Captain James Wilson volunteered his services and the society was able to afford to purchase Duff.
Lloyd's Register for 1796 shows that Wilson replaced Gordon as master of Duff, and Cox & Co. replaced J. Carbine as owner. Also, her trade changed to London-Port Jackson.
By 1797, her trade was London-South Seas.
The London Missionary Society has 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.
Captain Wilson and Duff had left The Downs on August 13, 1796, and by November 12 she was at Rio de Janeiro.
On March 6, 1797 (celebrated as Missionary Day in French Polynesia) she reaches Matavai (Mahina), where fourteen missionaries and their families disembark.
Duff will next deliver nine volunteers to Tongatapu on March 26.
One leaves immediately, and over time the locals will kill three.
