Deep Tuttle Box Fin The Blade 41cm Select SML07330041

Deep Tuttle Box Fin The Blade 41cm Select SML07330041

Description:

The Blade is a high-performance Deep Tuttle box fin engineered for slalom and GPS-speed windsurf boards, delivering exceptional straight-line speed and control. Manufactured from high-modulus carbon, its ultra-thin profile and slender outline minimize drag and maximize acceleration for blistering top-end performance. The fin’s construction focuses on stiffness-to-weight efficiency, providing precise power transfer and efficient energy return with each stroke. Its shaping is optimized for high-wind slalom and GPS-speed boards up to 110 liters, giving riders stable tracking and sustained drive when pushing for speed. Durable carbon construction ensures long-term reliability while maintaining a lightweight feel that reduces rider fatigue. For slalom setups, sizing guidance recommends choosing the next 1 cm larger than standard selector sizes to achieve more sustained power when needed.

Key Features:

• High-modulus carbon construction for superior stiffness, low weight, and long-term durability
• Ultra-thin, slender outline designed to minimize drag and maximize top-end speed
• Optimized foil shape for efficient thrust and precise tracking on slalom/GPS boards
• Deep Tuttle box mount for secure, standard-compatible installation on performance boards
• Engineered for high-wind slalom and GPS-speed conditions (boards up to 110 L)
• Recommended slalom sizing: choose 1 cm larger than the fin selector for added sustained power
• Streamlined profile reduces cavitation and improves acceleration and straight-line stability
• Minimal flex characteristics for predictable handling at high speeds
