# Iris (1783 ship)

Iris was launched at Liverpool as a slave ship in the triangular trade in enslaved people. In all she made eight voyages (1783-1800) transporting captives from West Africa to the Caribbean. She also made one voyage for the British East India Company (EIC) to Bengal and back (1795-1796). She was condemned in Jamaica in December 1800 as unseaworthy.

## Fate

Iris departed Kingston. After leaving port she encountered bad weather. On 12 December Lloyd's List reported that Iris, "Cannell", master, had put back into Kingston leaky. Iris was condemned there as unseaworthy.
In 1800, 34 British vessels in the triangular trade were lost, four of them on the homeward bound leg. Although Iris succumbed to a maritime mishap, during the period 1793 to 1807, war, rather than maritime hazards or resistance by the captives, was the greatest cause of vessel losses among British enslaving vessels.
