What was the name of the first paddle steamer to cross the Atlantic?

The SS Savannah, built in 1818. was the first steamship to cross the Atlantic, in early summer of the following year, 1819. Savannah was a hybrid, part sail and part steam-powered side-wheeler, and did not cross entirely under steam. The first two to cross entirely under steam were the Sirius and the Great Western, in 1838, who ran a competitive race from England to New York. The Sirius arrived only a few hours ahead of the Great Western. The two are credited with inaugurating regular transatlantic steam service.

How long to sail across the Atlantic Ocean in the eighteenth century?

In 1898, the Komonder Sved Foyu made the passage from New York to London in 20 days. ------------------------ 1898 was at the end of the 19th century (not the 18th as asked in the question), a time when trans-Atlantic ships were frequently steamships or combination of steam and sail. The first steamship crossing of the Atlantic was in 1819 and took just under a month. (SS Savanah). Steam or steam/sail were significantly faster and more reliable than the sailing ships of the 18th century had been. Trans-atlantic crossings in the late 1890s in a steamer usually took 7 to 10 days in the more recent passenger ships. In the 18th century (1700-1799) all trans-Atlantic crossings were by sail only. I have read that 2 to 4 months was average - varying by season and by direction (sailing east was faster than sailing west). ----------------------- Svend Foyu was a Norwegian shipping magnate who made his fortune in whaling - specifically due to his use of harpoon cannons with exploding harpoons. I am unable to discover whether the "Komonder Sved Foyu" mentioned in the original response to this question was connected with Svend Foyu nor whether it was a sailing boat, sail/steamer, or steamer only.
