The vessel, constructed at a cost of £7,803, was launched on 11 May 1820 from the Woolwich Dockyard on the River Thames. Later reports say the ship took part in celebrations of the coronation of King George IV of the United Kingdom, passing through the old London Bridge, and was the first rigged man-of-war afloat upriver of the bridge.

Her poor condition on her return meant that the Admiralty replaced her for the second voyage in 1831 with another Cherokee-class brig, Beagle, which subsequently became famous because of the association with Charles Darwin. Chanticleer then spent 15 years as a customs watch ship at Burnham-on-Crouch and was broken up in 1871.
