Well, since my last question, I've become adept at 'playing' the decks of my sailboat by tapping with the end of a large screwdriver handle.
Most areas are only damp.
Problem is, now that I have drilled a couple hundred of these holes in an effort to perforate the skin and encourage the core to dry out, I am finding that there are still MORE areas with wet core. This includes much of the foredeck and parts of the cabin top. I realize that cutting out entire sections of the deck is an option, but the deck makes quite a few compound curves where the foredeck rises up to the cabin top, and the forward hatch opening is located right smack in the middle of the area that's the most saturated. I'm also nervous about trying to separate the outer skin from areas of core that are still fairly well bonded. I don't want to damage parts that are still intact.
