SS Sirius crosses the Atlantic from Cork to New York

Background. Prior to the 19th century, transatlantic crossings were undertaken in sailing ships, which were time-consuming and perilous. The advent of steamships made these crossings faster, safer, and more reliable. The SS Sirius, a wooden-hulled sidewheel steamship built in 1836, was originally designed for the Cork-London service. In 1838, it was chartered for transatlantic voyages, competing with the Great Western, which was recognized as the first purpose-built transatlantic steamship.

Competition with Great Western. The SS Sirius was chartered by the British and American Steam Navigation Company for two voyages. It competed directly with the Great Western, which was ready for its first voyage by April 1838. The Sirius arrived in New York a day ahead of the Great Western, securing its place in history as the first holder of the Blue Riband, despite the term not being used at the time.

Legacy and Recognition. The Blue Riband has been tracked since 1838 for the fastest average speed of a steamship in regular service across the Atlantic. The Sirius's 18-day crossing from Cork to New York City is recorded in historical timelines. Although the Sirius was too small for the route, completing only one additional round trip, its achievement remains significant in the history of transatlantic steam navigation.
