Deep Tuttle Box Fin The Blade 33cm Select SML07330033

Deep Tuttle Box Fin The Blade 33cm Select SML07330033

Description:

The Blade is an ultra-thin, high-performance deep-tuttle fin engineered for speed-focused windsurfing boards. Manufactured from high-modulus carbon, its slender outline minimises drag and delivers blistering acceleration with exceptional stiffness and responsiveness. The fin’s construction provides precise tracking and efficient energy transfer, making it ideal for slalom and GPS-speed disciplines. Designed to pair with high-wind slalom and GPS-speed boards (max. 110 liters), The Blade gives riders a direct, race-ready feel while maintaining durability under high loads. Its minimalist profile reduces cavitation and keeps water flow clean for sustained top-end velocity. For slalom setups, riders are advised to choose a fin 1 cm larger than standard selector recommendations to gain more sustained power when required.

Key Features:

• High-modulus carbon construction for maximum stiffness-to-weight ratio and responsiveness
• Ultra-thin, hydrodynamic blade profile to minimise drag and improve top speed
• Deep-tuttle box fit for secure mounting to compatible boards
• Optimised outline for slalom and GPS-speed boards (recommended up to 110 L)
• Direct power transfer and precise tracking for competitive performance
• Durable carbon layup designed to withstand high loads and repeated use
• Low-cavitation design for smoother water flow and reduced turbulence
• Sizing note: choose +1 cm for slalom to increase sustained power when needed

Recommended Use:

This fin is best suited for advanced and professional windsurfers pursuing slalom or GPS-speed performance on high-wind days. It performs optimally on high-wind slalom and speed-oriented boards up to about 110 liters and in conditions where low drag and high top-end speed are priorities. Use with boards fitted for a deep-tuttle box; consider pairing with a race-oriented mast/boom setup and proper footstraps for maximum control. For slalom racing or high-power runs, select a fin 1 cm larger than your usual choice to achieve more sustained drive.
