THE search for two missing fishermen, forced to jump from their burning trawler off Ninepin Islands early on Friday, was called off yesterday morning after marine police decided the men had almost certainly drowned. Lee Kwan, 38, the Aberdeen-based boat's owner, and crewman Li Yaoliang, 48, from Guangdong, are thought to have been swept away by strong currents five nautical miles off Ninepin Islands. The fire was started by an engine-room explosion.
