1837 The Transatlantic Steamship Co bought the Great Liverpool from Sir John Tobin.
After three years, its Directors were satisfied that the cost of equipping and maintaining a transatlantic connection by steam vessels, without the aid of a Government contract, was unprofitable
The opportunity to employ their vessels more profitably arose in the form a proposal from the proprietors of the Peninsular Steam Packet Co to join that enterprise.
The company's two vessels, the Great Liverpool and the Oriental, were transferred to the Peninsular Company.
