Re: 4 winns cuddy entrance sagging
I guess that it is possible. The interior was done at a pretty well known marina on lake St.Clair. I would assume that they would not "fudge" anything but, who knows?
Since it was done by a "pretty well known marina on lake St.Clair" I seriously would take it there with the paperwork and nicely ask them what could possibly be the problem. No sense in getting into a peeing contest with them, but it might be possible the will say OOPs and take care of it. If not they could at least tell you what is the problem and give you an estimate.
Don't know how fare the "pretty well known marina on lake St.Clair" is from you but for my investment it would be well worth the trip there to get an answer.
Should anyone else attempt to repair it, they can always say that it is no longer their problem. As described, I don't think your attempt to shore it up would constitute a repair.
Wet wood dies not shrink very much when it drys, most of the shrinking would have happened during the post cut of the tree and the kiln drying process.
