How is an East Cardinal Buoy topmarked?

Cardinal marks indicate where the safe water lies relative to the buoy, and the topmark helps you identify which direction it represents. For the East cardinal buoy, the topmark is two black cones with their apexes pointing away from each other. That distinctive double-cone shape tells you the safe water is to the east. Other topmarks would correspond to different marks, so they wouldn’t indicate east.
