Hey,
Because of buoyancy. A needle cannot stay afloat bcause the mass of water removed by it is lesser than the mass of needle itself. But the volume if a ship is much bigger, so the mass of water removed by it is greater than that of ship. The removed water creats an upward force on the object immersed in a fluid, which has to be greater that the weight of the object itself to make it float. In this case this it is greater in ship made of iron. That is why the bottom part of a ship is wide.
HOPE IT HELPS:-))

This is mainly due to the density and the surface area , the ships have large surface area , as we know pressure is inversely proportional to area so as more is the surface area, less would be the pressure and vice versa. That's why nail, having less surface area sinks due to more pressure
