§ 80.31 Clearing of channels.

When special or temporary regulations have not been prescribed and action under the regulations contained in §§ 80.26 to 80.30, 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.

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 the Army of special or temporary regulations for this purpose.

§ 80.31a 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.

LIGHTS FOR RAFTS AND OTHER CRAFT NOT PROVIDED FOR

§ 80.32 Lights for rafts and other craft.

(a) Any vessel propelled by hand power, horse power, or by the current of the river, except rafts and rowboats, shall carry one white light forward not less than 8 feet above the surface of the water.

(b) Any raft while being propelled by hand power, by horse power, or by the current of the river, while being towed, or while anchored or moored in or near a channel or fairway, shall carry white lights as follows:

(1) A raft of one crib in width shall carry one white light at each end of the raft.

(2) A raft of more than one crib in width shall carry 4 white lights, one on each outside corner.

(3) An unstable log raft of one bag or boom in width shall carry at least 2 but not more than 4 white lights in a fore and aft line, one of which shall be at each end. The lights may be closely grouped clusters of not more than 3 white lights rather than single lights.

(4) An unstable log raft of more than one bag or boom in width shall carry 4

white lights, one on each outside corner. The lights may be closely grouped clusters of not more than 3 white lights rather than single lights.

(c) The white lights required by this section shall be carried from sunset to sunrise, in a lantern so fixed and constructed as to show a clear, uniform, and unbroken light, visible all around the horizon, and of such intensity as to be visible on a dark night with a clear atmosphere at a distance of at least one mile. The lights for rafts shall be suspended from poles of such height that the lights shall not be less than 8 feet above the surface of the water, except that the lights prescribed for unstable log rafts shall not be less than 4 feet above the water.

SPECIAL DAY OR NIGHT SIGNALS

§ 80.32a Day marks for fishing vessels with gear out.

All vessels or boats fishing with nets or lines or trawls, when under way, shall in daytime indicate their occupation to an approaching vessel by displaying a basket where it can best be seen. If vessels or boats at anchor have their gear out, they shall, on the approach of other vessels, show the same signal in the direction from the anchor back towards the nets or gear.

[CGFR 49-39, 14 F.R. 6517, Oct. 26, 1949] § 80.33 Special signals for vessels employed in hydrographic surveying.

By day a surveying vessel of the Coast and Geodetic Survey, under way and employed in hydrographic surveying, may carry in a vertical line, one over the other not less than 6 feet apart where they can best be seen, three shapes not less than 2 feet in diameter of which the highest and lowest shall be globular in shape and green in color and the middle one diamond in shape and white.

(a) Vessels of the Coast and Geodetic Survey shall carry the above-prescribed marks while actually engaged in hydrographic surveying and under way, including drag work. Launches and other boats shall carry the prescribed marks when necessary.

(b) It must be distinctly understood that these special signals serve only to indicate the nature of the work upon which the vessel is engaged and in no way give the surveying vessel the rightof-way over other vessels or obviate the necessity for a strict observance of the rules for preventing collisions of vessels.

(c) By night a surveying vessel of the Coast and Geodetic Survey, under way and employed in hydrographic surveying, shall carry the regular lights prescribed by the rules of the road.

(d) A vessel of the Coast and Geodetic Survey, when at anchor in a fairway on surveying operations, shall display from the mast during the daytime two black balls in a vertical line not less than 6 feet apart. At night two red lights shall be displayed in the same manner. In the case of a small vessel the distance between the balls and between the lights may be reduced to not less than 3 feet if necessary.

(e) Such vessels, when at anchor in a fairway on surveying operations, shall have at hand and show, if necessary, in order to attract attention, a flare-up light in addition to the lights which are, by this section, required to be carried.

(b) Vessels, with or without tows, passing Coast Guard vessels displaying this signal, shall reduce their speed sufficiently to insure the safety of both vessels, and when passing within 200 feet of the Coast Guard vessel displaying this signal, their speed shall not exceed 5 miles per hour.
