Steamboat is a term used for steam-driven vessels that sail on rivers. It also refers to the smaller vessels on lakes or in coastal waters of the sea. Steamship is used for large vessels such as those on the open sea. In 1787, John Fitch demonstrated the first workable steamboat in the United States. The first financially successful steamboat was Robert Fulton's Clermont. In 1807, it steamed the 150 miles (241 kilometers) up the Hudson from New York City to Albany in about 30 hours. Steamboats carried passengers on the great rivers before the development of railroads and other faster or more efficient means of transportation. Steamships are still used in many parts of the world.
