South Atlantic S 470 Self Steering Windvane

Designed for ocean-going yachts from 34 ft. to 60 ft.

Redefining the standard for large ocean-going yachts, the S 470 is an innovative servo-pendulum system designed for maximum efficiency. By perfectly balancing wind and hydrodynamic forces, it delivers rock-solid stability within a streamlined profile.

Utilizing advanced engineering concepts, we’ve achieved a disruptive weight of just 20 kilograms, allowing it to integrate seamlessly into modern, light stern structures while outperforming significantly heavier traditional systems.

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

"Simple, robust, and dependable: South Atlantic windvanes—making life on board easier with every mile."

S 470

The South Atlantic S 470 utilizes a sophisticated servo-pendulum system, harnessing the natural synergy between wind direction and water flow.
