Pocock made finely detailed drawings of the ships which travelled to Africa and the West Indies that include images of the people who were enslaved as human cargo in the 'triangular' trade between West Africa, the West Indies and America, and the UK. A View of Ye Jason Privateer, around 1760, was made when he was three years into his seaman's apprenticeship when he was 20. The Jason, a French-built ship, is depicted at anchor, with what may be pilot and crew approaching in boats from the left and right.
