Abstract: This invention relates to a wind direction indicator spherically rotatable about a liquid supported poly axial magnetic compass. The wind direction indicator determines the wind direction without any pivotal support. The wind direction structure is orientated to the reference center of the compass by means of the transparency of the spherically rotating structure. The displacement of the wind direction indicator base upon the wind responsive rudder and wing structure thereon causes the device to give an accurate direction of the wind that may be used during sailboat racing. The spherically rotatable structure or wind direction indicator is independently movable regardless of the mounting of the device on the sailboat or any other support structure. The frictional contact between the boat support structure and the device is minimized because there is no surface to surface contact between the moving elements.
