Bermuda rig

Imagine you're playing with toy boats in a bathtub. You've seen big boats with one tall pole sticking up in the middle, holding a triangular sail. But the Bermuda rig is different - it has two poles sticking up, and the sail is shaped more like a triangle with a pointy top and a curved bottom.

The two poles are called the mast and the boom. The mast is tall and skinny, and it holds up the sail. The boom is shorter and wider, and it sticks out to the side of the boat. The sail is held tight between the mast and the boom, and it catches the wind to make the boat go.

Because the sail is curved at the bottom, it's called a "foresail" or a "jib." This helps the boat to catch more wind even when it's not pointed straight into the breeze. The pointy top of the sail is called the "head," and it helps air flow smoothly over the sail's surface, like a wing on an airplane.

Overall, the Bermuda rig is a popular choice for sailboats because it's efficient and easy to handle. So grab your toy boats and try to make your own Bermuda rig sail!
