OpenWind is an instrument designed to provide sailors with precised measurements of the wind direction and speed. The application uses an advanced algorithm to calculate the true wind speed and direction in any environmental condition (e.g.: boat drift, current).
The usual half sphered anemometer cups measures differently depending on the angle of heel. The design of the blades from the OpenWind anemometer can measure more precisely with angle variation. The innovative wind cup design is used under license from SailTimer Inc.
