The MV Columbia is a prominent mainline ferry operated by the Alaska Marine Highway System, constructed in 1974 by Lockheed Shipbuilding in Seattle, Washington. As a flagship vessel, Columbia has served for over four decades, primarily linking the largest communities along the Inside Passage, including Ketchikan, Wrangell, Petersburg, Juneau, Haines, Skagway, and Sitka. Her typical route spans from Bellingham, Washington, to Skagway, Alaska, facilitating vital transportation for both passengers and vehicles through this scenic corridor. Designed as a substantial ferry, Columbia features an upper deck situated between the main vehicle deck and the passenger cabin deck. The vessel’s vehicle stowage capacity includes two vehicle elevators capable of lifting vehicles up to 19 feet in height, accommodating passenger vehicles along with additional passenger cabins for comfort during long voyages. Her construction and design emphasize reliability and capacity, serving the needs of the region’s communities and travelers. Throughout her service, Columbia has experienced notable incidents, including a significant auxiliary engine room fire on July 2, 2006. The fire temporarily impaired her steering and propulsion systems while she was in Seymour Narrows in Canadian waters, necessitating repairs at Duncan Bay, British Columbia, before resuming service. Additionally, in August 2007, a bearing failure in her starboard engine’s connecting rod led to the engine’s shutdown and a subsequent extensive repair process at Ketchikan’s Alaska Ship & Dry Dock. This incident prompted a fleet-wide rerouting and a suspension of her summer voyages for repairs, with her engines later overhauled at Cascade General shipyard in Portland, Oregon. The vessel has also undergone routine heavy maintenance, including a winter layup in Ketchikan from September 2009 to June 2010, during which her propeller shafting and associated components were overhauled. These repairs and upgrades underscore her importance as a key vessel in Alaska’s maritime transportation network, maintaining her status as a symbol of regional connectivity and maritime heritage.
