Tuttle Box Fin The Blade 37cm Select SML07320037

Tuttle Box Fin The Blade 37cm Select SML07320037

Description:

The Blade is an ultra-thin tuttle-box fin engineered for maximum straight-line speed and minimal drag. Manufactured using high-modulus carbon, its slender outline and tuned stiffness deliver blistering acceleration and sustained top-end performance. The advanced carbon construction provides excellent stiffness-to-weight ratio for immediate power transfer and long-term durability. The Blade is specifically shaped for use with high-wind slalom and GPS-speed windsurfing boards (recommended up to 110 liters), offering precise tracking and reduced cavitation at high speeds. Its low-drag profile improves efficiency so riders can maintain higher speeds with less effort. For slalom applications, sizing guidance calls for selecting a fin 1 cm larger than standard fin-selector recommendations when extra sustained power is needed.

Key Features:

• High-modulus carbon construction for outstanding stiffness-to-weight ratio
• Ultra-thin, slender blade profile to minimize drag and maximize top speed
• Tuned outline for fast, stable tracking at high speeds
• Designed for tuttle-box mounting systems (Tuttle Box fin)
• Optimized for high-wind slalom and GPS-speed boards (max. 110 L)
• Durable carbon layup for long service life in demanding conditions
• Sizing tip included: choose +1 cm for slalom to increase sustained power
• Ideal balance of responsiveness and straight-line stability for performance riders
