Okay kiddo, so you know how sometimes families go on vacation and they take a big RV or camper with them so they can have a comfortable place to sleep and eat while they travel? Well, sometimes really rich people have big boats called yachts, and they want to take them on vacations too, but they can't always drive them to where they want to go because it might be too far away or the ocean might not be safe to sail on.
So, what they do is hire a special company that can transport their yacht for them. Just like how a big truck can carry a lot of cars on it, there are these big ships called transport vessels that can carry yachts. These ships are really sturdy and safe, so the yachts don't get damaged while they're being transported.
To get the yacht onto the transport ship, they use a special machine called a crane. It's kind of like a giant claw that attaches to the boat and lifts it up really high in the air, then moves it slowly over to the transport ship. The yacht is carefully placed onto the transport ship and fastened down so it doesn't move around.
Once the yacht is on the transport ship, it's sailed to the destination where the rich person wants to vacation. When they get there, the yacht is carefully lifted off the transport ship and placed back in the water, so the rich person can use it just like normal.
So, it's kind of like sending your favorite toy to your grandma's house, but instead of packing it in a box, you send it on a big ship!
