Which of the following statements is true about using your amateur radio license when operating aboard a vessel or craft in international waters?

When you are aboard a US-documented vessel in international waters, the vessel is essentially considered US territory for licensing purposes. This means your standard FCC amateur radio license remains valid and grants you operating privileges without the need for special marine-specific FCC paperwork. However, maritime law dictates that the ship's master (the captain) has absolute authority over the vessel, its communications equipment, and the safety of its passengers. Therefore, to prevent interference with critical ship systems, you must always obtain the master's explicit permission before installing or operating an amateur radio station on board.
