why steel boat floating water in spite of steel have density than water because steel has a density than water thus drowning if bring a steel make hitting the thin plates and make shape of a boat. Volumetric vessel is increased in spite of the same mass. The steel has a density less than water so it floats in water. the object can float in any liquid because the object is less density then liquid that object can float in water because the object has a density lass than water and water have pressure of an object to float up it is called "floating force or buoyancy force" which force this will depend on the amount of water that is the object replace it the object has an are exposed to water much the density of the object is reduced and floating force will increase the object floating in the water so if an object floating has big pad and has curved edges like a boat the object will float well
