I live in Haines, Ak and will be traveling south to Bellingham in a short while. They charge by the foot and my camper is 24 ft and with a room it costs right at $10,000 round trip. The Kennicott is the cross gulf ferry and it only comes down to Bellingham every other week. The winter schedule isn't out yet. The Kennicott with take you across the gulf which is more money. The cost doesn't change whether you put in RV or vehicle, they work on the length only. The Kennicott will run part of the winter most likely but there will be a period where it will go in for routine repairs and so no cross gulf run. There is a second ferry that makes the round trip Bellingham to Skagway and back every week.
