The ships are built in drydocks which can be flooded to float the ships out.
Marbles float due to their low density relative to water, while ships float because of their shape and the principle of buoyancy. The shape of ships allows them to displace a large volume of water, which creates an upward buoyant force that supports their weight.
Because they don't sink.
Ships don't sink because they are more boant then the water they float on. Ships don't sink because they are more boant then the water they float on.
Boats or ships
Ships can be a large craft that carries a people and good over water. These forms of transportation are able to float on water.
Ships will float in fresh water as long as their density is lower than that of the water they displace. This is due to Archimedes' principle, which states that the buoyant force acting on an object in a fluid is equal to the weight of the fluid displaced by the object.

The structure of an iron ship is such that its density is less than that of water. Anything with a density less than water will float in water.
Steel ships float on water because of the principle of buoyancy. The weight of the water displaced by the ship is equal to the weight of the ship itself, causing the ship to float. The shape of the ship also plays a role in its ability to displace water and stay afloat.
Metal ships are built to float.
Boats float and ships sink based on their design and displacement of water. Boats are typically smaller and made with materials that displace enough water to keep them afloat. Ships, on the other hand, are larger and heavier, requiring a greater displacement of water to remain buoyant. If a ship takes on too much water or has a design flaw that affects its buoyancy, it may sink.
