This is a guide to different types of boats and ships from around the world. The primary difference between boats and ships is the size; the U.S. Naval Institute classifies boats as being small enough to be carried aboard a larger vessel, and a vessel capable of carrying a smaller one is a ship. Essentially, you can put a boat on a ship, but you can’t put a ship on a boat. This illustrated list of boat and ship types offers a sense of scale, presenting vessels from a vast range of history, culture, and purpose. From Navy ships to luxury yachts and fishing boats, it is truly marvelous how humans have constructed countless ways to navigate the seas and rivers throughout history.
