Deep Tuttle Box Fin The Blade 40cm Select SML07330040

Deep Tuttle Box Fin The Blade 40cm Select SML07330040

Description:

The Blade is a race-focused deep-tuttle box fin engineered for maximum speed and efficiency on slalom and GPS-speed boards. Manufactured from high-modulus carbon, its ultra-thin, slender outline minimizes drag and delivers blistering acceleration and top-end velocity. The high-stiffness carbon layup ensures direct power transfer from board to fin for precise tracking and sustained drive while remaining lightweight for quick response. Designed specifically to pair with high-wind slalom and GPS-speed boards (recommended for boards up to 110 L), The Blade gives riders a razor-sharp feel that favors short stroke, high-cadence techniques. Durable carbon construction resists fatigue and maintains performance under repeated loading, making it suitable for competitive and advanced riders. For slalom use, Select recommends choosing a fin 1 cm larger than the standard fin selector to obtain more sustained power when necessary. The fin mounts to a standard Deep Tuttle box and integrates cleanly with race rig setups.
