HMS Rover was a Royal Navy Cruizer-class brig-sloop laid down in 1804 but not launched until 1808. She served in the North Sea, off the north coast of Spain, in the Channel, and on the North American station. She captured two letters-of-marque and numerous merchant vessels before being laid-up in 1815. She then sat unused until she was sold in 1828. She became a whaler that made four voyages to the British southern whale fishery between 1830 and 1848. She was last listed in 1848.

Admiral Francis Erskine Loch was a senior commander in the Royal Navy during the early 19th century. He served as naval aide-de-camp to Queen Victoria.
