sail
A sail is like a big, strong blanket that helps boats move across the water. Imagine when you blow on a piece of paper and it moves; that’s what the wind does to the sail. The wind pushes the sail, and the boat moves forward. It’s like when you run with a kite, and the wind makes it fly high in the sky.
Think of a sail as a giant wing for the boat. Just like birds use their wings to glide through the air, boats use sails to glide across the water. The sail catches the wind, and the boat can go fast or slow, depending on how much wind there is. It’s like magic, but it’s really just the wind doing all the work!
Another way to think about a sail is like a big hand that catches the wind. When you hold your hand out of a car window, you can feel the air push against it. The sail does the same thing, catching the wind and helping the boat move. The person steering the boat can move the sail to catch more or less wind, which helps the boat go where they want it to go.
