A ship is a large vessel that floats on water. Ships are generally distinguished from boats based on size and cargo or passenger capacity. In traditional terms, ships were considered to be vessels which had at least one continuous water-tight deck extending from bow to stern. However, some modern designs for ships, and boats, have made that particular definition less accurate. Ships may be found on lakes, seas, and rivers and they allow for a variety of activities, such as the transport of people or goods, fishing, entertainment, public safety, and warfare.
