Recore the really wet spots. If it's just damp don't worry about it. Mine was leaking water through it when it rained. I decided it was time I did something about it. The length of this was over 6' and the width was probably 2'. Need to do the foredeck and portside at some point. After I faired it and painted the inside, it looked like a new boat.
Very nice job on the deck repair. I agree that the best solution is to re-core and appologise to anyone that took my previous comment to be a better way to fix. I submitted it only as a less expensive alternative and not a long term solution.
Hi I have a swanson 27 with the same core problem.
I would like to see if there is anything wrong with pulling all the inside fibreglass skin off, removing the the core and just replacing it with supporting arches/ribs made of wood or fibreglass ? Seems like less work and I would not have this problem again ?
