Aids to Navigation – Mapping the Waters

Buoy tenders

One important mission entrusted to the Coast Guard is the care and maintenance of maritime aids to navigation. Much like drivers need stoplights, street signs, and universally accepted driving rules, boaters also need equivalent nautical 'rules of the road.'

The Coast Guard is responsible for ensuring this network of signs, symbols, buoys, markers, lighthouses, and regulations is up to date and functioning properly so recreational and commercial boaters can safely navigate the maritime environment.
