§ 95.07 Vessels meeting at confluence of two rivers.

When two steam vessels meet at the confluence of two rivers, the steam vessel which has the other to port shall give the first signal; but in no case shall pilots on steam vessels attempt to pass each other until there has been a thorough understanding as to the side each steam vessel shall take.

§ 95.09 Danger and cross signals.

(a) The alarm or danger signal shall consist of four or more short and rapid blasts. Steam vessels are forbidden to use what has become technically known among pilots as "cross signals," that is, answering one whistle with two, and answering two whistles with one. In all cases and under all circumstances, a pilot receiving either of the whistle signals provided in the rules in this part with which, for any reason, he deems it injudicious to comply, instead of answering it with a cross signal, shall at once observe the provisions of this section.

(b) The pilot of any steam vessel shall sound the alarm or danger signal whenever required by the law, or any of the regulations hereinafter contained; that is to say, as follows:

(1) Whenever it is dangerous to take the side indicated by the passing signal of another vessel; or,

(2) Whenever any steam vessel does not understand or is in doubt regarding the signal of another steam vessel; or,

(3) Whenever, from any cause, one steam vessel is imperiled by another. § 95.11 Narrow channels.

When two steam vessels are about to enter a narrow channel at the same

time, the ascending steam vessel shall be stopped below such channel until the descending steam vessel shall have passed through it; but should two steam vessels unavoidably meet in such narrow channel, then it shall be the duty of the pilot of the ascending steam vessel to make the proper signals, and when answered the ascending steam vessel shall lie as close as possible to the side of the channel and either stop the engines or move them so as to give the boat only steerageway; and the pilot of the descending steam vessel shall cause his steam vessel to be worked slowly until he has passed the ascending steam vessel.

§ 95.13 Approaching bridge span or draw. (a) When two steam vessels are approaching a bridge span or draw from opposite directions and the passing signals have been given and understood, should the pilot of the descending steam vessel deem it dangerous for the steam vessels to pass each other between the piers of such span or draw, he shall sound the alarm or danger signal, and it shall then be the duty of the pilot of the ascending steam vessel to answer with a similar alarm signal, and to slow or stop his engines below such span or draw until the descending steam vessel shall have passed.

(b) If the ascending steam vessel is already in the bridge span or draw, and the descending steam vessel sounds the danger or alarm signal, it shall be the duty of the ascending steam vessel, if practicable, to drop below the bridge span or draw, and wait until the other steam vessel shall have passed.

§ 95.15 Ascending, descending steam vessels crossing river.

The pilot of an ascending steam vessel shall in no case attempt to cross the river when an ascending or descending steam vessel shall be so near that it would be possible for a collision to ensue therefrom; and conversely, the pilot of a descending steam vessel shall in no case attempt to cross the river when an ascending or descending

steam vessel shall be so near that it would be possible for a collision to ensue therefrom.

§ 95.17 Overtaking situation.

When two steam vessels are in the overtaking situation, it is the duty of the steam vessel being overtaken to answer immediately a passing signal of the overtaking steam vessel, either by assenting with the same number of blasts or by dissenting with the danger signal.

§ 95.19 Passing signals.

The passing signals, by the blowing of the whistle, shall be given and answered by pilots, in all weathers, when approaching each other; and, wherever possible, the signals shall be given and answered before the steam vessels, or if towboats pushing tows, the head of such tows, have arrived at a distance of half a mile of each other.

§ 95.21 Visual signals.

All whistle signals shall be further indicated by a visual signal consisting of an amber colored light so located as to be visible all around the horizon for a distance of not less than one mile. This light shall be so devised that it will operate simultaneously and in conjunction with the whistle sounding mechanism, and remain ignited or visible during the same period as the sound signal: Provided, That the installation, use, or employment of the amber visual signal required by this section shall be optional in the case of (a) vessels operating upon the Gulf Intracoastal Waterway; (b) vessels operating on the Mississippi River below mile 237 AHP (Belmont Landing) as set forth in map No. 40, "Maps of the Mississippi River, Cairo, Illinois, to the Gulf of Mexico, Louisiana (1944 ed.),” published by the Mississippi River Commission; (c) newly constructed vessels while en route from point of construction to a point in waters where the aforementioned amber visual signal is not required; (d) motorboats of class A and class 1; and (e) motorboats of class 2 and class 3 not engaged in trade or commerce.

§ 95.26 Warning signals for Coast Guard vessels while handling or servicing aids to navigation.

(a) Coast Guard vessels while engaged in handling or servicing an aid to navigation during the daytime may display from the yard two orange and white vertically striped balls in a vertical line not less than three feet nor more than six feet apart, and during the nighttime may display, in a position where they may best be seen, two red lights in a vertical line not less than three feet nor more than six feet apart.

(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.

[CGFR 51-26, 16 FR 5767, June 16, 1951]

LIGHTS FOR FERRYBOATS AND BARGES § 95.27 Lights for ferryboats.

(a) The signal lights on ferryboats shall be the same as those of similar

steamboats, except that double-end ferryboats shall carry a central range of clear, bright, white lights, showing all around the horizon, placed at equal altitudes forward and aft, also on the starboard side a green light, and on the port side a red light, of such character as to be visible on a dark night with a clear atmosphere at a distance of at least 3 miles, and so constructed as to show a uniform and unbroken light over an arc of the horizon of 10 points of the compass, and so fixed as to throw the light from right ahead to 2 points abaft the beam on their respective sides.

(b) The green and red lights shall be fitted with inboard screens projecting at least 3 feet forward from the lights, so as to prevent them from being seen more than half a point across the bow.

(c) Officers in Charge, Marine Inspection, in districts having ferryboats shall, whenever the safety of navigation may require, designate for each line of such boats a certain light, white or colored, which shall show all around the horizon, to designate and distinguish such lines from each other, which light shall be carried on a flagstaff amidships 15 feet above the white range lights.

§ 95.29 Lights for barges towed ahead or alongside.

(a) When one or more barges are being towed by pushing ahead of a steam vessel, or by a combination of pushing ahead and towing alongside of a steam vessel, such tow must be lighted by a flashing yellow light at the extreme forward end of the tow, so placed as to be as nearly as practicable on the centerline of the tow, a green light on the starboard side of the tow, so placed to mark the maximum projection of the tow to starboard, and a red light on the port side of the tow, so placed as to mark the maximum projection of the tow to port.

(b) When one or more barges are being towed alongside a steam vessel, there shall be displayed a white light at each outboard corner of the tow. If

the deck, deck house, or cargo of such barge obscures the sidelight of the towing steam vessel, such barge shall also carry a green light upon the starboard side when being towed on the starboard side of a steam vessel; or shall carry a red light on the port side of the barge when being towed on the port side of the steam vessel. If there is more than one such barge being towed abreast, the appropriate colored sidelight shall be displayed from the outer side of the outside barge.

(c) The colored side lights shall be so constructed as to show a uniform and unbroken light over an arc of the horizon of 10 points of the compass, so fixed as to show the light from right ahead to 2 points abaft the beam on their respective sides and of such a character as to be visible at a distance of at least 2 miles, and shall be fitted with inboard screens so as to prevent either light from being seen more than half a point across the centerline of the tow.

(d) The flashing yellow light must— (1) Be visible on a dark night with a clear atmosphere at a distance of at least 2 miles;

(2) Flash 50 to 70 times per minute; and

(3) Be constructed to show a uniform light over an arc of the horizon from right ahead to at least 90 degrees, but no more than 112.5 degrees on each side of the tow.

(e) The white lights shall be so constructed and so fixed as to show a clear, uniform, and unbroken light all around the horizon, and of such a character as to be visible at a distance of at least 2 miles.

(f) All the lights shall be carried at approximately the same height above the surface of the water and shall be so placed with respect thereto as to be clear of and above all obstructions which might tend to interfere with the prescribed arc or distance of visibility.
