Power Box Anti-Weed Lessacher Weed Blade Fin G10 40cm Unifiber UF037029400

Description:

The Power Box Anti-Weed Lessacher Weed Blade is a purpose-built, high-performance surf/foil fin engineered to cut through weed-choked spots and deliver exceptional speed and lift. Constructed from stiff G10 fiberglass-epoxy laminate with an asymmetrical profile, the blade offers a powerful, direct feel and excellent durability in demanding conditions. This latest Lessacher design moves the leading edge slightly forward compared to the former FWD model, improving overall performance and top-end speed while maintaining familiar, predictable fin behavior. The anti-weed geometry reduces clogging and maintains consistent thrust in vegetation-heavy water, giving a smoother ride and fewer interruptions. Designed for Power Box mounting systems, the fin works well with standard foil and board setups; for best results choose a fin 8–10 cm shorter than you would normally use. Rugged construction and refined hydrodynamics make it ideal for riders seeking speed, reliability and weed-resistant performance.

Key Features:

• Stiff G10 fiberglass-epoxy laminate construction for strength and longevity
• Asymmetrical profile tuned for lift and efficient forward drive
• Anti-weed blade geometry minimizes vegetation clogging and preserves thrust
• Leading edge positioned slightly forward for improved top-end performance vs. predecessor
