Question 342Navigation General

The correct answer is D) Lettering on the buoy. Buoys marking special areas such as spoil grounds, anchorage areas, cable areas, and military exercise areas are identified by yellow coloration. The specific area is indicated by lettering on the buoy, not by the shape of the topmark. Other types of special marks may use topmarks of different shapes, but for these yellow special areas, the key identifying feature is the lettering that identifies the specific area or purpose. The other answer choices (A, B, C) describe different topmark shapes, but these are not the distinguishing characteristic for these yellow special area buoys. The lettering on the buoy is the correct way to determine the specific area you are in.
