Advanced Notice of Arrival Law and Legal Definition

Any vessel entering United States waters from a foreign port is required to give a 96–hour Advanced Notice of Arrival (ANOA). Any vessel of 300 gross registered tonnage and greater is required to give the ANOA to the U.S. Coast Guard’s National Vessel Movement Center. Any vessel under 300 gross registered tons is required to give the ANOA to the appropriate Captain of the Port.
