French ship Écluse (1764)
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 then returned to naval service. In May 1779 she participated in the unsuccessful invasion of Jersey; a British naval squadron succeeded in capturing or destroying much of the French squadron, and burnt Écluse. She was recovered and returned to service. In 1782, after the end of the war, the navy lent her out to serve as a merchantman. She was decommissioned in 1788.
