In 1736, Jonathan Hulls

was granted a patent in England for a Newcomen engine-powered steamboat (using a pulley instead of a beam, and a pawl and ratchet to obtain rotary motion). However it was not until 1774 that Claude de Jouffroy

(and his colleagues) built a working 13-metre (42ft 8 in) steamboat with rotating paddles, called the Palmipède.

The link below shows a picture of a replica of this boat.
