Fourteen men were required to make up the ship's complement. A new master was found in John Aken of the Hercules, a convict transport, and five seamen were engaged; but it was impossible to secure the services of nine others from amongst the free people. Flinders thereupon proposed to the Governor that he should ship nine convicts who could bring "respectable recommendations." King concurred, and the number required were permitted to join the Investigator, with the promise that they should receive conditional or absolute pardons on their return, "according to Captain Flinders' recommendation of them." Several of them were experienced seamen, and proved a great acquisition to the strength of the ship. Flinders also took with him his old friend Bongaree, "the worthy and brave fellow" who had accompanied him on the Norfolk voyage in 1799, and a native lad named Nambaree. It was determined, after consultation with King, to sail to the north of Australia and explore Torres Strait and the east side of the Gulf of Carpentaria, as well as to examine the north-east coast with more care than Cook had been able to give to it. The Lady Nelson, under Murray's direction, was to accompany the Investigator; if rivers were found, it was hoped that she would be able to penetrate the country by means of them. On the 21st July the provisioning of the ship was completed, the new boat was hoisted into her place, and the Investigator dropped down the harbour to make her course northward. The Lady Nelson proved more of a hindrance than a help to the work of exploration. She was painfully slow, and, to make matters worse, Murray, "not being much accustomed to make free with the land," hugged the coast, and kept the Investigator waiting for him at every appointed rendezvous. In August she bumped on a reef in Port Curtis and lost her sliding keel; in September she ran aground in Broad Sound and injured her main keel. Her capacity for beating to windward was never great, and after she had been repaired her tardiness became irritating. Murray had also lost one anchor and broken another. His ship sailed so ill, in fact, and required so much attention, that she dragged on Flinders' vessel; and Murray had given many proofs that he "was not much acquainted with the kind of service" in which they were engaged. On October 18th, therefore, Flinders sent her back to Sydney, with an expression of regret at depriving Murray, who had shown zeal to make himself useful, of the advantage of continuing the voyage.
