Chainplate reinforcement

[knothead]

I pretty much agree with all the above.
Some good pictures would really help.
However, I would respectfully suggest that it still might be a good idea to pay a professional to take a look at it for you at the very least.
Even if you choose to do the work yourself, and I encourage you to, sometimes having someone that's done it before explain the process is really helpful.
If you are going to do the work in a DIY boatyard, they will probably have someone on staff that could advise you.
And there are almost always some pretty skilled boat owners hanging around in boatyards.

Just make sure you run any questionable advice by the SailNet crew before proceeding.

Thank you very much everyone,

Yes the picture has taken from inside and crack is on the headliner. From outside there's no sight of crack, softening, delamination or damage on the hull.

I will definitely replace the chainplates (not a big ticket investment and really wise thing to do) and will use backing plates instead of washers.

About reinforcing, I will open the area first and do some damage control. Then proceed accordingly. Hopefully will post update with before/after pictures.

Thanks again for your advise.

My "new to me boat", 1983, 28 ft O'Day has a very similar problem to Tafa's posted pic, however, my boat DOES have a backing plate and I do not see any visual cracking in the glass from the inside. My boat does have the lower back shroud anchored with a rod through the boat to a bulkhead behind the settee. However, the lower front shroud is only thru-bolted to the top deck with a backing plate. When I bought the boat the captain I hired to transport the boat with me (a situation that allowed me to get familiar with my boat in big waters and a 200 nm trip) tightened the shrouds too tight and caused a "canning effect". Is the front shroud important enough to pay to have a "strapping" created, perhaps mounting an exterior strapping thru the hull or.....beefing up the top deck from the inside and increase the size of the backing plate? Thoughts? We want to be safe but we don't want this project to out-cost the cost of the re-sale of the boat in the future. Sorry, no pics, the boat is 5 hrs away, shrink wrapped with snow.
