She was commissioned in October 1805 under Commander John Simpson. On 3 January 1806 she recaptured the ships Argo and Adventure, and shared in the recapture of the Good Intent. Starr was off Villa de Conde, Portugal, when she intercepted the vessels, which had been taken from a convoy that Mercury had been escorting from Newfoundland to Portugal, and both of which had been carrying cargoes of fish. Starr sighted Good Intent and signaled Mercury, which recaptured her too. On 5 February, Curieux captured the Baltidore, which was the privateer that had captured Good Intent.
