Definitely wait until spring.
I was thinking the same thing. You have a lot of dough invested in that beauty. When you really sink yourself into something like you have with your boat, it truly is what they mean when they call it a "labor of love". Very difficult to put a price tag on something like that. Unless you can find someone that really appreciates the care you've put into that boat, you're going to take a major hit. It's totally on you how much of a hit you're willing to take.
I understand your thinking, but I also believe it's gonna hurt. You seem to have made that boat one of the family. Lot's of time money, memories, etc.
That said, after you find what the market will bear when faced with a hit, wouldn't it be nice to sell it for that reduced price to a family member. That's what I see your boat as. One of the family that should possibly stay in the family. That way you still get to see her periodically.

Just some random thoughts. Some difficult decisions to be made. I wish you well Lumber.
