It suddenly dawned on me that on a cruise ship, it's likely impossible to hang a line array or similar PA given the roll of the ship and the constraints of swing space. Does anyone know what is actually used? Is it something in wall, or is it something else? I was on a Royal Caribbean cruise a while back and I know their rigs were 100% EAW, so I'm trying to think of how they managed it. Specific ship class would be the Royal Caribbean Voyager.
