Deep-draft vessels using dredged [[Page 520]] channels and propelled by mechanical power at a speed greater than five miles per hour may proceed directly through the danger zones without restriction except when especially notified to the contrary. Unless instructed to the contrary by the patrol boat, small craft navigating up or down the Potomac River during firing hours shall proceed outside of the northeastern boundary of the Middle Danger Zone. All craft desiring to enter the Middle Danger Zone when proceeding in or out of Upper Machodoc Creek during firing hours will be instructed by the patrol boat; for those craft which desire to proceed in or out of Upper Machodoc Creek on a course between the western shore of the Potomac River and a line from the Main Dock of the Naval Surface Weapons Center to Line of Fire Buoy P, clearance will be granted to proceed upon request directed to the patrol boat. (iii) The regulations in this section shall be enforced by the Commander, Naval Surface Weapons Center and such agencies as he/she may designate. Patrol boats, in the execution of their mission assigned herein, shall display a square red flag during daylight hours for purposes of identification; at night time, a 32 point red light shall be displayed at the mast head.

The mouth of Accotink Bay and that portion of Pohick Bay within the danger zone will be marked by the Post Commander with suitable warning buoys. (2) The regulations. (i) When firing affecting the area is in progress, the Post Commander will post guards at such locations that the waters in the danger zone may be observed and arrange signals whereby these guards may stop the firing should any person be seen in the danger zone. When firing is in progress, the Post Commander will cause to be displayed both on the east shore of Accotink Bay at its mouth and near the danger zone boundary on Accotink Creek a red streamer which shall be visible to a person in a boat near those points. (ii) Persons desiring to cross the waters in the danger zone shall first determine whether a red streamer is displayed on the east Shore of Accotink Bay at its mouth or near the danger zone boundary on Accotink Creek. If the red streamer is displayed, it will indicate that firing is in progress and that the waters in the danger zone are covered by rifle fire, and the area shall not be entered until the streamer is lowered. (iii) The Post Commander is hereby authorized by using such agencies and equipment necessary to stop all persons and boats at the boundary of the danger zone and prohibit their crossing the area until convenient to the firing schedule to do so.
