The 22 ton tugboat 97 Samyoung sank off Busan, South Korea near Dudo Island. The 97 Samyoung was towing another vessel when its towing cable snapped and slapped against the side of the tug’s hull causing the vessel to later sink. The two crew on board were knocked into the water and were later found unconscious. The men were taken to hospital, but reported that they had perished. Authorities have placed booms around the sunken tug to contain any pollution released. Reports state an investigation has been launched about the incident.
