Okay kiddo, let's talk about what defensively equipped merchant ships are. Imagine you have a big boat, like a pirate ship, but instead of looking for treasure, this boat is carrying lots of things, like food, clothes, and toys to different places. We call this boat a merchant ship.
Now, sometimes when the merchant ship is traveling in the ocean, there might be bad guys who want to take the things on the ship. These bad guys are called pirates, and they usually have their own boats, like the pirate ship we talked about earlier.
To keep the things on the merchant ship safe from the pirates, some merchant ships are equipped with special defenses. These defenses are things like big water cannons, nets, and sometimes even guns. Just like superheroes have special tools to help them fight bad guys, these defensive tools help the merchant ship protect itself from the pirates.
Now, these defensive tools don't usually hurt people, but they can make it hard for pirates to get onto the ship. It's kind of like when you try to catch a ball that's being thrown really fast at you, it's hard to grab it because it's moving too quickly. The defensive tools on the merchant ship make it hard for the pirates to catch the ship and take the things on it.
So, there you have it, defensively equipped merchant ships are just like regular merchant ships, but they have special tools to protect themselves from bad guys who want to take the things on the ship.
