55 Pa. Stat. § 171
The pilot who shall first offer himself to any inward-bound ship or vessel shall be entitled to take charge thereof, except as hereinafter excepted: Provided, His license shall authorize him to pilot ships or vessels of such draught of water; and it shall be the duty of such pilot, if required so to do, to exhibit his license to the master or commander of such ship or vessel; and, in case the draught of water of such ship or vessel shall be greater than such pilot shall be licensed to carry, he may nevertheless, with the consent of the master, take charge of such ship or vessel until a pilot duly qualified shall offer. In all cases when extraordinary services have been rendered by any pilot or pilots, the said board of commissioners of navigation shall, in case the parties cannot agree, determine the compensation to be allowed for such services; and the pilot shall inform the master of every vessel he shall conduct to the port of Philadelphia of the rules and regulations necessary in reporting at the office of the president of the board of commissioners of navigation.
