She was launched on 1 July 1805 and saw active service under the British flag in Danish waters until 19 June 1808 when Dano-Norwegian forces sank her.

The Danes raised her and refitted her for service in the Dano-Norwegian Navy, which she served until the end of the English Wars in 1814.

She was active in 1807 in the North Sea and the Downs and received prize money for the following captures, either alone or in company with other British vessels.

[13] Lastly, Seagull's boats retrieved Dove,[14] which they found drifting and derelict on 29 August 1807 off the coast of France.

Within half an hour the Danish fire had badly damaged Seagull's rigging and dismounted five of her guns.

[16] Vice-Admiral Thomas Wells, on reading the battle report, expressed his strong opinion that such gallantry should be made public.

The Danes removed the crew of the Seagull, including the dead and wounded, and sent damage control parties aboard.

On 25 November 1808, this ship, now known simply in Danish records as The Seagull, successfully fought and captured a Swedish gunboat, Gripen.

[a] On 12 May 1810, The Seagull participated in a skirmish against the British 36-gun Tribune off Mandahl (present day Mandal, Norway).

[21] In the aftermath of the Battle of Lyngør, a British reconnaissance by the cutter HMS Nimble of Danish warships in the area reported the presence of The Seagull, of 16 guns and 100 men, lying at Christiansand - but concluded that the Danes could effect nothing of importance that summer (of 1812).

In late December Seagull, Lolland, and Samsøe sailed to Frederickshavn, Jutland to escort a convoy of vessels carrying much-needed grain to Norway.
