The ship that became Mary Ann was built in 1772 in France and the British captured her c. 1778. Her name may have been Ariadne until 1786 when she started to engage in whaling. Next, as Mary Ann, she made one voyage transporting convicts to New South Wales from England. In 1794 the French captured her, but by 1797 she was back in her owners' hands. She then made a slave trading voyage. Next, she became a West Indiaman, trading between London or Liverpool to Demerara. It was on one of those voyages in November 1801 that a French privateer captured her.
Charming Kitty was a ship captured from the Spanish. She first appears in the Protection Lists for whalers in 1799. She conducted four whaling voyages between 1799 and 1808 before becoming a West Indiaman, trading with the Caribbean. She was wrecked in October 1813.
Butterworth was launched in 1778 in France as the highly successful 32-gun privateer Américaine, of Granville. The British Royal Navy captured her early in 1781. She first appeared in a commercial role in 1784 as America, and was renamed in 1785 as Butterworth. She served primarily as a whaler in the Greenland whale fisheries. New owners purchased her in 1789. She underwent a great repair in 1791 that increased her size by almost 20%. She is most famous for her role in the "Butterworth Squadron", which took her and two ship's tenders on an exploration, sealing, otter fur, and whaling voyage to Alaska and the Pacific Coast of North America. She and her consorts are widely credited with being the first European vessels to enter, in 1794, what is now Honolulu harbour. After her return to England in 1795, Butterworth went on three more whaling voyages to the South Pacific, then Africa, and then the South Pacific again. In 1802 she was outward bound on her fourth of these voyage, this to the South Pacific, when she was lost.
Britannia was built in South Carolina in 1772. Prior to 1798, Britannia sailed between London and South Carolina, or simply served as a transport. In 1798 she changed ownership and began a sequence of whaling voyages. Between 1798 and 1807 she made a number of whaling voyages to the South Seas whale fishery, and the coast of South Africa. On one of those voyages a French privateer captured her, but Britannia was recaptured almost immediately. Between 1808 and 1816, the last year in which she is listed, she returned to operating as a London-based transport.
DuBuc was a vessel captured in 1797 and sold that year for mercantile use. She initially became a West Indiaman, but then the whaling company Mather & Co. purchased her. She made four voyages for them, being condemned at Hobart in October 1808.
Backhouse was launched at Hull in 1799 as a West Indiaman. Mather & Co. purchased her in 1800 and then employed her on two whaling voyages to the Southern Whale Fishery. They sold her in 1805 and her new owner sailed her to the West Indies. In September 1806, as she was homeward-bound, her crew burned her as she was too leaky to continue.
Rockingham was launched in America in 1767 as Almsbury. By 1768 Samuel Enderby & Sons were her owners and her name was Rockingham. From 1775 Enderbys were using her as a whaler, and she made eight whaling voyages for them under that name. In 1782 Enderbys renamed her Swift, and as Swift she then performed ten whaling voyages on the Brazil Banks and off Africa until through 1793. She was still listed in Lloyd's Register as whaling until 1795.
Neptune was launched in the Thirteen Colonies in 1778. She entered Lloyd's Register as Neptune in 1786. She then sailed as general merchantman. In the late 1790s she was a whaler in the British southern whale fishery. She was last listed in 1803, though the data is stale and she was last surveyed in 1797.
Lord Hawkesbury was launched in the United States in 1781, probably under another name. She entered Lloyd's Register in 1787. She made six voyages as a whaler. On her second whaling voyage she "the first parcel of ambergris 'by any English whaler'". She was lost on the seventh after a squadron of French naval vessels had captured her. One of her original, British crew succeeded in regaining sufficient control from her prize crew to enable him to run her aground, wrecking her.
Fonthill was a ship built in France in 1781 and was probably taken in prize in 1782. Fonthill sailed as a West Indiaman between 1783 and 1791, then became a whaler southern whale fishery and made four whaling voyages between 1791 and 1799. On her third voyage she took back from Cape Town a Dutch captain whose vessel had been captured bringing in arms and ammunition from Batavia to stir up unrest against the British at the Cape. After refitting, in 1800, Fonthill became a whaler in the northern whale fishery. Fonthill was last listed, with stale data, in 1810, but whose last reported whaling voyage took place in 1806.
Chesterfield was built in America in 1781, but it is not clear where and under what name. She arrived in England in 1791. Between 1792 and 1798 Chesterfield made three voyages to the southern whale fishery. She then traded with the Mediterranean until a Spanish privateer captured her in 1805.
Venus was launched at Deptford in 1788 and made 15 voyages as a whaler in the British southern whale fishery. Of 812 whalers in the British southern Whale Fishery database for which there was data, she had the fifth highest number of whaling voyages. She was last listed in 1823.
Barbara was launched in Philadelphia in 1771 and came to England circa 1787. She initially sailed as a West Indiaman, but then between 1788 and 1800 made five complete voyages as a whaler. The Spanish captured her late in 1800 in the Pacific during her sixth whaling voyage.
Morse was launched in 1747 for the British Royal Navy, but under another name. After 1775 she was John and Alice (1775), Potomack (1776–1779), Betsy (1780-1781), and then in 1782 Resolution. In 1784 S. Mellish purchased her and she became the whaler Morse. She initially engaged in whale hunting in the British northern whale fishery. Then from 1787 she made numerous voyages as a whaler primarily in the southern whale fishery, but with some returns to the northern fishery. There is no further mention of her in Lloyd's List Ship arrival and departure (SAD) data after August 1802.
Spy was built in France in 1780, almost surely under another name, and taken in prize. The British East India Company (EIC) purchased her in 1781 and used her for almost two years as a fast packet vessel and cruiser based in St Helena. It then sold her and she became a London-based slave ship, making two voyages carrying slaves from West Africa to the West Indies. She then became a whaler, making seven whaling voyages between 1786 and 1795. She was probably wrecked in August 1795 on a voyage as a government transport.
Nimble was built in Folkestone in 1781, possibly under another name. In 1786 Nimble was almost rebuilt and lengthened. Between 1786 and 1798 she made nine voyages as a whaler in the British Southern Whale Fishery. Between 1799 and 1804 she made four voyages from Liverpool as a slave ship. On her first voyage as a slave ship she detained a neutral vessel, an action that resulted in a court case. On her second slave-trading voyage a French privateer captured her, but the Royal Navy recaptured her. She was sold in 1804 at St Thomas after she had delivered her slaves.
Quaker was built in America in 1774, possibly under another name, and was taken in prize in 1780. She appears in British records from 1781. Between 1781 and 1783 she sailed as a privateer and captured several ships, American, Spanish, and French. She then became a whaler, making four voyages to the British southern whale fishery. Thereafter she became a West Indiaman. The French captured her in 1795.
Sappho was launched at Shields in 1785. She spent most of her career trading with the Baltic, though she made some voyages elsewhere, and in particular, between 1788 and 1799 she made a voyage to the Falkland Islands as a whaler. She was last listed in 1798, having perhaps been captured in late 1797.
Sparrow was built in Bombay in 1777, possibly under another name. Between 1789 and 1798 Sparrow made several voyages as a whaler in the British southern whale fishery. In 1803 she was captured and recaptured. The French Navy captured and burnt her in 1806.
Chaser first appeared under that name in British records in 1786. She had been launched in 1771 at Philadelphia under another name, probably Lord North. Lord North became Cotton Planter, and then Planter, before she became Chaser. Between 1786 and 1790 Chaser made four voyages as a whaler in the British southern whale fishery. She then became a merchantman. In 1794 a privateer captured her but the Spanish recaptured her. She became a Liverpool-based slaver. In 1796 she was condemned in West Africa on her first voyage in the triangular trade before she could embark any enslaved people.
