PILOT RULES FOR THE RIVERS WHOSE WATERS FLOW
Rules and regulations for the government of pilots of vessels propelled
by steam, gas, fluid, naphtha, or electric motors and of other vessels propelled by machinery, navigating the Red River of the North, the Mississippi River, and other rivers emptying into the Gulf of Mexico, and their tributaries, as amended by the Board of United States Supervising Inspectors, Steamboat Inspection Service, February 18, 1911, and approved by the Secretary of Commerce, under the authority of section 4412, Revised Statutes of the United States. These rules have been signed by the members of the Board of Supervising Inspectors, as required by section 4412, Revised Statutes.
THESE RULES SHALL BE EFFECTIVE ON AND AFTER APRIL 1, 1911.
RULES FOR VESSELS PASSING EACH OTHER.
In the following rules the words steam vessel and steamer shall include any vessel propelled by machinery.
Risk of collision can, when circumstances permit, be ascertained by carefully watching the compass bearing of an approaching vessel. If the bearing does not appreciably change, such risk should be deemed to exist.
RULE I. When steamers are APPROACHING EACH OTHER FROM OPPOSITE DIRECTIONS, the signals for passing shall be one short and distinct blast of the whistle to alter course to starboard so as to pass on the port side of the other, and two short and distinct blasts of the whistle to alter course to port so as to pass on the starboard side of the other.
When two steamers are meeting end on, or nearly end on, so as to involve risk of collision, the helms of both shall be put to port, so that each may pass on the port side of the other.
When an ascending steamer is approaching a descending steamer, the pilot of the ascending steamer shall give the first signal for passing, which shall be promptly answered by the same signal by the pilot of the descending steamer, if safe to do so, and both shall be governed accordingly; but if the pilot of the descending steamer deems it dangerous to take the side indicated by the ascending steamer, he shall immediately signify that fact by sounding the alarm or danger signal of four or more short and rapid blasts of the whistle, and it shall be the duty of the pilot of the ascending steamer to answer by a signal of four or more short and rapid blasts of the whistle, and the engines of both steamers shall be immediately stopped, and backed if necessary, until the signals for passing are given and answered. After sounding the alarm signal by both steamers, the pilot of the descending steamer shall indicate by his whistle the side on which he desires to pass, and the pilot of the
ascending steamer shall govern himself accordingly, the descending steamer being entitled to the right of way.
Where possible, the signals for passing must be made, answered, and understood before the steamers have arrived at a distance of half a mile of each other.
Provided, however, That when a steamer on the Mississippi River is about to enter the Ohio River at the same time that a steamer on the Ohio River is about to enter the Mississippi River, at Cairo Point, the steamer on the Mississippi River shall give the first signal; but in no case shall pilots on steamers attempt to pass each other until there has been a thorough understanding as to the side each steamer shall take.
RULE II. If from any cause the signals for passing are not made at the proper time, as provided in Rule 1, or should the signals be given and not properly understood, from any cause whatever, and either steamer become imperiled thereby, the pilot on either steamer may be the first to sound the ALARM OR DANGER SIGNAL, which shall consist of four or more short and rapid blasts of the whistle. Whenever the danger signal is given, the engines of both steamers shali be stopped and backed until the headway of the steamers has been fully checked; nor shall the engines of either steamer be again started ahead until the steamers can safely pass each other. Steamers approaching each other from opposite directions 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, à pilot receiving either of the whistle signals provided in the rules, which for any reason he deems injudicious to comply with, instead of answering it with a cross signal, shall at once observe the provisions of this rule.
RULE III. When two steamers are about to enter a NARROW CHANNEL at the same time, the ascending steamer shall be stopped below such channel until the descending steamer shall have passed through it; but should two steamers unavoidably meet in such channel, then it shall be the duty of the pilot of the ascending steamer to make the proper signals, and when answered, the ascending steamer shall lie as close as possible to the side of the channel the exchange of signals may have determined, as provided by Rule I, and either stop the engines or move them so as only to give the boat steerageway, and the pilot of the descending steamer shall cause his steamer to be worked slowly until he has passed the ascending steamer.
RULE IV. When two steamers are approaching a BRIDGE SPAN OR DRAW from opposite directions and the passing signals as provided in Rule I have been given and understood, should the pilot of the descending steamer deem it dangerous for the steamers 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 steamer to answer with a similar alarm signal, and to slow or stop his engines below such span or draw until the descending steamer shall have passed.
RULE V. When a steamer is ascending and RUNNING CLOSE ON A BAR OR SHORE, the pilot shall in no case attempt to cross the river when a descending steamer shall be so near that it would be possible for a collision to ensue therefrom.
