Power Box Fin The Blade 37cm Select SML07310037

Power Box Fin The Blade 37cm Select SML07310037

Description:

The Blade is an ultra-thin, high-performance power box fin engineered for slalom and GPS-speed windsurfing. Manufactured using high modulus carbon, its slender outline and refined foil minimize drag and deliver blistering straight-line speeds with precise tracking. The stiff carbon construction provides immediate response and excellent energy transfer from rider to board, improving acceleration and top-end performance. Its low-drag profile also helps maintain stability at high speeds and reduces ventilation in choppy conditions. The Blade is specifically shaped to work with high-wind slalom and GPS-speed boards up to 110 liters, offering an optimal balance of drive and control for advanced riders. For slalom setups, Select recommends choosing a fin 1 cm larger than the fin selector suggests to obtain more sustained power when needed.

Key Features:

• High modulus carbon construction for superior stiffness, responsiveness and durability
• Ultra-thin blade profile designed to minimize drag and maximize top speed
• Optimized foil for precise tracking and efficient energy transfer
• Engineered specifically for high-wind slalom and GPS-speed boards (max. 110 L)
• Power Box mounting format for secure, low-profile integration with compatible boards
