The United States Coast Guard maintains roughly 145 Aids to Navigation Boats(ANB). These boats were designed primarily to serve within the inland waters of the United States. However, the 55' ANB is often employed to service offshore aids as well.

The 55' ANB has a crane that is used for hoisting and securing the various buoys and aids to navigation that the Coast Guard supplies for waterways. The boat is 55 feet long to the transom, and 58 feet 9 inches to the end of the swim platform. It is 25 feet tall unfixed and has a navigational draft of 8 feet. The 55' ANB goes approximately 25 knots when at full speed.

Most Aids to Navigation Boats of the United States Coast Guard are stationed at Aids to Navigation Teams (ANT). These are teams of Boatswain's mates and Machinery Technician's and non-rated personnel that service small buoys, jetty lights and light houses.
