Abstract
This invention sets forth a wind tracking device particularly useful on sailing vessels for determining the best sailing direction relative to the wind. The reference card is provided with color panels which cooperate with lines on the dome to indicate best direction. Further, the card has circular lines about the axis which cooperate with a dot on the axis of the dome to indicate a 360.degree. level condition around a horizontal plane.
