British ships were then free to sail to India or the Indian Ocean under a license from the EIC.

On 8 July 1818, Princess Charlotte, Rennoldson, master, sailed for Ceylon under a license from the EIC.

The registers continued to carry Princess Charlotte with unchanged data until 1825–1826 when they showed her master having changed to Adamson and her trade as Dundee.

However, in 1820, Princess Charlotte had become a whaler sailing to the Northern Whale Fishery (Greenland and Davis Strait) from Dundee.

[6] During the 1820 whaling season, she took on board a good part of the oil from Brothers, which had been lost on 29 June at 74°N 25°W / 74°N 25°W / 74; -25.

[9] The data below came primarily from Coltish:[10] In 1831, a crew man was killed when he fell from Princess Charlotte's yards.

[16] When the ice crushed Princess Charlotte, Deuchars blew her hull open.
