First Arrangement of PS COMET 

In her original configuration PS COMET, the first commercial steam ship in Europe, had 4 paddle wheels, two on either side. Each wheel had four non-feathering floats. Presumably she could be heard from far away. 

That arrangement did not provide satisfactory and she was altered to a two wheel configuration. 

The drawing shows the original four wheel configuration. 

Comets First Engine 1811-1812 

 John Robertson was an early steam engine builder based in Neilson, Renfrewshire. He was one of the first engineers to design steam systems for the heating if mills and factories.

In 1808 Robertson supplied a small steam engine to Henry Bell, the new proprietor of the `baths Hotel in Helensburgh to pump sea water. In 1811 Robertson agreed to build an engine for Bell’s new steamship, PS COMET Then under construction in John Woods shipyard at Port Glasgow. The agreed price was £165, which did not include the price of the boiler. The latter was supplied by David Napier..

A second more powerful engine was fitted to Comet after a few years. Her original machinery was acquired by Bailie MacLellan  to provide  power at his coach works in Miller Street, Glasgow. A few years later Comets first engine went to a brewery company in Greenock. Thereafter the engine was purchased by Robert Napier and gifted to the South Kensington Museum in 1862, it is still there.
