Ship

A ship is a big boat. Boats let you travel on a body of water. Ships do the same thing, except they're big so they can carry more than a few people. In fact, they can carry lots of people, and even a bunch of goods all in one go.

Some people despise ships (even calling them a work of the devil), but ships are actually a godsent, because it allows to carry multiple people at once over a body of water.

While travel through ship is still an option, this is usurped by the airplane, a craft that flies through the air at high speeds, making it not only faster but also lets you travel to more locations. The airplane also usurps the train, which is limited on rails, and buses, which are limited to roads.
