Tuttle Box Fin The Blade 39cm Select SML07320039

Tuttle Box Fin The Blade 39cm Select SML07320039

Description:

The Blade is an ultra-thin, high-performance tuttle-box fin engineered for blistering straight-line speed and precise control. Manufactured from high modulus carbon, the Blade delivers a very high stiffness-to-weight ratio and a slender outline that minimizes drag for maximum top-end velocity. Its construction and profile have been optimized for pairing with high-wind slalom and GPS-speed boards (recommended for boards up to 110 liters), giving riders immediate response and sustained power. The thin, streamlined shape reduces turbulence and improves tracking, while the material choice ensures durability and fatigue resistance under repeated loading. For slalom use, riders are advised to select a fin 1 cm larger than the standard fin selector to obtain more sustained drive when needed. The Blade mounts in a standard tuttle box and is suited to riders who demand speed, precision and lightweight performance.

Key Features:

• High modulus carbon construction for exceptional stiffness and low weight
• Ultra-thin, slender blade profile to minimize drag and turbulence
• Optimized for high-wind slalom and GPS speed boards (max. 110 L)
• Fast response and precise tracking for high-speed runs
• Durable carbon layup resists repeated loading and maintains shape
• Tuttle box compatible for secure, easy mounting
• Size guidance: choose +1 cm for more sustained power in slalom setups

Recommended Use:

Ideal for advanced and professional windsurfers and speed specialists seeking maximum straight-line speed and tracking stability. Best suited to slalom and GPS speed runs on high-wind days and boards designed for speed (recommended board volume up to 110 liters). Performs strongest in open-water, high-wind or flat-to-choppy conditions where reduced drag and high stiffness translate directly into higher speeds. Use with a tuttle-box equipped board; consider pairing with appropriately sized footstraps and a rigid, speed-oriented setup.
