The Southwell is shown at sea, with the inscription TRADING ON YE COAST OF AFRICA. Like A View of Ye Jason Privateer this drawing shows the three stages of the slave trade. Pocock depicts the ship at sail in the central cartouche that forms a decorative border at the bottom of the composition. On one side of the cartouche is a drawing of enslaved Africans being led onto the boats that will carry them to the ships. On the other, goods are handed over to the traders in return. The Southwell was employed as a slave ship by 1746, the year that 150 enslaved Africans died on the voyage from Africa to Antigua.
