From 1780 to 1786 she was a British vessel that was a transport and traded generally. In 1786–1787 she made one voyage for the British East India Company (EIC). From 1788 she traded between London and Ostend, and was last listed in 1793 with unchanged data. In 1788 she had sailed to the East Indies, perhaps with new owners from Ostend, and may have remained in the East Indies. was launched in 1774 in Virginia, possibly under another name.

She underwent grounding in 1795 and in 1796 her owners had her repaired, lengthened, and converted from a brig to a ship. A French privateer captured her in August 1797 after a single-ship action. In a process that is currently obscure, Ranger returned to British ownership circa 1799. She then became a West Indiaman. From 1803 on she became a Liverpool-based slave ship in the triangular trade in enslaved people. She made one complete slave trading voyage. Then French privateers captured her after she had embarked slaves in West Africa but before she could deliver them to the West Indies.
