Basically. The weight of the ship has a center of gravity (the force that pushes the ship down) which is balanced against the center of bouyancy (the part of the ship that displaces water, which creates a force of lift). The ships hull is designed so that when center of gravity shifts in one direction (and makes the ship lean in that direction) the center of bouancy shifts in that direction as well, creating a counterforce that pushes the ship upright again.
