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.
Ob River
Tyumen had its first steamboat in 1836, and steamboats have navigated the middle reaches of the Ob since 1845. The first steamboat on the Ob, Nikita Myasnikov's "Osnova", was launched in 1844; the early starts were difficult, and it was not until 1857 that steamboat shipping started developing in the Ob system in a serious way. Steamboats started operating on the Yenisei in 1863, on the Lena and Amur in the 1870s. 
In 1916 there were 49 steamers on the Ob; 10 on the Yenisei.
