Power Box Fin The Blade 39cm Select SML07310039

Power Box Fin The Blade 39cm Select SML07310039

Description:

The Blade is a high-performance power box fin engineered for speed-oriented windsurfing disciplines. Manufactured using high modulus carbon, the ultra-thin blade delivers exceptional stiffness and a slender outline that minimizes drag for blistering top-end speeds. Its construction is optimized to convert board drive into forward momentum with precise tracking and low resistance, making it ideal for slalom and GPS-speed setups. The fin’s shape and layup provide sustained power and efficient acceleration while remaining durable under heavy use. Designed specifically to pair with high-wind slalom and GPS-speed boards (up to 110 liters), The Blade gives experienced sailors a pronounced performance advantage in race and speed runs. For slalom use, consider selecting a fin 1 cm larger than the fin selector recommendation to gain more sustained power when needed.

Key Features:

• High modulus carbon construction for maximum stiffness-to-weight ratio
• Ultra-thin, slender blade profile minimizes drag for higher top speeds
• Engineered for powerbox mounting systems (Power Box compatible)
• Optimal shape for high-wind slalom and GPS-speed boards (max. 110 L)
• Delivers precise tracking and efficient forward drive under load
• Durable carbon layup designed for repeated high-stress use
• Sizing recommendation: choose +1 cm for extra sustained power in slalom
• Low cavitation characteristics for smoother water flow at speed
