The date is now Dec 41 and the last available missions for my boat type at that base are for Oct 41. Thats were things go wrong, there aren't any missions in the system for me.

Is there a more involved fix, like forcing a boat transfer, or forcing a change of boat? Or reverting to a previous save and then fixing things from there?

in a word, No.
Start a new career with another boat, in another base.
