as the likely winner of the fastest circumnavigation prize, though Francis Chichester privately expressed doubts about the plausibility of Crowhurst's progress. After rounding the tip of South America in early February, Moitessier had made a dramatic decision in March to drop out of the race and to sail on towards Tahiti. On 22 April 1969, Robin Knox-Johnston was the first to complete the race, leaving Crowhurst supposedly in the running against Tetley for second to finish, and possibly still able to beat Knox-Johnston's time, due to his later starting date. In reality, Tetley was far in the lead, having long ago passed within of Crowhurst's hiding place; but believing himself to be running neck-and neck with Crowhurst, Tetley pushed his failing boat, also a Piver trimaran, to breaking point, and had to abandon ship on 30 May. The pressure on Crowhurst had therefore increased, since he now looked certain to win the "elapsed time" race. If he appeared to have completed the fastest circumnavigation, his logbooks would be closely examined by experienced sailors, including the experienced and sceptical Chichester, and the deception would probably be exposed. It is also likely that he felt guilty about undermining Tetley's genuine circumnavigation so near its completion. He had by this time begun to make his way back as if he had rounded Cape Horn. Crowhurst ended radio transmissions on 29 June. The last logbook entry is dated 1 July. Teignmouth Electron was found adrift, unoccupied, on 10 July. Mental condition and final philosophical writings Crowhurst's behaviour as recorded in his logs indicates a complex and troubled psychological state. His commitment to fabricating the voyage reports seems incomplete and self-defeating, as he reported unrealistically fast progress that was sure to arouse suspicion. By contrast, he spent many hours painstakingly constructing false log entries, often more difficult to complete than real entries due to the celestial navigation research required. The last several weeks of his log entries, once he was facing the real possibility of winning the prize, showed increasing irrationality. His biographers, Nicholas Tomalin and Ron Hall, believe that faced with a choice between two impossible situations—either admit his fraud and then face public shame and likely financial ruin, or return home to a fraudulent hero's reception, and then have to live with the guilt and possible subsequent unmasking—Crowhurst descended into a "classical paranoia", a "psychotic disorder in which deluded ideas are built into
