Experiment was launched on the River Thames in 1789. She made seven voyages for Calvert & Co. as a slave ship in the triangular trade in enslaved people, carrying captives from the Gold Coast to Jamaica. A French squadron captured her in 1795.
Countess de Galvaez was launched in 1780 in the Americas, probably under another name, and lengthened and rebuilt in 1785, when she assumed British registry. She then traded with Mobile, New Orleans, Pensacola, or more simply, the "Mississippi". From 1791 on she made one voyage as a whaler and one as a slave ship in the triangular trade in enslaved people. There is some confusion about her ownership in the period 1791–1794. She was lost in 1794 on her return to England from her slave-trading voyage.
Robust was built in France in 1779. The British captured her in 1781 and she was registered at Liverpool in 1783. She first entered Lloyd's Register in 1789 as whaler in the northern whale fishery. Then in December 1788 she left on the first of three voyages as a slave ship in the triangular trade in enslaved people. On her third voyage as a slave ship Robust captured a French slave ship and recaptured two British slave ships that a French privateer had captured earlier. After her third voyage as a slaver owners shifted her registry to Bristol and she then made two voyages to the southern whale fishery. She returned from the second voyage in 1797 and is last listed in 1798.
Sally was launched in 1782 at Liverpool as a West Indiaman. She made one voyage as a whaler and one as an East Indiaman sailing to Bengal under charter to the British East India Company (EIC). After a storm damaged her in 1805 as she was on her way in 1805 from Liverpool to Africa as a slave ship she had to put into Barbados where she was condemned.
Duke of Buccleugh, was launched at Yarmouth in 1783. In 1789 she became a slave ship in the triangular trade in enslaved people. She made five complete enslaving voyages. On her fifth she had to repel an attack by a French privateer in a single ship action. A French privateer captured her in September 1797 after she had delivered her captives on her sixth voyage.
Caroline was a ship launched in France in 1792, possibly under another name. She was taken in prize in 1794 and sailed first as a West Indiaman, then as a whaler in the British southern whale fishery, and finally as a slave ship in the triangular trade in enslaved people. She was lost in 1801, after she had delivered her captives to Kingston, Jamaica on her second voyage from Africa.
Several ships have been named John:
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 in the triangular trade carrying enslaved people 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.
Harriot was launched in Spain in 1794, almost surely under another name, and taken in prize in 1797. She made two voyages as a London-based slave ship in the triangular trade in enslaved people. Under new ownership, she then made three voyages as a whaler in the British southern whale fishery. A privateer captured her as she was returning from her third whale-hunting voyage but the British Royal Navy recaptured her. After her recapture she became a merchantman. The Spanish seized her in the Pacific; she was condemned at Lima, Peru in March-April 1809, as a smuggler.
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 in the triangular trade in enslaved people. On her first voyage as to gather captives she detained a neutral vessel, an action that resulted in a court case. On her second voyage to gather captives, a French privateer captured her, but the Royal Navy recaptured her. She was wrecked in 1804 or so after she had delivered her captives to St Thomas.
Mentor was launched in New England in 1781. From 1784 she sailed from Great Britain, trading between London and New York or Quebec. From 1789 she made three complete voyages as a whaler in the British Southern Whale Fishery. The French Navy captured her in early 1795 as she was returning from her fourth whaling voyage.
Mentor was the former HMS Wasp. The British Royal Navy sold Wasp in 1781 and she became the mercantile Polly, which traded with Africa. In 1784 Polly became the slave ship Mentor. Mentor made eight full voyages in the triangular trade in enslaved people. She carried captives from The Gambia to the West Indies. French privateers captured her in late 1795 as she was on her way from West Africa to the West Indies on her ninth voyage.
John was registered in Britain in 1790. She reportedly had been launched in the United States, but where and when is obscure. Between 1791 and 1794 she made four voyages as a slave ship in the triangular trade in enslaved people. On her first three voyages at least, the mortality rate among the slaves during the Middle Passage was so low that John's master and surgeon qualified for a bonus payment. In 1795 new owners sailed her as a whaler in the British Southern Whale Fishery. She was last listed in 1797.
Echo was launched in 1791 in Liverpool as a slave ship. She made two complete voyages from Liverpool in the Atlantic triangular slave trade. On her third voyage a French privateer captured her, but a British letter of marque recaptured her. She did not return to enslaving and was last listed in 1796.
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.
HMS Spy was a Bonetta-class sloop launched at Rotherhithe in 1756 for the Royal Navy. The Navy sold her in 1773. From 1776, or perhaps earlier she was a transport. Then from 1780 to 1783, as Mars, she was first a privateer and then a slave ship, engaged in the triangular trade in enslaved persons. Between 1783 and 1787 her name was Tartar, and she traded with the Mediterranean. From 1787, as Southampton, she was a whaler in the British southern whale fishery. She made at least four complete whaling voyages and was last listed in 1792.
Ranger was launched in Liverpool in 1789. She made four complete voyages as a slave ship in the triangular trade in enslaved people. A French privateer captured her in 1796 in a single ship action during her fifth voyage transporting enslaved people. She was recaptured, but thereafter disappears from online records.
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 Slave ship in the triangular trade in enslaved people. In 1796 she was condemned in West Africa on her first voyage in the triangular trade before she could embark any enslaved people.
Several ships have been named Lucy.
Brothers was launched in the Thirteen Colonies in 1772, probably under another name. From 1785 she became a Bristol-based slave ship. She made six complete voyages in the triangular trade, in all embarking 1880 enslaved people. The French captured her in December 1794 as she was on the first leg of her seventh such voyage and before she had embarked any captives. The main source for this article provided detail on crew turnover and death rates for her first three voyages. The first voyage had a particularly heavy mortality rate among the crew. The main source also provided data for her fourth, fifth, and sixth voyages for mortality rates on the Middle Passage among the enslaved people that she was carrying.
