Maritime flag

Ahoy, little one! Have you ever seen big ships sailing across the ocean with colorful flags waving on them? Well, those flags are called maritime flags!

Maritime flags are used by ships to communicate with each other. These flags are made up of different colors and shapes, which represent different letters and phrases in a code language called the International Code of Signals. It's like a secret code that helps sailors talk to each other without using words.

For example, if a ship wants to say "I am maneuvering with difficulty," they will raise a yellow flag with a black square in the middle. If they want to let another ship know that they are towing something, they will raise a blue flag with a white diamond.

These flags are very important for the safety and navigation of ships. It helps them to know what other ships nearby are doing and avoid any accidents.

So, the next time you see a big ship with colorful flags, you will know that they are communicating with other ships using a special code language called the International Code of Signals. Pretty cool, right?
