ELI5: Explain Like I'm 5

420 (dinghy)

420 is a small boat that can fit two people at a time. It looks like a mini sailboat and is really fun to use in the water. The name "420" comes from its length, which is 4.20 meters long. People use 420s for lots of different things, like racing or just cruising around on the water. When you're in a 420, you use a sail to catch the wind and move across the water. It's like a big kite that helps push you forward. But be careful, you need to know what you're doing and wear a life jacket to stay safe!
