Regulated Navigation Area; Portsmouth Naval Shipyard, Kittery, ME and Portsmouth, NH

The Coast Guard is establishing a temporary regulated navigation area (RNA) on the Piscataqua River near the Portsmouth Naval Shipyard, Kittery, ME between Henderson Point Light on Seavey Island and the Memorial Bridge. This RNA establishes speed restrictions to eliminate vessel wake which could endanger the lives of divers and support crews working at the Portsmouth Naval Shipyard. The speed restrictions apply to all vessels transiting the regulated area unless authorized by the First Coast Guard District Commander or the Captain of the Port (COTP), Sector Northern New England.
