Steamboat services started on the Thames in around 1815 and for nearly 25 years were the main use of steam to carry passengers before the emergence of railways in the south of England. During this time at least 80 steamers are recorded in the Thames and the Steamboat Act of 1819 became the first statute to regulate the safety of the new technology for the public. Wooden boats driven by paddle-wheels, they managed during this time to establish themselves as faster and more reliable than the earlier use of sailing and rowing boats for passenger transport within the Thames estuary.
