Question 224Navigation General

The correct answer is A) danger. A white buoy with an open-faced orange diamond on it indicates a special marker buoy that signifies a danger or obstruction to navigation. According to the U.S. Coast Guard's Aids to Navigation System, this type of buoy is used to mark hazards, wrecks, or other dangers that vessels should avoid. The open-faced orange diamond is a distinctive shape that makes this type of buoy easily identifiable. The other answer choices are incorrect because: B) a mooring buoy would have a different color scheme, C) operating restrictions are typically indicated by other types of regulatory buoys, and D) a danger buoy does not necessarily mean vessels are excluded from the area, but rather that caution is advised.
