The Crimson Polaris ran aground August 12, 2021 and proceeded to break in two off the north coast of Japan. The crew, mostly Chinese and Fillipino, was rescued and brought to safety by local coast guard. The ship was registered in Panama. Photos show the stern tipping up and the rest of the boat listing away from the stern. The rupture caused a fuel leak that spread 15 miles out and there was difficulty creating a fence around it to prevent the spread and environmental impact of the oil.
