ELI5:please explain how cruise ships are able to stay upright and not tip over in high winds, when many other smaller boats experience great sway.

keeping center of gravity low is important to shipbuilding so how do these super cruise ships stay upright in high winds when they are 5+ stories tall above the water?

Tons of weight concentrated in the lower portion. The upper decks consist of far more empty space than the lower ones. To tip the ship, wind would need to lift that weight upward, which would take an enormous amount of force.
