The Bermudas were modified versions of the Dasher-class sloop of 1797, and eventually consisted of six ships.

She was launched in 1805, and commissioned in October that year under the command of William Henry Byam, who transferred from Busy, which was then on the North America Station.

Bermuda was searching for a rich Portuguese ship when she hit a reef during the night.

She proved to be Concepcion, the vessel they were looking for Bermuda could not be freed from the reef, but Conception could be.

Byam and his crew captured the Portuguese ship, which they sailed on 26 April to New Providence, arriving on 4 May.
