Downwind foils are specialized hydrofoils designed to harness the energy of ocean swells and wind-driven bumps for efficient, high-speed gliding over long distances. These foils typically feature long, slender front wings with high aspect ratios to maximize glide and efficiency, allowing riders to link bumps with minimal pumping or energy expenditure. They’re optimized for stability and low drag, helping riders maintain lift at lower speeds while covering more ground with each glide.
