Just a few thoughts
Is there a heavy anchor with chain in the bow?
Are the trim tabs on all the time? Do they hang proud of the of the hull line?
Do they look like they were factory installed?
You can remove just the tabs to test if they look wrong.
It does not seem possible that your boat was sold by Uniflite with that defect.
There must be something wrong.
Wood boat were sensitive to center blocking during storage that would cause the center to cup and cause a similar problem. I can't imagine a Uni doing that with that solid keel, but anything is possible.
Was a belly tank added forward? Batteries?
