    Hey everyone, I was checking my boat in preparation to go out for a sail tomorrow when I noticed a bit of blistering on the inside of the hull in the aft storage hatch. After some scraping I noticed that a good section of the plywood that makes up my hull is experiencing some delamination. The entire area measures about one foot by 2 feet.

    Any tips on how to sort this out? I was thinking of just drying it out and throwing a cut patch of fiberglass on it.

    Thanks,

    Wolf

    That should work. It doesn't look like a major structural part.

    As long as the edges are OK, and the next layer is not delaminating (indicating non marine or even WBP ply) you should be fine. I've filled the cracks with epoxy and filleting blend on stuff like this and then dropped on a couple of coats of glass. It works fine, only drawback on one OK deck, was had to paint it afterwards as opposed to a vile stained varnish original!.

    a fex coats of solvent thinned epoxy should do the trick. the vanish over the epoxy.

    Looks like my "minor delamination issue" has mutated into a full blown major repair as an inspection of my amas showed that the same two bulkheads on both amas are both going soft.

    As for a picture of the boat... it's not the best one I have as it was still getting it's new rig tuned in but here she is.

    The softness in the amas is right around that damned forward inspection port.

    Shame man, one of the reasons why I make everything wood free.

    Yeah well it was wood when I bought it so... The next one will be something sensible like foam and fiberglass.

    Further inspection still, main hull is basically solid aside from the delam in the back... Still have to cut the deck open to get at a certain area to get a better look at it.

    Oh well it's just time and money right? I didn't want to get my sailing season started anyways.

    I would actually be suspicious of the wood quality especially ply. Bet it is not proper marine ply or a cheap inferior one passed off as quality. I've had this with exterior grade (WBP) which has disintegrated inside a year even though painted and edge sealed!.

    Then there is fibreglass and fibreglass....gelcoat and paint can hide some wondrous ommissions as I continue to find out ;)

    The boat is definitely marine ply, I know the former owner and he doesn't cut corners.

    It looks like I have some investigative work to do in the main hull but it seems that aside from the bulkheads in the amas the boat is essentially solid. I'm going to be bringing her into the workshop at my Yacht Club next month. I'll be starting up a repair log thread as well.
