Ships float because their hulls are made from a special form of foamed steel that is lighter than water. A great amount of air is forced into the steel as it cools, generating a steel bubble lattice that on net is lighter than water. This allows steel ships to float, even though the density of solid steel is about 490 lb/ft^3, while water is 62.4 lb/ft^3.
