Trying to fill in the blanks.....
You are considering relocating to SW AK. Do you have a job offer, or would you be setting up on your own, or looking for a job with an existing firm? Is this something that you already have experience with, or will it be a new trade for you?
Have you considered which town(s) in SE? With the possible exception of Juneau, all are backwoods compared to the great metropolis of Waterford, ME. Have you spend any time there? It's not for everyone.
I expect 95% of your work would be on fish boats of one sort or another. I expect that's different from cruising boats
