Description
Maximum speed with minimum effort
The Sonar High Aspect series is designed for maximum speed and efficiency, from kitefoiling to prone foil surfing: you need very little pumping and power to get up on the foil, its thin profile reduces drag and the tips don’t ventilate when they come out of the water, so you can turn tighter at high speed without losing speed. The HA650 has less area and a higher stall speed: maximum efficiency and lift for high-speed wingfoiling, racing and kitefoiling.
Area 650 cm² · Span 810 mm · Aspect ratio 10.1 · Pre-preg carbon
Who it's for
- Wingfoilers and kitefoilers looking for speed and efficiency.
- Prone foil surfers and downwinders on ocean swell.
What makes it special
01 Efficiency for advanced kite and wing
Incredibly efficient for advanced-level kitefoiling and wingfoiling.
02 Ventilation-free tips
The tips don’t ventilate when they leave the water, so you can turn tight at higher speed.
Where it shines: freeride wing (advanced riders); wave wing (advanced riders); high-speed wing (advanced riders); wing downwind (advanced riders); tow surfing (big waves) (advanced riders); prone surfing in big waves (advanced riders); kitefoil.
