Expert Answer:

ship is made of metal which is denser than water but its hull is filled with air with is extremely less dense than water that makes up for the density of the metal and ends up being less than water.

the ship displaces as much water as it weighs. it floats providing it is not submerged before it displaces this weight.
a metal ( like coin, bolt etc) dont displaces water equal to its weight so the sinks
