Well, you have the issues defined, the tear out mostly complete, and a basic plan to make the repairs, I'd guess you'll be able to make it on the water yet this year. Lets see, when does construction season end and winter begin in MN, October 15th? Just kidding, one possible issue you might entertain is supporting the boat hull before laying up the glass and wood components. If it is just sitting on the trailer, it may be flexing the hull in a manner you wouldn't desire.
