HMS Mermaid was a 32-gun Active-class fifth-rate frigate of the Royal Navy, launched in 1784 and broken up in 1815. During the French Revolutionary Wars she served in the West Indies, the Channel, and the Mediterranean. During the Napoleonic Wars she first served in the Americas, but from early 1811 on, she was armed en flute and served as a troopship until she was broken up.

HMS Zebra was a 16-gun Zebra-class sloop of the Royal Navy, launched on 31 August 1780 at Gravesend. She was the second ship to bear the name. After twenty years of service, including involvement in the West Indies campaigns during the French Revolutionary Wars, she was converted into a bomb vessel in 1798. In this capacity she took part in attacks on French ports, and was present at both battles of Copenhagen. The Navy sold her in 1812.
