Abstract
Masthead device for sailboats that indicates apparent wind direction composed of a rotating wind vane and a protractor arm encompassing multiple reference marks. These marks can be adjusted with greater compass accuracy to allow several settings in each quadrant creating a series of reference points enabling one to more accurately determine the apparent wind angle from a center point, and thus optimize sail trim, heading and boat speed.
