The French brig sloop La Jalouse was launched in Dunkirk in 1794. She is a typical large French brig used for convoy, raiding and escort duty. She was taken by the British vessel Vestal on 13th May 1797 and re-named Jalouse. She was then fitted out for duties in the Royal Navy. The only features that distinguished her as being of French origin were the 90° angle to the keel of the rudder post and the tops and crosstrees and trestletrees. After ten years in British service, she was broken up in 1807. Jalouse had a compliment of 121 officers and men. She carried 18 x 6 pounder guns, although the armament may well have been replaced by 18 x 32 pounder carronades sometime after her capture.

Her dimensions were as follows:

102' 10" long
85' 4" keel length
27' 9" wide
12' 11.5" draught
