My comment that wet foam will pull away from the glass skin, I used the wrong word. It is supposed to stick to the exterior glass, and the underside of the plywood decks, which I think is the whole Whaler concept, and I know from experience that it doesn't. When I cut out a portion (6"x 4ft or so) in the deck of my 15 footer, to build a rigging tunnel, this is what I found. There were 4 or five screw holes in the old deck that were not properly sealed, and water intruded into the foam for about an inch deep. The deck itself had some rot around the screw holes. The plywood itself was 1/2" CDX 3 core plywood, the same stuff we used to sheet the roofs on houses. So much for using quality materials. Also, when I pulled up that section of plywood on the dry portion, the foam was adhered to it, and on the small wet section, the wet wood was clean of foam and pulled away from the wood which had slightly condenced. I then dug out the foam under the removed deck to make a cavity for the tunnel.

Tom, you're good at giving negative answers as to why someone is wrong, how about some advice on how Kamie can solve this wet foam problem, and rid the foam of water or build a new foam filled deck.
Stick to prop advice, please.
