Why do ships have these secret doors? Because, if these doors are not closed properly, water can enter and the entire ship can sink. So why are these doors placed on ships?

Have you ever wondered, why do huge ships have these secret doors? Such a big ship, and inside it is a secret door! It is surprising to think about it. Because, if these doors are not closed properly, water can enter and the entire ship can sink. So why are these doors placed on ships?

Actually, there is a special reason behind this. These doors are called 'pilot doors'. Many people may understand from the name that these doors are for pilots. But these pilots do not fly planes, they help in sailing ships.

When a ship enters a new or unfamiliar sea, an experienced pilot is called aboard. These pilots have special knowledge about the depth of the sea, the nature of the waves, the speed of the current, etc. But due to the height of the huge ship and the waves of the sea, boarding the ship is not an easy task. Pilot doors are used to solve this problem. Pilots can easily enter the ship through this door. Although this method seems easy, it also involves several risks.

A ship floating in the sea is seen to be lowered by about 10-12 feet. During this raising and lowering, some water enters through the ship's door. This may raise the question in your mind, will the ship sink if so much water enters? The answer is no. The ship is designed in such a way that this water exits through the bottom. This is a kind of safety measure. However, this task is not very easy for pilots. They face many challenges due to the impact of the waves, the raising and lowering of the ship. Sometimes their lives can also be in danger. But since it is difficult to safely reach the destination without a local pilot, it is very important to have this door.

Another interesting thing is that the pilot doors of the ship are a type of secret door that is usually not visible. They are hidden in the design of the ship in such a way that even if you look very carefully, many people will not notice their existence. These doors are used only for special needs. Imagine how difficult it would be for huge ships to enter a new port without such a door! These secret doors help ships to anchor in different places easily.
