Power Box Fin The Blade 31cm Select SML07310031

Power Box Fin The Blade 31cm Select SML07310031

Description:

The Blade is an ultra-thin, high-performance power box fin engineered for maximum speed and efficiency on slalom and GPS-speed boards. Manufactured from high modulus carbon, its slender outline and advanced carbon layup minimize drag while delivering exceptional stiffness and instant power transfer. The fin’s thin profile and precision foil reduce turbulence to produce blistering straight-line speeds and highly predictable tracking at high pace. Built to pair with high-wind slalom and GPS-speed boards (recommended up to 110 liters), The Blade gives riders a competitive edge in flat-to-choppy open-water speed conditions. Durable carbon construction ensures long-term structural integrity while keeping weight low for rapid acceleration and reduced fatigue. For slalom setups, select a fin 1 cm larger than the standard fin selector to gain more sustained power when needed. Designed for Power Box fitting systems, it integrates cleanly with modern speed-board hardware.

Key Features:

• Constructed from high modulus carbon for an excellent strength-to-weight ratio and high stiffness
• Ultra-thin, slender outline that minimizes drag and turbulence for top-end speed
• Precision foil profile for predictable tracking and efficient water flow
• Optimized for high-wind slalom and GPS-speed boards (max. 110 L)
