State challenged the acquisition by Lynden, which operates Alaska Marine Lines, of Northland. The companies are the only two competitors in the market for marine cargo delivery to Southeast Alaska. The parties reached a settlement under which Northland will operate as an independent company under Lynden. Sitka-based Samson Tug and Barge will lease space and equipment that previously belonged to Northland, effectively replacing Northland as Lynden’s competitor in Southeast Alaska. The Attorney General’s office will monitor shipping in Southeast to make sure the market remains competitive.
