This may seem like an odd question but what exactly can a cruise ship do to defend itself? I assume they have some kind of local police dept for the ship but they would be nothing against outside threats. Does the US Coast Guard offer any help? Aren't these cruise ships usually in waters of other countries? Are there treaties in place to allow use of certain waters for commerical use such as this. Think about it; they're pretty much sitting ducks out in the middle of no-where. My wife and I are thinking about maybe going on a cruise and my twisted mind thought of the question above. The only time I remember hearing anything like this happening is back in the 80's when some pirates attacked a cruise ship and actually killed some guy in a wheel chair and pushed him overboard.
