Amphion turned out to be one of Chapman's few failures as a ship designer. She suffered from poor seakeeping ability and was also too heavy to row. On her maiden voyage from Karlskrona to Stockholm, poor weather conditions left Amphion shipwrecked in the archipelago of Stockholm, and Gustav III was required to come ashore at Dalaro. Thereafter, she was used mostly for trips out on Lake Mälaren, though also she was used as the king's personal command ship during The Russo-Swedish war of 1788–1790. She later served as a barracks ship into the 19th Century.
In 1884, Amphion was broken up for firewood. Amphions figurehead and stern castle with the royal command room were spared, and can be seen at the Maritime Museum in Stockholm. The preserved parts underwent preservation and restoration, performed by conservation studio Ateljé Catellani, between 2003 and 2006.
The current stern was added in 1791 after the ship was damaged at the end of the Russian War. The former stern lacked the royal cypher, and its four windows gates were of a simpler design.
