Under what conditions may a vessel be fined for a stowaway?

• A. When a stowaway is discovered aboard
• B. When the voyage begins
• C. When the ship leaves port
• D. Never

Answer: (A)

The key idea is that penalties for a stowaway arise when an unauthorized person is found aboard. Once a stowaway is discovered, the vessel’s operator can be fined because the ship has allowed an illegal entrant to be on board and may be responsible for failing to prevent or properly report it. This makes the discovery moment the trigger for enforcement, not the voyage starting or leaving port, and not “never.” So the best answer is that the vessel may be fined when a stowaway is discovered aboard.
