Description
Maximum speed with minimum effort
The Sonar High Aspect series is built for maximum speed and efficiency, from kitefoiling to prone foil surfing: you need very little pumping and power to get up and flying, 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 HA1150 is one of the core sizes for wingfoiling and prone foil surfing, and is designed for light or experienced riders who want to fly on fast ocean swell.
Area 1150 cm² · Span 1100 mm · Aspect ratio 10.5 · Pre-preg carbon
Who it's for
- Wingfoilers and kitefoilers looking for speed and efficiency.
- Prone foil surfers and downwinders on ocean swell.
