§ 165.153 Regulated Navigation Area: Long Island Sound Marine Inspection and Captain of the Port Zone. ( a ) *Regulated Navigation Area location.* All waters of the Long Island Sound Marine Inspection and Captain of the Port (COTP) Zone, as delineated in 33 CFR 3.05-35, extending seaward 12 nautical miles from the territorial sea baseline, are established as a regulated navigation area (RNA).
( b ) *Applicability.* This section applies to all vessels operating within the RNA excluding public vessels.
( c ) *Definitions.* The following definitions apply to this section: *Commercial service* means any type of trade or business involving the transportation of goods or individuals, except service performed by a combatant vessel.
*Ferry* means a vessel that: ( 1 ) Operates in other than ocean or coastwise service;
( 2 ) Has provisions only for deck passengers or vehicles, or both;
( 3 ) Operates on a short run on a frequent schedule between two points over the most direct water route; and
( 4 ) Offers a public service of a type normally attributed to a bridge or tunnel.
*Public vessels* means vessels owned or bareboat chartered and operated by the United States, or by a State or political subdivision thereof, or by a foreign nation, except when such vessel is engaged in commercial service.
*Territorial sea baseline* means the line defining the shoreward extent of the territorial sea of the United States drawn according to the principles, as recognized by the United States, of the Convention on the Territorial Sea and the Contiguous Zone, 15 U.S.T. 1606, and the 1982 United Nations Convention on the Law of the Sea (UNCLOS), 21 I.L.M. 1261. Normally, the territorial sea baseline is the mean low water line along the coast of the United States.
( d ) *Regulations.* ( 1 ) Speed restrictions in the vicinity of Naval Submarine Base New London and Lower Thames River. Unless authorized by the Captain of the Port (COTP), vessels of 300 gross tons or more may not proceed at a speed in excess of eight knots in the Thames River from New London Harbor channel buoys 7 and 8 (Light List numbers 21875 and 21880 respectively) north through the upper limit of the Naval Submarine Base New London Restricted Area, as that area is specified in 33 CFR 334.75(a). The U.S. Navy and other Federal, State and municipal agencies may assist the U.S. Coast Guard in the enforcement of this rule.
( 2 ) *Enhanced communications.* Vessels of 300 gross tons or more and all vessels engaged in towing barges must issue securité calls on marine band or Very High Frequency (VHF) radio channel 16 upon approach to the following locations: ( i ) Inbound approach to Cerberus Shoal; and
( ii ) Outbound approach to Race Rock Light (USCG Light List No. 19815).
( 3 ) All vessels operating within the RNA that are bound for a port or place located in the United States or that must transit the internal waters of the United States, must be inspected to the satisfaction of the U. S. Coast Guard, before entering waters within three nautical miles from the territorial sea baseline. Vessels awaiting inspection will be required to anchor in the manner directed by the COTP. This section does not apply to vessels operating exclusively within the Long Island Sound Marine Inspection and COTP Zone, vessels on a single voyage which depart from and return to the same port or place within the RNA, all towing vessels engaged in coastwise trade, vessels in innocent passage not bound for a port or place subject to the jurisdiction of the United States, and all vessels not engaged in commercial service whose last port of call was in the United States. Vessels requiring inspection by the COTP may contact the COTP via marine band or Very High Frequency (VHF) channel 16, telephone at (203) 468-4401, facsimile at (203) 468-4418, or letter addressed to Captain of the Port, Long Island Sound, 120 Woodward Ave., New Haven, CT 06512.
( 4 ) All vessels operating within the RNA that are bound for a port or place located in the United States or that must transit the internal waters of the United States, must obtain authorization from the Captain of the Port (COTP) before entering waters within three nautical miles from the territorial sea baseline. Vessels awaiting COTP authorization to enter waters within three nautical miles from the territorial sea baseline will be required to anchor in the manner directed by the COTP. This section does not apply to vessels operating exclusively within the Long Island Sound Marine Inspection and COTP Zone, vessels on a single voyage which depart from and return to the same port or place within the RNA, all towing vessels engaged in coastwise trade, vessels in innocent passage not bound for a port or place subject to the jurisdiction of the United States, and all vessels not engaged in commercial service whose last port of call was in the United States. Vessels may request authorization from the COTP by contacting the COTP via marine band or Very High Frequency (VHF) channel 16, telephone at (203) 468-4401, facsimile at (203) 468-4418, or letter addressed to Captain of the Port, Long Island Sound, 120 Woodward Ave., New Haven, CT 06512.
( 5 ) Vessels over 1,600 gross tons operating in the RNA within three nautical miles from the territorial sea baseline that are bound for a port or place located in the United States or that must transit the internal waters of the United States must receive authorization from the COTP prior to transiting or any intentional vessel movements, including, but not limited to, shifting berths, departing anchorage, or getting underway from a mooring. This section does not apply to vessels in innocent passage not bound for a port or place subject to the jurisdiction of the United States.
( 6 ) *Ferry vessels.* Vessels of 300 gross tons or more are prohibited from entering all waters within a 1200-yard radius of any ferry vessel transiting in any portion of the Long Island Sound Marine Inspection and COTP Zone without first obtaining the express prior authorization of the ferry vessel operator, master, COTP, or the designated COTP on-scene patrol.
( 7 ) *Vessels engaged in commercial service.* No vessel may enter within a 100-yard radius of any vessel engaged in commercial service while that vessel is transiting, moored, or berthed in any portion of the Long Island Sound Marine Inspection and COTP zone, without the express prior authorization of the vessel's operator, master, COTP, or the designated COTP on-scene representative.
