(a) The compensation to be paid to pilots for conducting to or from the city of Philadelphia, all dismasted or otherwise crippled vessels, which shall have been in any wise injured, so as to occasion to the said pilots any extraordinary care or trouble, shall not exceed double the amount what they otherwise would have been entitled to, of which the Board of Wardens¹ shall judge.

(b) A vessel which has suffered a casualty limiting the capabilities of its steering, propulsion or navigational equipment or which is otherwise limited by its speed, draft or other factor in its ability to navigate such that its navigation will be of extraordinary duration or will occasion its pilot extraordinary care or trouble shall be obliged to receive two licensed pilots and pay to each the full amount of pilotage required by this act. In the event that such services are provided by a single pilot, he may charge up to double the pilotage amount calculated in accordance with the rates under this act.

(c) Outbound deep draft vessels, as defined by the Navigation Commission, shall be assigned two pilots for the outbound passage, and the vessel's pilotage rate for such passage shall be doubled to account for the use of the two pilots.
