Sir William Douglas

Sir William Douglas was a slave ship in the triangular trade in enslaved people, acquired by British interests in 1801. She made one complete voyage transporting enslaved people and was captured in 1803 after having delivered captives on her second voyage. Career There is some ambiguity about Sir William Douglass origins. Lloyd's Register (LR) reported that she was launched in 1800 in San Sebastian. The Register of Shipping (RS) gave her origin as a Spanish prize taken in 1800. The Trans-Atlantic Slave Trade database reports that she was built in 1799 at Ramsgate. Although the Trans-Atlantic Slave Trade database has no data on the number of captives that Sir William Douglas carried on her two voyages, she does appear, as ship and brig, on a list of vessels that brought captives to the United States during the period 1790–1810. 1st voyage transporting enslaved people (1801–1802): Captain William Hannay acquired a letter of marque on 22 August 1801. He sailed from London on 5 September, bound for Africa. In 1801, 147 vessels sailed from British ports on voyages to transport enslaved people; 23 of these vessels sailed from London.
