pair with high-wind slalom and GPS-speed boards (recommended for boards up to 110 L), The Blade gives riders precise control at high speeds and improved straight-line stability. Its construction emphasizes durability and fatigue resistance while keeping weight low for quick responsiveness. For slalom use, choose a fin 1 cm larger than your selector recommendation to obtain more sustained power when needed. The Blade fits standard Power Box mounts for straightforward installation and interchangeability.
