Tphoon chainplates--delamination and bulging deck

[Peter Guerrero]

My Typhoon is 27 years old. I've noticed some bulging areas on the deck in the vicinity of the chainplates. When inspecting the chainplate attachments from the inspection portals inside the cabin, I also noticed some delamination of the fiberglass and that one chainplate attachment had actually pulled thru the first layer of fiberglass. Interestingly, this delamination is on the side with the LEAST bulge. Both chainplates are firm and do not appear to be loose.
Stays are also fairly loose to eliminate any undue pull on the chainplates, so overly-tight standing rigging is unlikely to be the cause of the bulging. Questions:

1) What else should I do to address the bulging? For example, should I remove and remount the chainplates in the event water is getting into the fittings causing the deck core to get wet and bulge in the vicinity of the chainplates?

2) Should I fabricate a plywood or metal reinforcement bar to attach to the underside of the deck where the delamination and pull-thru of one attachment has occurred?

Peter: A few questions for you. Do you have a mast support post in the cabin? If not, look at the same level as the deck. Can you see a depression around the base of the cabin housing on the foredeck? Does your cabin housing look as if it was pushed down where it joins the deck? If so, does this cabin sag connect with your bulges by the chainplates? Check these out.
