It basically wants to push (displace) water away from underneath it. Since the volume of water is always much larger than the actual ship, it will never be able to displace enough water to sink. That is - unless it's damaged below the water-line so water can flood in.
The force that helps a ship float is the buoyant force. The buoyant force is exerted by a fluid upwards that opposes the weight of the object immersed.
Just like any other object, a ship will float if it has less density than the liquid on which it is supposed to float. Density = mass / volume; in the case of a ship, that includes the volume of the ship plus any air trapped inside.

Gravity makes a ship float. Gravity pulls harder on the mass of water than the air inside the ship. In this way the water is pulled under the ship, instead of the ship being pulled under the water.

An object will float on water if it has less density than the water.
buoyancy
An object will float if it has a density that is less than that of water. Or whatever liquid it is placed on. In the case of a ship, that includes not just the steel, but the entire ship - including air trapped inside the ship.
the air inside the can keeps it afloat
