HMS Harpy was a Royal Navy Diligence-class brig-sloop, launched in 1796 and sold in 1817. She was the longest lived vessel of her class, and the most widely travelled. She served in both the battle of Copenhagen and the British invasion of Java, took part in several actions, one of which won for her crew a clasp to the Naval General Service Medal, and captured numerous privateers. The Navy sold her in 1817.

HMS Monkey was launched in 1801 at Rochester. She served in the Channel, North Sea, and the Baltic, and was wrecked in December 1810.
