The air in a ship is not as dense as water. That’s the thing that keeps it afloat. The density of the ship must be less than that of the water.

Why do boats float and not sink?
If an object is less than the amount of water it displaces, it will sink. A boat floats because it moves water that is heavier than the boat’s own weight.
Why do boats or ships float in water?
The principle of the net upward force on an object immersed in water is the same as the weight of the water displaced by the object, which is what makes ships float.
Does boat sink in water?
The small amount of water it displaces is not enough to make it sink. Even though it weighs a lot, a huge boat will float because of how much water it displaces.
Why do we not sink in water?
A human submerged in water is less dense than the water itself due to the fact that the lungs are full of air. If the density of the object is greater than the water, it will sink.
Why does a small pebble sink in water?
The downward pull of gravity causes objects in liquid to sink. The liquid pushes the object up with a force that is against gravity as it sinks.
Why stone sinks in water and ship floats?
The stone sinks slower than it would do through the air due to the fact that the buoyancy force is smaller than the gravity force. A ship is also affected by the two forces.
How are ships made to float?
The metal used to make ships is denser than water and therefore air-filled chambers are built into them. The ship is able to float because it is less dense than the water.
What force stops a boat from sinking?
An extra reaction force is added to the upthrust in order to balance the weight when the object is at the bottom. The object will rise if the upthrust is bigger than it is.
Why do some materials float or sink in water?
The denser the objects are, the denser the molecule dispersal is. Some things float and some sink because of their density. Some objects are denser than others and some are less dense. Air is less dense than water, so hollow things tend to float.
