Later she became a Liverpool-based slave ship, making five voyages in the triangular trade in enslaved people.

Duguay Trouin was a 150-tonne French privateer sloop of 168 men and 18 to 20 guns, under Pierre-Denis Ducasso.

Duguay Trouin then had a number of successes:[6] In August, Commander Benjamin Hulke replaced Fish.

[1] On 12 February 1783, a three-ship flotilla, headed by the 28-gun corvette La Coquette under the command of the Marquis de Grasse-Briançon (nephew to Admiral Comte de Grasse), arrived at Grand Turk Island.

[7] The flotilla disembarked about 400 men, drawn from four regiments, under the command of M. de Coujolles, who took control of the island without resistance.

On 2 March the 44-gun HMS Resistance, under the command of Captain James King, while sailing in company with Duguay Trouin, discovered two of the French ships anchored in Turks Island passage.

[8] On being spotted the two ships cut their cables and stood to the southwest, upon which Resistance gave chase.

The rearmost ship, carrying 20 guns, sprang her main topmast; she surrendered after Resistance came up and fired a broadside.

Resistance then gave chase to the other, and after enduring fire from her stern chasers, came alongside; La Coquette promptly surrendered.

Christopher enteredLloyd's Register in 1786 (there is no issue for 1785), with J. Bolton owner, T. Scott, master, changing to J. Smith, and trade Liverpool-St Vincent.

[3] Under his command she captured three French vessels with produce from the West Indies, and a privateer from Martinique of 12 guns and 44 men.

[11] Smith brought into St Vincent a vessel from Guadeloupe that was carrying 150 hogsheads of sugar.

[3] Lloyd's Register for 1798 had J. Watson replacing "R. Rumsey" as master, and gave Christopher's trade as Liverpool-Demerara.

[23] Lloyd's Register continued to list her with Woodward, master, Bolton, owner, and trade Liverpool-Africa to 1809,[17] In 1806, 33 British slave ships were lost; eight were lost on the Middle Passage, i.e, after leaving Africa and before leaving for home.
