a. Article III of the Convention on the International Regulations for Preventing Collisons at Sea, 1972 (72 COLREGS), done at London, October 20, 1972, as rectified by Proces-Verbal of December 1, 1973, provides that a party may notify the Secretary-General of the International Maritime Organization (IMO, formerly Inter-Governmental Maritime Consultative Organization or IMCO) that it extends the application of the Convention to territory for which it is responsible for international relations. Since it is the intention of the United States that the 72 COLREGS apply to all U.S. territories and possessions to the same extent that the International Regulations for Preventing Collisions at Sea, 1960 (60 COLREGS) (16 USC 794, TIAS 5813) previously applied, the United States has given notice to the Secretary-General that the provisions of the 1972 COLREGS are applicable on July 15, 1977, to the following territories and possessions for which the United States is responsible for international relations:
b. In accordance with Article III, other parties to the Convention have notified the Secretary-General that application of 72 COLREGS is extended. These parties with their territorial extensions are listed in Table 1.
Because earlier formulations of the COLREGS were not elaborated as treaties, they came into force by the almost simultaneous enactment of domestic legislation by the majority of maritime nations. The COLREGS were judicially considered as being customary international law, that is to say international law based upon the consensus of maritime nations rather than upon an express instrument. Because 72 COLREGS was elaborated as a treaty, and under usual treaty practice only parties are bound, there may be a period of time after the 72 COLREGS come into force during which the ships of a nation not party to 72 COLREGS might not be considered as being bound to comply with the convention. While it is most likely that the 72 COLREGS will rapidly achieve the status of customary international law, thereby obviating any concern on the part of the mariner as to whether a particular nation is a party, it does not necessarily follow that the courts in all nations will apply 72 COLREGS to the vessels of a non-party nation. In the absence of changes in their domestic law there may be certain nations that will feel compelled to continue 60 COLREGS in force, despite the coming into force of 72 COLREGS.
The following nations are Contracting Parties for which 72 COLREGS will apply upon the Convention's entry into force:
The following nations have accepted the 60 COLREGS but are not Contracting Parties to 72 COLREGS:

CGD 76-130, 42 FR 17111, Mar. 31, 1977, unless otherwise noted. Redesignated by CGD 81-017, 46 FR 28154, May 26, 1981.
As used in this part:
Vessels of special construction or purpose which cannot fully comply with the light, shape, and sound signal provisions of 72 COLREGS without interfering with their special function may instead meet alternative requirements. The Chief of the Marine Safety Division in each Coast Guard District Office makes this determination and requires that alternative compliance be as close as possible with the 72 COLREGS. These regulations set out the procedure by which a vessel may be certified for alternative compliance. The information collection and recordkeeping requirements in §§ 81.5 and 81.18 have been approved by the Office of Management and Budget under OMB control No. 2115-0073.
(a) The owner, builder, operator, or agent of a vessel of special construction or purpose who believes the vessel cannot fully comply with the 72 COLREGS light, shape, or sound signal provisions without interference with its special function may apply for a determination that alternative compliance is justified. The application must be in writing, submitted to the Chief of the Marine Safety Division of the Coast Guard District in which the vessel is being built or operated, and include the following information:
(1) The name, address, and telephone number of the applicant.
(2) The identification of the vessel by its:
(i) Official number;
(ii) Shipyard hull number;
(iii) Hull identification number; or
(iv) State number, if the vessel does not have an official number or hull identification number.
(3) Vessel name and home port, if known.
(4) A description of the vessel's area of operation.
(5) A description of the provision for which the Certificate of Alternative Compliance is sought, including:
(i) The 72 COLREGS Rule or Annex section number for which the Certificate of Alternative Compliance is sought;
(ii) A description of the special function of the vessel that would be interfered with by full compliance with the provision of that Rule or Annex section; and
(iii) A statement of how full compliance would interfere with the special function of the vessel.
(6) A description of the alternative installation that is in closest possible compliance with the applicable 72 COLREGS Rule or Annex section.
(7) A copy of the vessel's plans or an accurate scale drawing that clearly shows:
(i) The required installation of the equipment under the 72 COLREGS,
(ii) The proposed installation of the equipment for which certification is being sought, and
(iii) Any obstructions that may interfere with the equipment when installed in:
(A) The required location; and
(B) The proposed location.
(b) The Coast Guard may request from the applicant additional information concerning the application.
The Chief of the Marine Safety Division issues the Certificate of Alternative Compliance to the vessel based on a determination that it cannot comply fully with 72 COLREGS light, shape, and sound signal provisions without interference with its special function. This Certificate includes—
(a) Identification of the vessel as supplied in the application under § 81.5(a)(2);
(b) The provision of the 72 COLREGS for which the Certificate authorizes alternative compliance;
(c) A certification that the vessel is unable to comply fully with the 72 COLREGS lights, shape, and sound signal requirements without interference with its special function;
(d) A statement of why full compliance would interfere with the special function of the vessel;
(e) The required alternative installation;
(f) A statement that the required alternative installation is in the closest possible compliance with the 72 COLREGS without interfering with the special function of the vessel;
(g) The date of issuance;
(h) A statement that the Certificate of Alternative Compliance terminates when the vessel ceases to be usually engaged in the operation for which the certificate is issued.
The Certificate of Alternative Compliance terminates if the information supplied under § 81.5(a) or the Certificate issued under § 81.9 is no longer applicable to the vessel.
(a) In accordance with 33 U.S.C. 1605(c), a notice is published in the
(1) Each Certificate of Alternative Compliance issued under § 81.9; and
(2) Each Coast Guard vessel determined by the Commandant to be a vessel of special construction or purpose.
(b) Copies of Certificate of Alternative Compliance and documentation concerning Coast Guard vessels are available for inspection at Marine Safety, Security and Environmental Protection, U.S. Coast Guard Headquarters, 2100 Second Street SW., Washington, DC 20593-0001.
(c) The owner or operator of a vessel issued a Certificate shall ensure that the vessel does not operate unless the Certificate of Alternative Compliance or a certified copy of that Certificate is on board the vessel and available for inspection by Coast Guard personnel.
Each vessel under the 72 COLREGS, except the vessels of the Navy, is exempt from the requirements of the 72 COLREGS to the limitation for the period of time stated in Rule 38 (a), (b), (c), (d), (e), (f), and (g) if:
(a) Her keel is laid or is at a corresponding stage of construction before July 15, 1977; and
(b) She meets the International Regulations for Preventing Collisions at
14 U.S.C. 2, 633; 33 U.S.C. 1602; E.O. 11964, 42 FR 4327, 3 CFR, 1977 Comp., p. 88; 49 CFR 1.46(n).
This part contains the interpretative rules concerning the 72 COLREGS that are adopted by the Coast Guard for the guidance of the public.
Rule 24(b) of the 72 COLREGS states that when a pushing vessel and a vessel being pushed ahead are rigidly connected in a composite unit, they are regarded as a power-driven vessel and must exhibit the lights under Rule 23. A “composite unit” is interpreted to be a pushing vessel that is rigidly connected by mechanical means to a vessel being pushed so they react to sea and swell as one vessel. “Mechanical means” does not include the following:
(a) Lines.
(b) Hawsers.
(c) Wires.
(d) Chains.
For the purposes of Rule 30 of the 72 COLREGS, a
An unmanned barge being towed may use the exception of COLREGS Rule 24(h). However, this exception only applies to the vertical sector requirements.
