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.
this site will help alot.

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

A boy throws a steel ball straight up. Consider the motion of the ball only after it has left the boy's hand but before it touches the ground and assume that forces exerted by the air are negligible. For these conditions, the force(s) acting on the ball is (are): a. A downward force of gravity along with a steadily decreasing upward force b. A steadily decreasing upward force from the moment it leaves the boy's hand until it reaches its highest point on the way down there is a steadily increasing downward force of gravity as the object gets closer to the earth c. Constant downward force of gravity along with an upward force that steadily decreases until the ball reaches it highest point on the way down there is only a constant downward force of gravity d. Constant downward force of gravity only
