Steamboat
Similar boats were made in 1785 by John Fitch in Philadelphia and William Symington in Dumfries, Scotland. Fitch successfully trialled his boat in 1787, and in 1788, he began operating a regular commercial service along the Delaware River between Philadelphia and Burlington, New Jersey, carrying as many as 30 passengers. This boat could typically make and travelled more than during its short length of service. The Fitch steamboat was not a commercial success, as this travel route was adequately covered by relatively good wagon roads. The following year, a second boat made excursions, and in 1790, a third boat ran a series of trials on the Delaware River before patent disputes dissuaded Fitch from continuing.
Electric boat
While a significant majority of water vessels are powered by diesel engines, with sail power and gasoline engines also popular, boats powered by electricity have been used for over 120 years. Electric boats were very popular from the 1880s until the 1920s, when the internal combustion engine took dominance. Since the energy crises of the 1970s, interest in this quiet and potentially renewable marine energy source has been increasing steadily again, especially as solar cells became available, for the first time making possible motorboats with an infinite range like sailboats. The first practical solar boat was probably constructed in 1975 in England. The first electric sailboat which made a round-the-world tour, including the through the Panama Canal, with only green technologies is EcoSailingProject.
