Description
Maximum speed with minimum effort
The Sonar High Aspect series is designed for maximum speed and efficiency, from kitefoil to prone foil surfing: you need very little pumping and power to glide, 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. With very good lift at high speed, the HA950 is one of North's core sizes for wingfoil and prone foil surfing.
Area 950 cm² · Span 1000 mm · Aspect ratio 10.6 · Pre-preg carbon
Who it's for
- Wingfoilers and kitefoilers looking for speed and efficiency.
- Prone foil surfers and downwind riders in ocean swell.
