Following these repairs, the British Admiralty arranged with Smith to undertake a new series of trials for Archimedes at Dover. Captain Edward Chappell, RN, was appointed by the Admiralty to oversee the trials and write a report. From April to May 1840, Archimedes was tested against the Navy's fastest Dover-Calais mail packets, the paddlewheelers Ariel, Beaver, Swallow and Widgeon.[22]
