With the conclusion of the Dover trials, Archimedes was placed at the disposal of Captain Chappell for a circumnavigation of Britain, which took place in July 1840. This voyage presented an opportunity to not only conduct further tests, but also to allow inspection of the technology by shipowners, engineers and scientists in ports throughout the country. Archimedes completed the 2006-mile voyage at an average speed in excess of 7 mph, and a maximum speed under ideal conditions of 10.9 mph.[23]
