i was on a cruise once... however in my experiece unless i looked out the window i couldnt tell the boat was even in water.... unless...

I stood still next to a wall i could tell... but as far as walking around hinging out... dont forget a cruise ship is what? 1,000 feet long? even big waves the ship is so big, and soo heavy, it rides on top of the big waves...

however one thing i wish i could have done was go up to the bow like in the movie Titanic, that would have been cool...

Btw if your ship sinks lol rest assured any US vessel with in like hundreds of miles will come to your recuse... even the US Navy...
