Chart of the Gambier’s Islands, discovered by Capt: James Wilson. in the Ship Duff

In 1795 the just formed London Missionary Society decided to send missionaries to the South Pacific. Captain James Wilson volunteered his services and the society was able to afford to purchase Duff. The Society instructed Wilson to deliver a group of missionaries and their families (consisting of thirty men, six women, and three children) to their postings in Tahiti, Tonga, and the Marquesas Islands. Wilson in the and Duff left The Downs on 13 August 1796 and by 12 November she was at Rio de Janeiro. On 6 March 1797 she reached Matavai (Mahina), where 14 missionaries and their families disembarked. The Duff next delivered nine volunteers to Tongatapu on 26 March.  While sailing from Tongatapu to the Marquesas, Wilson became the first European to visit Pukarua, which he found uninhabited and named Searle Island. On 24 May Wilson sighted Mangareva in the Gambier Islands, which he named for James Gambier, then a Lord Commissioner of the Admiralty. The largest land feature on Mangareva is named Mount Duff. At Mangareva Duff stopped at Rikitea. Wilson was the first European to visit Temoe in the Gambiers, which he named “Crescent Island”. By 5 June Duff was at Resolution Bay, in the Marquesas, here the Duff landed William Pascoe Crook. On 6 July the Duff was at Matavai again and at Tahiti by 18 July. On 18 August she was back at Tonga. From there Wilson and Duff sailed for China, arriving on 13 December at Whampoa.

On this voyage Wilson charted the location of a number of islands. In the Caroline Islands he visited Satawal, Elato, and Lamotrek. In the Fiji Islands Wilson also charted Vanua Balavu, Fulaga, and Ogea Levu. In the Santa Cruz Islands, now part of Solomon Islands, Duff is remembered by the Duff Islands, charted on 25 September 1797. Wilson left China 5 Jan 1798 and reached Malacca on 16 January, the Cape of Good Hope on 17 March, and St Helena on 15 April. She was at Cork on 24 June, and arrived at Long Reach on 10 July.
