The White House,
       April 5, 1917.
Regulations for carrying into effect the Executive order of the President establishing defensive sea areas, April 5, 1917.
Whereas in accordance with section forty-four of the act entitled "An act to codify, revise, and amend the penal laws of the United States," approved March fourth, nineteen hundred and nine, as amended by "An act making appropriations for the naval service for the fiscal year ending June thirtieth, nineteen hundred and eighteen, and for other purposes." approved March fourth, nineteen hundred and seventeen, defensive sea areas have been established by my order of April 5, 1017.
Now, therefore, I, Woodrow Wilson, President of the United States of America, do hereby authorize and promulgate the following orders and regulations for the government of persons and vessels within the limits of defensive sea areas, which orders and regulations are necessary for purposes of national defense:
* In the neighborhood of each defensive sea area entrances have been designated for incoming and outgoing vessels, including, in the case of areas across which more than one channel exists, an entrance for each channel. Those entrances are described in Article X of these regulations in conjunction with the areas to which they respectively pertain.
* A vessel desiring to cross a defensive sea area shall proceed to the vicinity of the entrance to the proper channel, flying her national colors, together with international code number and pilot signal and there await communication with the harbor-entrance patrol. It is expressly prohibited for any vessel to enter the limits of a defensive sea area otherwise than at a designated entrance and after authorization by the harbor-entrance patrol.
* Boats and other craft employed in the harbor-entrance patrol will be distinguished by the union jack, which will be shown from a position forward; they will also fly the usual naval pennant. At night they may show a vertical hoist of three lights—white, red, and white, in the order named.
* On receiving permission from the harbor-entrance patrol to enter a defensive sea area, a vessel must comply with all instructions as to pilotage and other matters that she may receive from proper authority, either before or during her passage across the area. It is understood that only upon condition of such compliance is the said permission granted.
* No permission will be granted to other than a public vessel of the United States to cross a defensive sea area between sunset and sunrise, nor during the prevalence of weather conditions that render navigation difficult or dangerous. A vessel arriving off a defensive sea area after sunset shall anchor or lie-to at a distance of at least a mile outside its limits until the following sunrise; vessels discovered near the limits of the areas at night may be fired upon.
* No vessel shall be permitted to proceed within the limits of a defensive sea area at a greater speed than five (5) knots per hour.
* All matters pertaining to fishery and the passage of small crafts within a defensive sea area shall be regulated by the senior officer of the harbor-entrance patrol.
* These regulations are subject to modification by the senior officer of the harbor-entrance patrol when the public interest may require, and such notification as circumstances may permit will be issued regarding modifications thus made.
* Any master of a vessel or other person within the vicinity of a defensive sea area who shall violate these regulations, or shall fail to obey an order to stop or heave-to, or shall perform any act threatening the efficiency of mine or other defenses or the safety of navigation, or shall take any action inimical to the interests of the United States in its prosecution of war, may be detained therein by force of arms and renders himself liable to prosecution as provided for in the act to codify, revise, and amend the penal laws of the United States, approved March 4, 1909, as amended by "the act making appropriations for the naval service for the fiscal year ending June 30, 1918, and for other purposes," approved March 4, 1917.
