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.
small water displacment compared to ships size
A ship can float on water because of buoyancy. The shape of the ship and the displacement of the water it pushes aside when it enters the water create an upward force that counteracts the downward force of gravity. This buoyant force allows the ship to float and support its own weight.
your ship is average size i suppose, then it depends on how much oil you have.
