What is the difference between a 15th century caravel and a ship built in the 20th century?

Oh, dude, like, a 15th century caravel is, like, super old school, you know? It's all about those wooden sails and, like, exploring the high seas without GPS or Wi-Fi. A ship from the 20th century? Well, that's like, way more modern, with, like, engines and stuff. So, yeah, they're pretty different, but they both float, so that's cool.
