Watercraft are like cars that you can drive on the water, like boats and ships. Instead of wheels, watercraft have things called "hulls" that let them float on the water.
Some watercraft are small and have oars or a motor to move, like canoes or speedboats. Others are really big and can carry hundreds or even thousands of people, and they have massive engines and propellers to power through the water.
Watercraft are important for many reasons. People use them for transportation to go places, like across a lake or river. Fishermen use them to catch fish. Some people even use them for fun, like jet skiing or wakeboarding.
But it's important to be safe when using watercraft. Always wear a life jacket, follow the rules of the waterway, and don't drink alcohol while operating a watercraft.
