9. Duties.—
The pilot is the servant of the owner, if voluntarily employed, otherwise not. Like other persons, he is answerable for any damage he may cause by negligence or default. Occupying a quasi-public position and the ship not being free to decline his services, it is his duty to render his services, when requested, to the best of his ability. If he refuses, he may be liable both civilly and criminally. The ancient sea-laws were stringent in this regard; the Laws of Oléron, for example, provide that if disaster is sustained by the ignorance of the pilot, he shall be obliged to make full satisfaction therefor, and, if he has not wherewith to make satisfaction, the master, or any one of the mariners or merchants may cut off his head and shall not be bound to answer for it. When a pilot takes charge of a vessel at sea, it is his duty to stay by her, unless discharged, until she reaches her destination or some place of safety. He is held to be able to anticipate the action of the wind and sea on boats in his charge. He must be thoroughly familiar with the topography and character of the waters for which he offers his services, and keep acquainted with all changes therein, both as to fixed and temporary landmarks and also as to the character of the bottom and presence of temporary obstructions therein.
