South Atlantic S 301 Self Steering Windvane

Designed for small ocean-going yachts from 18 ft. to 30 ft.

Redefining the standard for small yachts, the S 301 is an innovative system designed for maximum efficiency. By perfectly balancing wind and hydrodynamic forces, it delivers rock-solid stability for bluewater sailing within a streamlined profile.

Utilizing advanced engineering concepts, we’ve achieved a disruptive weight of just 12 kilograms. This allows it to integrate seamlessly into modern, light stern structures while outperforming significantly heavier traditional units. It is the ultimate solution for ocean passages.

"The silent crew member that never sleeps and never tires."
