I thought you were planning to circumnavigate Delmarva this coming spring!?
More seriously, would it be at all possible to unbolt the deck and flip it over to do this work? It sounds daunting, but I think it would save you a ton of time in the long run and also yield much better results.
lol, exactly why I don't want a squishy deck between me and the atlantic.
And besides, I tight deadline is always good motivation.
From what I've read, you need to haul the boat for "deck removal", and also make a jig so the FG deck shell doesn't twist in odd directions while you're repairing it. It's also considered to be extremely hard to refit the deck to the hull. Most of the time one or the other has tweaked while they were apart, and now doesn't fit properly.
