XV. Rules of the Road
There are three general bodies of rules covering the navigation of vessels with respect to the rules of the road.
The first of these are the International Rules which were adopted at a conference of maritime nations held in the United States in 1889, which are now in force in practically all maritime countries. They apply only to vessels on the high seas, the boundary line of which, so far as the United States is concerned, has been defined by an act of Congress passed in 1913, under which the Secretary of Commerce, having been authorized to fix lines separating the high seas from inland waters for the purposes of the rules of the road, has defined a water line from Cutler Harbor, Maine, to Puget Sound.
The second body of rules is known as the Inland Rules, embodied in a federal statute passed in 1897, and applicable only to the waters within the line thus defined. These rules, generally speaking, are similar to the International Rules but differ in a number of details.
The third body of rules is what is known as the Pilot Rules for certain inland waters of the Atlantic and Pacific coasts and of the coast of the Gulf of Mexico, adopted by the supervising inspectors of the Steamboat Inspection Service, approved by the Secretary of Commerce under authority of the Act of June, 1897, establishing the Inland Rules, and of subsequent acts passed in 1903 and 1913, establishing the Department of Commerce. These rules are also to a large extent similar to, and are generally in harmony with the inland rules, to which they yield in case of conflict. More extended reference to these rules, the knowledge of which should be a matter of second nature to seafaring men, is beyond the scope of this summary.
