On average, experienced wingfoilers can reach speeds between 15 to 25 knots (17 to 29 mph or 28 to 46 km/h) in ideal wind conditions. However, top-level riders have been known to achieve speeds exceeding 35 knots (40 mph or 65 km/h) during high-wind sessions or speed competitions. It’s important to note that these higher speeds are typically attained by advanced riders with specialized equipment and should not be attempted by beginners.

Several factors contribute to a wingfoiler’s speed:

1. Wind speed: Stronger winds generally enable faster speeds, as the wing generates more lift and propulsion.
2. Wing size: Larger wings provide more power and stability, allowing riders to maintain higher speeds in stronger winds. Conversely, smaller wings are more maneuverable and efficient in lighter winds.
3. Foil design: The shape, size, and material of the hydrofoil greatly influence a wingfoiler’s speed. High-aspect ratio foils with thin, streamlined profiles are designed for speed, while lower-aspect ratio foils offer more stability and lift at slower speeds.
4. Rider technique: Experienced wingfoilers can optimize their body position, wing control, and foil trim to maximize speed and efficiency.
