Écluse was a gabarre launched at le Havre in 1764 for the French Navy.

The navy lent her out to private parties who made one voyage as a slave ship (1770–1771), in the triangular trade in enslaved persons.

She sailed from Africa on 1 June 1771 and arrived at Port-au-Prince with 188 slaves, 73 men, 65 women, 22 boys and 28 girls, on 13 July.

She lost five men on her voyage: one man drowned on the way to Africa, three died while she was on the coast, one of whom was killed by locals while embarking slaves, and one at Saint-Domingue.
