The M/V Tustumena, one of the ferries, tied up at a dock in Kodiak. The big blue object on the back of the boat is part of the elevator for putting cars in the ship's hold.
The Alaska Marine Highway or the Alaska Marine Highway System (AMHS) is a ferry service operated by the government of the U.S. state of Alaska. It is based in Ketchikan, Alaska. The ferries have many different ways of being used. Passengers can stay inside in lounges or individual cabins, or can stay outside on the "sun deck." You can also bring a car or other vehicle with you for more money. The ferries operate along the coast of Alaska and also out to the Aleutian Islands. They also run all the way down to Bellingham, Washington sometimes.
