Royal Navy Admiral John Montague purchased American Tartar at Newfoundland on 9 October 1777 and renamed her HMS Hinchinbrook (or Hinchinbroke). At some point between 1777-1788 Hinchinbrook briefly came under the command of Lieutenant Isaac Schomberg. Commander John Brudenel (or Bradenel) had commissioned Hinchinbrook in September, but she was not formally registered and renamed until 25 February 1778. In October she was still on the Newfoundland Station. Her captain was Commander John Wainwright.Hinchinbrook arrived at Woolwich on 18 January 1780.
