Ryou-Un Maru (漁運丸; Fishing Luck) (also Ryō Un Maru) was a Japanese fishing boat that was washed away from its mooring in Aomori Prefecture by the March 2011 Tōhoku earthquake and tsunami and drifted across the Pacific Ocean. It was spotted a year later by a routine Royal Canadian Air Force air patrol about 150 nautical miles (280 km; 170 mi) off the coast of Haida Gwaii, British Columbia. The unmanned hulk entered U.S. waters on 1 April 2012, and, after salvage attempts failed, was sunk by the U.S. Coast Guard on 5 April 2012 to prevent the hulk from becoming a hazard to navigation.
