[4] The HBC sailed Sea Horse for ten years, as she carried trade between the company's outposts in the Bay and London.

[2][7] Sea Horse next appeared in Lloyd's List's ship arrival and departure (SAD) data on 24 July 1794 with Patterson, master, sailing on a voyage from Gravesend to Leghorn.

In October 1795 a French squadron captured Sea Horse, Patterson, master, as well as a number of other British merchantmen, and took them into Cadiz.

[9] The advertisement for the sale of the vessel and her cargo described her as "formerly the Ship Sea-horse, built in the River Thames, of near 300 tons".

[14] Her first role was a transport for Admiral Home Riggs Popham's expedition to capture the Cape Colony.

Daly was present at its surrender by the Dutch to the British, and was charged with reporting this to the Admiralty in London, for which he was rewarded by promotion to Commander.

After Napoleon's escape from Elba, Sea Horse again served the Transport Board from 22 March 1815 to 29 September.

These ships were travelling together carrying soldiers and their families to Cork at the end of the Napoleonic War when all three wrecked in Tramore Bay.
