Title 46 › Subtitle II — Vessels and Seamen › Part F — Manning of Vessels › CHAPTER 81 — GENERAL › § 8101
The vessel’s inspection certificate must list the number and types of licensed crew and other workers needed for safe operation, including lifeboatmen. For special ships, the list must take into account their duties: sailing school vessels must count instructors and students who help, mobile offshore drilling units need their special skills, and tank vessels must cover navigation, cargo work, and upkeep. The Secretary can change the required crew on the certificate, and decisions by an authorized official can be appealed. A ship may not operate without the crew shown on its certificate. People may not serve as or be hired as a master, mate, engineer, radio officer, or pilot unless licensed by the Secretary. Violations can bring civil penalties up to $10,000, with each day a separate offense. If a crew member is lost without the owner’s or master’s fault, the master must hire replacements of the same or higher grade if available. If the master decides the ship is safe and replacements are not available, the ship may go on, but the master must report in writing to the Secretary within 12 hours after arrival explaining each vacancy. Failing to report carries a $1,000 penalty for each missing position. Owners, charterers, or managing operators who do not keep the required crew face a $10,000 penalty. Smaller freight vessels under 100 gross tons, small passenger vessels, and sailing school vessels that are undermanned face a $1,000 penalty, and the vessel itself can be held for the penalty. If the two next-most-senior licensed officers reasonably think the master is impaired by alcohol or drugs, the next senior licensed person must relieve the master, take command, log the incident if required, and report it to the Secretary immediately and in writing within 12 hours after arriving at the next port.
