less than 15 feet above the deck, and in such position as may best be seen from all directions.

All the lights required by these special rules for dredges, wrecking boats, lighters, etc., shall be of such size and character as to be visible on a dark night with a clear atmosphere for a distance of at least 2 miles.*t

Vessels

201.6 Rule 6. Vessels which are moored or at anchor. of more than 300 gross tons propelled by machinery when moored or anchored in a fairway or channel where traffic is liable to congestion or confusion shall display between sunrise and sunset on the forward part of the vessel where it can best be observed from other vessels one black ball or shape not less than 2 feet in diameter.*t

201.7 Rule 7. Lights to be displayed on pipe lines; floodlights. Pipe lines attached to dredges, and either floating or supported on trestles, shall display by night one row of white lights not less than 8 feet nor more than 12 feet above the water, about equally spaced and in such number as to mark distinctly the entire length and course of the line, the intervals between lights where the line crosses navigable channels to be not more than 30 feet. There shall also be displayed on the shore or discharge end of the line two red lights, 3 feet apart, in a vertical line with the lower light at least 8 feet above the water, and if the line is to be opened at night for the passage of vessels a similar arrangement of lights shall be displayed on each side of the opening. The light shall be of the same size and character as specified in § 201.5.*t

201.8 Rule 8. Passing signals. Vessels intending to pass dredges or other types of floating plant working in navigable channels, when within a reasonable distance therefrom and not in any case over a mile, shall indicate such intention by blowing the passing signal prescribed in the local pilot rules for vessels under way, which shall be answered in the usual manner from said plant if the channel is clear and the approaching vessel may pass on the course indicated; otherwise the floating plant shall sound the alarm or danger signal and the approaching vessel shall slow down or stop and await further signal from the plant.

When the pipe line from a dredge crosses the channel in such a way that an approaching vessel, owing to excessive draft or for other reasons, cannot pass around the pipe line or dredge, a signal shall be given from the vessel by sounding four blasts of the whistle, which shall be answered by a like signal from the dredge. The pipe line shall then be opened for the passage of the vessel as soon as practicable; when the line is open ready for passage, the dredge shall so indicate by sounding the usual passing signal, and the approaching vessel shall promptly pass the dredge.**

201.9 Rule 9. Speed of vessels passing floating plant working in channels. Steamers, with or without tows, passing floating plant working in channels shall reduce their speed sufficiently to insure the safety of both the said plant and themselves, and when passing within 200 feet of the said plant their speed shall not exceed 5 miles per hour. While passing over lines of the said plant, propelling machinery shall be stopped.*+

201.10 Rule 10. Light-draft vessels passing floating plant. Vessels whose draft permits shall keep outside of the buoys marking the ends of mooring lines of floating plant working in channels.*+

201.11 Rule 11. Aids to navigation marking floating plant moorings. Breast, stern, and bow anchors of floating plant working in navigable channels shall be marked by barrel or other suitable buoys. By night approaching vessels shall be shown the location of adjacent buoys by throwing a suitable beam of light from said plant on the buoys until the approaching vessel has passed, or the buoys may be lighted by red lights visible in all directions, of the same size and character as specified in § 201.5: Provided, That the foregoing provisions of this section shall not apply to the following waters of New York Harbor and adjacent waters; namely, the East River, the North River (Battery to Spuyten Duyvil), the Harlem River, and the New York and New Jersey Channels (from the Upper Bay through the Kill van Kull, Newark Bay, Arthur Kill, and Raritan Bay to the Lower Bay).**

201.12 Rule 12. Obstruction of channel by floating plant. Channels shall not be unnecessarily obstructed by any dredge or other floating plant. While vessels are passing such plant all lines running therefrom across the channel on the passing side which may interfere with or obstruct navigation shall be slacked to the bottom of the channel.*t

201.13 Rule 13. Protection of marks placed for the guidance of floating plant. Vessels shall not run over anchor buoys, or buoys, stakes, or other marks placed for the guidance of floating plant working in channels; and shall not anchor on the ranges of buoys, stakes, or other marks placed for the guidance of such plant.*t

NOTE: If it is necessary to prohibit or limit the anchorage or movement of vessels within certain areas in order to facilitate the work of improvement, application should be made through official channels for establishment by the Secretary of War of special or temporary regulations for this purpose.

201.14 Rule 14. Clearing of channels. When special or temporary regulations have not been prescribed and action under these rules and regulations will not afford clear passage, floating plant in narrow channels shall, upon notice, move out of the way of vessels a sufficient distance to allow them a clear passage. Vessels desiring passage shall, however, give the master of the floating plant ample notice in advance of the time they expect to pass.**

201.15 Rule 15. Revocation of conflicting regulations. All regulations or parts of regulations in conflict with these regulations are hereby revoked.*t
