10. Authority.—
While a pilot is on board he has absolute and exclusive authority in the absence of the master, and, probably, ranks the master when he is present. The authorities are not plain or satisfactory on this point, but there ought not to be any divided authority, particularly in such navigation as that for which the law requires the employment of a pilot. Unless the master retains, or reassumes, charge of the ship, the pilot has exclusive control and all are bound to obey his orders; he is an officer of the ship within the meaning of the statutes in regard to revolts and mutinies. But the master's authority is not annulled and it would be his duty to interfere in case of gross ignorance or palpable mistake on the part of the pilot.
Thus, in the case of the China, 7 Wall. 53, where the pilot was employed under a compulsory pilot law, the Court said:
It is the duty of the master to interfere in cases of the pilot's intoxication or manifest incapacity, in cases of danger which he does not foresee, and in all cases of great necessity. The master has the same power to displace the pilot that he has to remove any subordinate officer of the vessel. He may exercise it or not, according to his discretion.
In Ralli v. Troop, 157 U. S. 386, Justice Gray said:
To the pilot, therefore, temporarily belongs the whole conduct of the navigation of the ship, including the duty of determining her course and speed, and the time, place and manner of anchoring her. But the master still has the duty of seeing to the safety of the ship, and to the proper stowage of the cargo. For instance, the duty to keep a good lookout rests upon the master and crew. And it has been held by Dr. Lushington, in the English High Court of Admiralty, that, although a pilot is in charge, the trim of the ship is within the province of the master; as well as the duty, if two vessels entangled together, to cut away part of the rigging of his vessel, when necessary, in order to avoid a collision, or to lessen its effect, because the vessel, the judge said, "was not under orders of the pilot for this purpose; she was only under the pilot's directions for the purpose of navigation; and the master, in a case of this description, is not to wait for the pilot's directions, which would tend to create great confusion and delay."
