Watercraft, also known as water vessels or waterborne vessels, are vehicles used in and on water, including boats, ships, hovercraft, and submarines. Watercraft usually have a propulsive capability (whether by sail, oar, paddle, or engine) and hence are distinct from a simple device that merely floats, such as a log raft.
