Power Box Fin The Blade 38cm Select SML07310038

Power Box Fin The Blade 38cm Select SML07310038

Description:

The Blade is an ultra-thin, high-performance power box fin engineered for slalom and GPS-speed windsurfing. Manufactured from high-modulus carbon, the fin combines an extremely slender outline with a stiff carbon layup to minimize drag and deliver blistering top-end speed. Its streamlined shape produces efficient thrust and rapid acceleration while keeping drag and vibration to a minimum, translating rider input into direct forward drive. The construction emphasizes durability and torsional stiffness so the fin maintains performance under high loads and repeated use. Specifically shaped to pair with high-wind slalom and GPS-speed boards (up to 110 liters), The Blade gives experienced riders the precision and speed needed for competitive conditions. For slalom use, riders are recommended to select a fin 1 cm larger than indicated by standard fin selectors to achieve more sustained power when required. The fin fits standard Power Box installations for straightforward mounting on compatible boards.

Key Features:

• High-modulus carbon construction for maximum stiffness-to-weight ratio and long-term durability
• Ultra-thin, slender blade profile to minimize drag and increase top-end speed
• Precision shaping optimized for slalom and GPS-speed boards (max. 110 L)
• Efficient thrust delivery for improved acceleration and sustained velocity
• Low vibration design for a smoother, more controlled ride at high speeds
• Power Box compatible for secure, tool-free installation in standard fin boxes
• Recommended upsizing (+1 cm) for slalom applications to gain sustained power
• Lightweight design that reduces swing weight and improves handling responsiveness
