AMATEUR RADIO ON CRUISE LINES
Very few - if any - cruise lines will publicly state that amateur radio gear is welcome on passenger cruises. As we researched the sites of over 60 lines, most actually state that "amateur radio gear is prohibited" on board.
But exceptions are made daily on many aspects of your travel. If you absolutely must take your ham gear with you, then talk with your travel agent. They know the contacts to make things happen for you. Not using a travel agent? Then start with your sales agent, and work yourself up the ladder of communications for your cruise line.
If leaving territorial waters, it is entirely your responsibility to know the international laws regarding proper amateur radio operating procedures while out of your home country. First and foremost: Carry a copy of your ham radio license with you at all times. But that is NOT enough - carefully read the information on the following two Web sites and be knowledgeable about operating legally while on your cruise.
