District Commanders commanders of mainte nance and logistics commands and unit commanding officer shall ensure implementation and compliance with this manual3 DIRECTIVES AFFECTED COMDTINST M166722B is cancelled4 DISCUSSION a This manual contains the International Regulations for Prevention of Collisions at Sea 1972 72 COLREGS It also contains the Inland Navigation Rules which were enacted by law on 24 December 1980 and became effective for all Inland waters except the Great Lakes on 24 December 1981 The Inland Rules became effective on the Great Lakes on 1 March 1983 Some differences do remain between the International and Inland Rules The sidebyside pre sentation of the Rules in this publication will allow mariners to deter mine those differences b On 19 November 1989 nine amendments to the 72 COLREGS became effective These nine amendments are technical in nature and are incorporated in this publication The Coast Guard has adopted several amendments to the Inland and International Rules and Annexes which are also included in this revision This publica tion includes all revisions through 30 September 1995COMDTINST M166722C5 ORDERING INFORMATION a Following initial distribution

International Rules in this book were formalized in theConvention on the International Regulations for Preventing Collisions atSea 1972 and became effective on July 15 1977 The Rules com monly called 72 COLREGS are part of the Convention and vesselsflying the flags of states ratifying the treaty are bound to the RulesThe United States has ratified this treaty and all United States flagvessels must adhere to these Rules where applicable President GeraldR Ford proclaimed 72 COLREGS and the Congress adopted them asthe International Navigational Rules Act of 1977 The 72 COLREGS were developed by the Consultative Organization IMCO which in May 1982 wasrenamed the International Maritime Organization IMO In November1981 IMOs Assembly adopted 55 amendments to the 72 COLREGSwhich became effective on June 1 1983 The IMO also adopted 9more amendments which became effective on November 19 1989The International Rules in this book contain these amendments These Rules are applicable on waters outside of established navigational lines of demarcation The lines are called Lines and delineate those waters upon which marinersshall comply with the Inland and International Rules Lines are contained in this book iii Inland Rules The Inland Rules in this book replace the old Inland Rules WesternRivers Rules Great Lakes Rules their respective pilot rules rules and parts of the Motorboat Act of 1940 Many of theold navigation rules were originally enacted in the last provisions were added to cope with the of water transportation Eventually the navigation rules forUnited States inland waterways became such a confusing patchwork ofrequirements that in the 1960s several attempts were made to reviseand simplify them These attempts were not successful Following the signing of the Convention on the for Preventing Collisions at Sea 1972 a new effort wasmade to unify and update the various inland navigation rules Thiseffort culminated in the enactment of the Inland Navigational RulesAct of 1980 This legislation sets out Rules 1 through 38 the mainbody of the Rules The five Annexes were published as regulationsIt is important to note that with the exception of Annex V to the InlandRules the International and Inland Rules and Annexes are very similar in both content and format The effective date for the Inland Navigation Rules was December241981 except for the Great Lakes where the effective date wasMarch 1 1983 ivNAVIGATION INTERNATIONAL General PART AGENERAL RULE 1 Application a These Rules shall apply to all vessels upon the high seas andin all waters connected
