She then sailed for a few years as a West Indiaman before completing four voyages as a slave ship in the triangular trade in enslaved people.

[b] Royal Edward acquired her captives at Bonny Island, and arrived at Kingston, Jamaica on 14 July 1800, with 396.

Royal Edward left St Croix on 2 July, and arrived back at Liverpool on 4 August.

This led the government in the Danish West Indies to encourage the importation of captives prior to the ban taking effect.

Records for the period 1796 to 1799 show that 24 British enslaving ships, most of them from Liverpool, arrived at St Croix and imported 6,781 captives.

[13] The Slave Trade Act 1807 forbade British vessels from engaging in enslaving; because Royal Edward had left the United Kingdom well before the 1 May 1807 deadline, her fourth voyage remained legal.

[2] The 1810 volume of Lloyd's Register showed Royal Edward with Clint, master, Mullion, owner, and trade London–Havana.

[14] Lloyd's Register for 1813 shows Royal Edward's master as J. Boyd, her owner as I. Cooper, and her trade London–St Ubes.

Lloyd's Register for 1816 showed Royal Edward with E. Burford, master, I. Cooper, owner, and trade London–Île de France.

[3] Royal Edward, Balston, master, arrived at Calcutta from Île de France in late August 1815.
