From July 1803 to 1809 "Triton" was commanded by Commander William Cashman; she was fitted as a receiving ship at Woolwich in September 1803, likely because of the wear on the ship caused by her experimental design. By this time the ship's armament had been decreased to twelve nine-pounders and ten twenty four-pound carronades only. In 1807 "Triton" was the guard ship at Waterford; at the beginning of the Anglo-Russian War on 2 September she successfully detained the ships "Norway Lion" and "Karen Helena". Her final service was as receiving ship at Plymouth from August 1810.
