The MV Tustumena is named after the Tustumena Glacier, located on the Kenai Peninsula. The vessel was designed by Phillip F. Spaulding and Associates of Seattle, Washington and constructed in Sturgeon Bay, Wisconsin in 1964. It was built with an elevator capable of loading and unloading vehicles without a ramp. In 1969 a prefabricated 54 foot mid-body section was added, lengthening the vessel to its current size. The MV Tustumena is the smallest AMHS vessel with cabins and is one of only two certified ocean class ferries in the Alaska Marine Highway System fleet. For comfort and safety the ship is equipped with gyroscopic fin stabilizers to reduce rolling. The MV Tustumena is 296 feet long and 59 feet wide, with a domestic gross tonnage of 2,174 and a service speed of 13.3 knots.
