SS President

SS President was a British passenger liner that was the largest ship in the world when she was commissioned in 1840, and the first steamship to founder on the transatlantic run when she was lost at sea with all 136 on board in March 1841. She was the largest passenger ship in the world from 1840 to 1841. The ship's owner, the British and American Steam Navigation Company, collapsed as a result of the disappearance.

President was the second liner owned by British and American and was noted for her luxurious interiors. Designed by Macgregor Laird and built by Curling and Young of London, she was fitted for 154 passengers. President was over 25% larger than the British Queen, the previous holder of the size record, and over twice the size of Cunard's Britannia Class, the first three of which were also commissioned in 1840. This was accomplished by adding a third deck to the design of the British Queen. As a result, President was top-heavy and rolled excessively. She was also underpowered and had the slowest passage times of any transatlantic steamer up to that point. To avoid litigation, changes were made to her paddle wheels after her second round trip that further complicated her lack of power, especially in rough weather.

On 11 March 1841, President cleared New York bound for Liverpool on her third eastbound voyage. She was overloaded with cargo to compensate for her roll. President was last seen the next day struggling in a gale. Her disappearance was major news for several months and even Queen Victoria followed the story.
