history
The ferries were built at the Vigor Alaska shipyard in Ketchikan . The construction costs amounted to 101 million US dollars . The ship design came from the Elliott Bay Design Group in Seattle .
The Tazlina was the first ship of the class to be christened on August 11, 2018 . Godmother was Donna Walker, the wife of the then governor of the state of Alaska , Bill Walker . The ship is named after the Tazlina glacier . It was delivered on April 14, 2019.
The Hubbard, the second ship in the class, was completed in 2019. It is named after the Hubbard Glacier .
Technical specifications
The vessels are of two twelve-cylinder - diesel engines of the manufacturer General Motors , each with 2,238 kW power driven. The motors act on two variable pitch propellers via reduction gears . The ships are equipped with a bow thruster .
Two six-cylinder diesel engines from the manufacturer Caterpillar , each with an output of 599 kW, which drive two Leroy-Somer generators, are available for generating electricity . An emergency generator powered by a Caterpillar diesel engine was also installed.
The ships have a continuous vehicle deck with five lanes that can accommodate 53 cars or 40 cars and four delivery vans. The usable height on the vehicle deck is approximately 4.9 meters. Vehicles reach the deck via driveways in the bow and stern . At the bow there is an approximately 3.4 meter wide ramp for vehicles and an approximately 0.9 meter wide ramp for pedestrians behind a front visor that can be opened from the side . A landside ramp can be created at the stern. The gate here is about 7.3 meters wide. In addition, in the rear area on the port side there is a side gate almost 5.7 meters wide for loading and unloading in ports without corresponding ro-ro bridges. For more flexibility, it is planned to retrofit the ferries with a side gate in the bow area.
The passenger facilities are located on the two decks above the vehicle deck. This includes a self-service restaurant, lounges, including an area for families with children and a relaxation area, as well as a covered and an open deck area in the rear. Another sundeck is located on the superstructure . The passenger capacity is 290 people.
The ships are operated by a crew of 14 . They are not equipped with cabins for the crew. Since seafarers on US ships are allowed to work a maximum of twelve hours at a time, the voyages must end after twelve hours at the latest.
