Question 335Navigation General

The correct answer is C) Yellow buoy lettered "N". The yellow buoy lettered "N" is used to mark an anchorage area. According to the U.S. Coast Guard's Aids to Navigation System, yellow buoys are used to mark special areas, such as anchorages, which vessels should approach with caution. The letter "N" on the buoy further identifies it as marking an anchorage. The other options are incorrect because they do not represent buoys used to mark anchorages. A white buoy with a green top, a white buoy numbered "3", and a white buoy with orange bands have different purposes within the Aids to Navigation System.
