Density.
A large steel vessel is full of air. So its overall density is less than the equivalent amount of water that it displaces (pushes aside).

'Buoyancy' is the name given to the force exerted upwards on an object when it is immersed in a fluid. The buoyant force is exactly equal to the mass of the fluid displaced times the acceleration of gravity. If the buoyant force is greater than the mass of the object times the acceleration of gravity (F = ma), then the object floats. If the buoyant force is less, the object sinks. In the case of a ship, it displaces a greater mass of water than the mass of the ship. (Remember that one cubic meter of water is one metric ton, or about 2200 pounds)
