Thank you, Paul, for your answer. I have been curious about this for a long time, and am glad I've found a place where I could get an answer. I do have one more question: are captain's wives allowed to "live" onboard with their husbands? It must be a difficult life for a family - my cousin was captain of a cargo ship and his wife is able to spend some time aboard with him but not more than a couple weeks at a time. But his arrangement is different - six months at sea, six months at home. I am curious how the wives of cruise ship captains deal with living arrangements and separation.
Thank you for any insight.
