content: No one was allowed out of their cabins at all  That sounds like a major safety issue to me. If I were on that cruise I'd want to stay up near the liferafts until things calmed down.  All you see is stars in 3D, and the eternal blackness of the water below. Total blackness outstreaching forever  Yeah, I went swimming off a boat in the middle of the sea once, miles away from land. It was a pretty blue disk when I was on the deck, but the moment I hit the water the illusion was broken, I could feel the abyss under my feet. I checked the propellor like I was supposed to (it was fine) and got the hell out of there. Still gives me the shivers.
