Comet was launched in 1791 at Rotherhithe. At the outbreak of war with France, she briefly became a privateer before the British East India Company (EIC) chartered her for one voyage to bring back sugar, saltpeter, and other goods from Bengal. Between 1812 and 1821 she made three voyages as a whaler in the British Southern Whale Fishery. Then between 1823 and 1840 she became a whaler based in Hull, whaling in the British Northern Whale Fishery. She returned to trade in 1841 and was lost on 1 December 1843 homeward bound from Quebec.
