    was this a bad idea?

    [​IMG]

    It occurred to me that reglassing in the side decks after replacing the coring would be easier than trying to replace the coring upside down...so I spent yesterday removing the rub rail and cut out the port side deck (upside down in this photo). The crappy 3/8'' coring that was installed at some point came off with a crowbar and by hand. I watched carefully and did not see the hull sides settle or otherwise move when I cut it.

    This way, I can get some sawhorses out and work on the coring in the open rather than trying to do it upside down and pull the new core up to the deck with screws through the top. I'm thinking with the windshield framing removed I can get some additional physical help and pull the forward deck off in one piece (would rather not have to cut it in half but might have to, since I can't get any lifting equipment in the barn).

    Is tackling the side deck coring this way a good idea?

    The side decks on these are a common problem area, which often affects the sheer strake too. I'd want to work from above too and is a practical approach, though more effort. The foredeck will make you cuss, unless it too has a bit of softness in it. When I run into these jobs, the usual course is to assume the foredeck is nearly as bad as the sides, particularity around the carlins and other penetrations, so I just yank it off. It's easier to replace then restore, so . . .

    You've mentioned them before, PAR, but what are carlins? Are those the transverse beams under like the foredeck coring? And the sheer strake?

    I think a good amount of the foredeck coring is good but there's obviously still a lot bad at the sides so it seems that total replacement is more practical rather than piecing it in.

    Carlins are bits of framing around deck openings. Sometimes they're completely under the decking others serve as a trimmer and carlin, with part of it sticking up through the deck, like a hatch opening. The carlins receive the edge fasteners around the perimeter of the opening, so moisture can get in, through the fasteners as well as the contact patch on top of the carlin/decking interface. This is also a place where you can have more movement than others, because the frame elements are generally fairly short and don't have a lot of purchase on neighboring elements.

    Thanks for explaining PAR.

    It'll be wonderful to someday bring the amount of rotten wood in this thing down to zero and not have to smell it anymore

    No images today but I have the windshield frame removed and loosened the forward deck. I think I'll have to cut it in half lengthwise to make it manageable for 2-3 people
