Mystery was a Mount's Bay lugger which made a voyage to Australia in 1854/55. Her passage to Cape Town was so fast that she was commissioned to take mail from there to Australia.

Mystery was a Mount's Bay lugger used for fishing inshore waters. In 1854, seven Cornishmen decided to try their luck in finding gold in Australia. As they were all shareholders in the boat, it was suggested that Mystery be sold to cover their passage to Australia, but the captain, Richard Nicholls said that he would take them to Australia in Mystery.

The boat was prepared for the long sea voyage by covering the hull in zinc, and adding decking fore and aft. They left Newlyn or Penzance (sources vary) on 18 November 1854, passing Madeira on 25 November and San Antonio on 3 December. After this, Mystery encountered some bad weather, and her jib split. The Equator was crossed on 15 December. Trinidad was passed on 23 December and on 26 December communication was made with the brig Callao, which was bound for Liverpool. A letter was entrusted to her captain giving details of their journey so far. The Cape of Good Hope was sighted on 17 January, and Cape Town was reached the next day, after a journey of 60 days. The Harbour Master thought that Mystery was a local boat and did not board her until the crew beached the boat with ease.

Pete Goss, MBE is a British yachtsman who has sailed more than 250,000 nautical miles (460,000 km).

A former Royal Marine, he is famous for his pioneering project Team Philips. He received a Legion d'Honneur for saving fellow sailor Raphaël Dinelli in the 1996 Vendée Globe solo around the world yacht race. During a severe storm in the Southern Ocean, he turned his boat around and spent two days sailing into hurricane force winds, finally finding Dinelli in a life-raft that had been dropped by an Australian Air Force plane shortly before his own yacht had sunk. Dinelli is said to have come aboard clutching a bottle of champagne.

He trained the original set of amateur crews for the British Steel Challenge, and competed in the race on board Hoffbräu Lager, coming 3rd overall.

Goss currently lives in Torpoint, Cornwall, and has three teenage children: Alex, Livvy and Eliot.

In June 2008, Goss launched a replica of a 19th century wooden lugger called The Spirit of Mystery. Four months later, he began a voyage from Cornwall to Australia on the boat, which has no modern electrical or navigation systems.
