Art. 7.—Ships, whether steamships or sailing-ships, when at anchor in roadsteads or fairways, shall, between sunset and sunrise, exhibit where it can best be seen, but at a height not exceeding twenty feet above the hull, a white light in a globular lantern of eight inches in diameter, and so constructed as to show a clear, uniform, and unbroken light visible all around the horizon, and at a distance of at least one mile.
LIGHTS FOR PILOT-VESSELS.
Art. 8.—Sailing pilot-vessels shall not carry the lights required for other sailing-vessels, but shall carry a white light at the masthead, visible all around the horizon; and shall also exhibit a flare-up light every fifteen minutes.
LIGHTS FOR FISHING-VESSELS AND BOATS.
Art. 9.—Open fishing-boats and other open boats shall not be required to carry side-lights required for other vessels, but shall, if they do not carry such lights, carry a lantern having a green slide on the one side, and a red slide on the other side; and, on the approach of or to other vessels, such lantern shall be exhibited in sufficient time to prevent collision; so that the green light shall not be seen on the port side, nor the red light on the starboard side. Fishing-vessels and open boats when at anchor, or attached to their nets, and stationary, shall exhibit a bright white light. Fishing-vessels and open boats shall, however, not be prevented from using a flare-up light in addition, if considered expedient.
