U.S. Aids to Navigation System
The U.S. Aids to Navigation System is a system maintained by the U.S. Coast Guard, consisting of visual, audible, and electronic signals which are designed to assist the prudent mariner in the process of navigation. The aids to navigation system is not intended to identify every shoal or obstruction to navigation which exists in the navigable waters of the United States, but rather provides for reasonable marking of marine features as resources permit.
