The formerly retired tugboat Polar King is back on the water thanks to the hard work of the Alaska Marine Lines team and many others throughout the Lynden companies. The 50-year-old tugboat was completely overhauled earlier this year and is now back in the fleet and will be towing barges between Seattle, Hawaii, and Western Alaska ports. The 120- by 34-ft. tug was built in 1974 at McDermott Shipyard, one of eight built that year. Four of those vessels ended up towing barges at AML.
