Function: Online function code: information Role: inapplicable Presentation form: Presentation form code: mapDigital Abstract: U.S. collision regulation boundaries are lines of demarcation delineating those waters upon which mariners shall comply with the International Regulations for Preventing Collisions at Sea, 1972 (72 COLREGS) and those waters upon which mariners shall comply with the Inland Navigation Rules. The waters inland of these lines are subject to the Inland Navigation Rules Act of 1980. The waters outside these lines are subject to the International Navigation Rules of the International Regulations for Preventing Collisions at Sea, 1972 (COLREGS). The Coast Guard has the legal authority to effect regulatory changes to COLREGS. Creation of features was interpreted from descriptions published in the Code of Federal Regulations Title 33, Part 80. Purpose: To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act.
