float or sink
Why explain why large ships float instead of sinking?

Large ships are filled with air. The bouyant force of air is greater than the sinking force of the ship. This keeps the ship afloat. If the air compartments fill with water, the bouyancy of air goes away and the ship sinks.
They are filled with air which allows them to float. If they are made of wood it helps too. Wood floats hence the ship will float if its not too heavy.
There is air inside the ship which makes the buoyant force more. The ship has compartments, and if they fill up with water then the boat shall sink. If you watch Titanic, Mr. Andrews explains it pretty well. That's where i learned it from.
The ship has a large area. This lessens the density. Ship's also have a large volume filled with air. Air weighs less than water so the ship floats. These two factors keep the ship afloat.

Large ships have a lot of buoyancy. The buoyant force is very great and keeps it afloat. There is air in the boat to keep it floating.
