The problem with ferry - the Alaska Marine Highway System, that is - is that with A SMALL EXCEPTION, the northern terminus is Haines/Skagway, which still leaves you far too many miles of charge-less Yukon Territory and eastern Alaska to traverse. There ARE times the ferry continues to Whittier (aka "Cross Gulf")...highly, rare, highly reserved in advance and hyper-expensive.
The problem with trucking it is that that's also expensive, but certainly can be done.
Or you can trailer it yourself...that's what I
almost did when I determined we weren't able to snag enough charges on the route through northern BC and Yukon.
Or you can go to Port of Seattle and get Samson or Tote or AKMarine to barge it up. This latter is, in my opinion, probably the most practical way to go. And
MAYBE you can get it on to a barge closer to your home of San Francisco, which obviously would be less of an inconvenience.
Feel free to PM me for more vague answers...."in a couple of summers", as you write, there may well be other options.
