Wingsail
Okay kiddo, have you ever seen a sailboat with a big, tall sail that catches the wind and helps it move through the water? Well, a wingsail is like that, but instead of a flat, fabric sail, it looks more like an airplane wing!
Just like how an airplane wing helps it fly, a wingsail helps a sailboat move faster by catching the wind and turning it into forward motion. But unlike a regular sailboat sail that can only catch the wind from one direction, a wingsail can be adjusted to catch the wind from all different angles, which can be really helpful if the wind is changing a lot.
Plus, wingsails are also great because they are made out of lightweight materials (kind of like a big kite) which means the sailboat can go even faster because it isn't weighed down by a heavy sail. So overall, a wingsail is a special kind of sail that helps sailboats move faster and more efficiently!
