Do not approach within 100-yards, and slow to minimum speed within 500-yards of any large U.S. Naval vessel. The Coast Guard has established a Federal Regulation for a Naval Vessel Protection Zone, which became permanent on June 15, 2002. Under this regulation, all boats within 500 yards of any U. S. naval vessel over 100 feet in length must operate at the minimum speed necessary to maintain course.
However, now more than ever, it is important that all boaters understand the need to stay alert for any naval vessels that might be in the area, maintain a radio watch on VHF-FM Channel 16, and request verbal permission if you need to encroach upon a security zone.
