A Hong Kong-built junk that sailed to Britain in 1997 to mark the handover is likely to remain 3,900 metres beneath the Indian Ocean after it sank on Sunday. The 18-metre Precious Dragon sank 200 nautical miles off Sri Lanka after it ran into heavy weather. Five crew members were rescued by passing vessels in a joint operation co-ordinated by the Marine Department's emergency centre in Hong Kong. They were Peter Glockner, Hans Joachim Brumner, Tamer Robert Salameh, Lawrence Lagnado and Luis Miguel Rego. Summy Chu Wah-sau, a senior officer with the department's maritime rescue co-ordination centre, said it was highly unlikely that the junk would be raised from the seabed, as it would cost an 'astronomical amount of money'. Mr Chu said raising a sunken vessel from just 20 to 30 metres of water would cost at least $1 million. The five crewmembers were rescued nine hours after they sent a distress signal revealing their location at 5.30am on Sunday. The Marine Department called nine ships to the area after the Sri Lankan authorities were unable to arrange a rescue because of problems with their radio equipment. The vessel is owned by Briton Marc Cuthbert, who sailed it to London in 1997. But it was reportedly brought back to Hong Kong in 1999 for refurbishment.
