The Archimedian principle explains the bounce force of any object, pertially immersed or totally immersed in a fluid is buoyed up by a force equals to the weight of the fluid the object displaces. Ships design allows very large weight shops to float just by displacing a quantity of water of more weight more than the weight of the ship. Since the Hull of the ship is designed to take this to account, more weight added will increase the gravity force acting on it and this causes the Hull to dip lower into water leading it to displace more water and increases the strength of it Giant force. This two forces mentioned Wil cancel each other, this makes the ship floats....THEREFORE Balance of forces involved is called STATE OF EQUILIBRIUM.....
