On 14 January 1788 Olive Branch, Crow, master, sailed from the Downs, bound for the Brazils.

However, there is no evidence in the Lloyd's List ship arrival and departure (SAD) data of any such voyage.

The 1790 volume showed Olive Branch's master changing to Clark, and her trade to London–Gibraltar.

On 4 August 1789, the snow Olive Branch, of "One Hundred Tons or thereabouts", lying at Mr. Oliver's dock at Warping Will was offered for sale by auction at Lloyd's Coffee House, pursuant to a decree by the High Court of Admiralty.

[1] It is possible that the Admiralty purchased her for use as the fire ship HMS Olive Branch, of 103 tons (bm).
