It depends on the density of a substance, if it can float or not. If its mass per volume is less than the one of water, it floats. That means overall that the same volume of water would have a bigger weight than the one of the ship... and it floats... By the way: The volume of water the ship pushes away (under the water line) while floating, has just the weight of the ship. So if you're talking about a certain water deplacement of a ship, you're actually talking about the ship's weight ;-). Vic

It can do so, because a ship is lighter than the weight of the water it displaces. As it displaces water, the pressure upwards maintains its buoyancy. Ultimately, if a ship displaces the amount of water just about equal to the weight of the ship, it will remain buoyant. However, if the ship is heavier than the water it displaces, then it will sink. This is famously known as the Archimedes Principle.

It is because the weight of the vessel and oil is less than the weight of the volume of water it displaces.

Can metal ships float?

It depends. A steel ship will float just fine, so will an iron one(i.e. Old Ironsides). It all depends on the size, weight, and buoyancy of the ship.
