Docking and Undocking
In docking the Leviathan there is no particular trick that must be known, but on undocking her it must be so timed that while on the New Jersey side at Hoboken the water is dead slack, the flood on the New York side has just begun to make. This helps the operation in two ways. First, by getting her away from the dock before the flood current begins to press her against the dock, and second when she backs out, the beginning of the flood current on the New York side assists to turn her stern upstream and operates to point her correctly. In leaving New York for sea, the ship must be manœuvered over to the New York side, the deepest water being on the New York side. In midstream and on the New Jersey side, between Hoboken and the Statue of Liberty, there is not enough water to float the Leviathan. In docking and undocking we need from fourteen to sixteen tugs. Abnormal conditions can be expected in the winter months. Upstate freshets and northerly gales sometimes operate to kill the flood current off Hoboken and to cause a continuing ebb current. Such a condition has happened, making it impossible to point the ship correctly downstream, and it has been necessary to yield to the elements and to permit her to turn the ship. There is always an apprehension in entering and leaving New York Harbor lest merchant vessels carelessly anchor themselves in the Leviathan’s fairway. Such a condition adds difficulties to the piloting of the ship.
Like most passenger vessels she is designed to have a slow and easy roll, which means that she has not a great margin of stability. In entering New York, bringing troops homeward, it is necessary to keep the troops in control and evenly distributed, because in their excitement and happiness, they tend to rush from one side to another on the passing of every cheering ferryboat, heeling over even this great ship. When this ship heels over, owing to her great beam, and to her box-like dead-flat section, it materially increases her already great draft. Large ballast tanks with suitable pumps are provided for the purpose of counteracting the tendency of the ship to heel over, but in spite of this, at sea she lies over to the breeze, and in entering New York she is very sensitive to the movement of troops about the deck.
In mooring to the buoy in Brest Harbor, it is an advantage to arrive at slack water; she must be brought to the buoy with her momentum entirely gone, for her great weight of sixty-nine thousand tons, if moving when the buoy is correctly placed, would make it impossible for the mooring party to handle the great heavy links of four-inch chain, and to connect the mooring shackle.
