HMS Tamar
Six ships and a naval station of the Royal Navy have been called HMS Tamar, after the River Tamar in South West England: HMS Tamar (1758) was a 16-gun sloop launched at Saltash in 1758 and stationed in Newfoundland from 1763. She was renamed HMS Pluto and became a fire-ship in 1777; the French captured her in 1780.
