I have a C9.6 that I am restoring. It had some damp and wet core areas (about 30%). While removing the fiberglass to replace the core I do not remember any areas that had delaminated. Exposed layer of fiberglass came out in one piece after considerable effort and any wet core had to be removed with a chisel. Sorry I can't give you a broader answer.Jay T.

total recore

I recently recored my entire deck and it showed no signs of delamination. if the area is small enough you can inject epoxy resin through a syringe (used for applying glue and sold at most woodworking stores) then weight down the area with a sandbag or two.If the problem is more widespread I would call in a pro.

for your informantion read this article

check out the MustangIslandYachts.com website. There is a very interesting article written by a fellow there. It is listed down at the bottom of the front page and says not to worry too much about some blisters. He says that hulls like the columbia will not delaminate. Good luck
