HMS Netley was originally the French privateer brig Déterminé, which the Royal Navy captured in 1807 and took into service.

Déterminé was a privateer brig commissioned in Bayonne in October 1803, that made her first cruise in October–November.

[2] Lloyd's List (LL) reported on 12 August 1806 that the French privateer Déterminée had captured Betsey, Selby, master, and sent her into Cayenne.

[3] Venus captured Déterminée, of Guadeloupe, on 18 January 1807 in the Atlantic Ocean 100 leagues (261 nmi; 300 mi; 483 km) east of Barbados after a chase of 16 hours.

Netley was under the command of Lieutenant Charles Burman when she sank on 10 July 1808 when a squall caused her to capsize off Barbados.
