People will sue for anything these days, and whatever it takes. Some crap lawyer probably contacted some passangers and said "Do you know you can sue". You can sue for whatever you want, and it is pretty sad. When on a cruise, you have to expect the unexpected, and something like this is bound to happen every once in a while. More than likely, the captain didn't have enough time to avoid the wave. As we all know, waves can cover hundreds or even thousands of miles of ocean, so getting out of the way might have not even been an option. If people do sue for that, Shame on them!!!!
