ART. 8. Pilot vessels when engaged on their station on pilotage duty shall not show the lights required for other vessels, but shall carry a white light at the masthead, visible all around the horizon, and shall also exhibit a flare-up light or flare-up lights at short intervals, which shall never exceed fifteen minutes.
On the near approach of or to other vessels they shall have their side lights lighted, ready for use, and shall flash or show them at short intervals to indicate the direction in which they are heading; but the green light shall not be shown on the port side nor the red light on the starboard side.
A pilot vessel of such a class as to be obliged to go alongside of a vessel to put a pilot on board may show the white light instead of carrying it at the masthead, and may, instead of the colored lights above mentioned, have at hand, ready for use, a lantern with a green glass on the one side and a red glass on the other, to be used as prescribed above.
Pilot vessels when not engaged on their
station on pilotage duty shall
carry lights similar to those of other
vessels of their tonnage.
ART. 9. Fishing vessels and fishing boats when under way and when not required by this article to carry or show the lights therein named shall carry or show the lights prescribed for vessels of their tonnage under way.
(a) Vessels and boats when fishing with drift nets shall exhibit two white lights from any part of the vessel where they can best be seen. Such lights shall be placed so that the vertical distance between them shall be not less than 6 feet and not more than 10 feet, and so that the horizontal distance between them measured in a line with the keel shall be not less than 5 feet and not more than 10 feet. The lower of these two lights shall be the more forward, and both of them shall be of such a character as to show all around the horizon and to be visible at a distance of not less than 3 miles.
(b) Vessels when engaged in trawling,
by which is meant the
dragging of an apparatus along the bottom
of the sea—
First. If steam vessels, shall carry in the same position as the white light mentioned in article 2 (a) a tricolored lantern so constructed and fixed as to show a white light from right ahead to 2 points on each bow and a green light and a red light over an arc of the horizon from 2 points on either bow to 2 points abaft the beam on the starboard and port sides, respectively, and not less than 6 nor more than 12 feet below the tricolored lantern, a white light in a lantern so constructed as to show a clear, uniform, and unbroken light all around the horizon.
Second. If sailing vessels of 7 tons gross tonnage and upward, shall carry a white light in a lantern so constructed as to show a clear, uniform, and unbroken light all around the horizon, and shall
