The law provides that the Commissioner of Navigation shall publish annually a list of vessels of the United States belonging to the commercial marine, specifying their official number, signal letters, name, rig, tonnage, home port, and place and date of build, distinguishing sailing vessels from those propelled by steam or other motive power. The list for the year 1919 was the fifty-first list so published.
Under the provisions of an act passed in 1912 it is required that upon affidavit by a reputable ship builder as to the rebuilding of unrigged wooden vessels, giving date and place of their rebuilding, and certifying that they are sound and free from rotten wood and in every respect seaworthy, a notation to this effect shall be included in the list. It is noted that the provision applies only to unrigged wooden vessels, and thus does not cover the case of rigged barges, whatever their size.
XXIII. Numbering of Undocumented Motor Boats
In 1918 a law was passed requiring the numbering of all theretofore undocumented motor boats, except vessels under sixteen feet temporarily equipped with detachable motors. These numbers are awarded by the collectors of customs on application of the owner or master, and are required to be painted, or otherwise attached, to the bow of the vessel, and to be not less than three inches in size. Violation of the act is subject to a penalty of $10.
From the date of the passage of the act on December 7, 1917, up to July 1, 1919, nearly 100,000 such vessels had been numbered, and the experiment had proved highly successful in assisting the enforcement of the navigation laws and the collection of taxes as well as the enforcement of harbor police laws and regulations.
XXIV. Administration of Navigation Laws
Practically every department of the government has to do with some feature or other of the navigation laws as affecting ship building, maritime commerce and ocean transportation. Primarily, however, the administration of the laws is in the hands of the Department of Commerce, under the immediate direction of the Bureau of Navigation, the Steamboat Inspection Service and the United States Shipping Commissioners. Other branches of government service whose functions touch on some phase of navigation are the Public Health Service, with its hospitals and quarantine stations, and the Coast Guard which, since 1915, has included the Revenue Cutter and Life Saving Service. The War and Navy departments also have various functions related primarily to the national defense. The activities of the Shipping Board will be separately reviewed.
Commissioner of Navigation.—
The Bureau of Navigation, under the head of the Commissioner of Navigation, has general superintendence of the merchant marine and seamen so far as they are not directly subject to other departments; it controls the documentation of vessels and has supervision of the laws relating to measurement of vessels, signal numbers and the questions relating to the tonnage tax. It is charged further with the preparation of the annual list of vessels belonging to the merchant marine, has authority to change the names of vessels, and is charged with the preparation of annual reports to the Secretary, and with numerous other miscellaneous but important duties.
