ELI5: Explain Like I'm 5

SkySails

Skysails are like big kites that attach to the top of boats. They look like parachutes and have a big tether that helps them fly. When they catch the wind, they make the boat go faster, so they can help save fuel and money. It also helps the boat go faster so it can get to its destination faster. Skysails are a great way to help boats be better for the environment too.
