Yes. Your chainplates are bolted thru the solid glass so moisture in the deck area doesn t actually weaken the system. But, if not remedied, sooner or laterMessage 1 of 15 , Jun 4View SourceYes. Your chainplates are bolted thru the solid glass so moisture in the deck area doesn't actually weaken the system. But, if not remedied, sooner or later that leakage makes a real mess of the deck. As soon as I return to my boat, about June 21, I'll take and post photos of my chainplate islands. They totally solve any leaking issues but the deck needs to be repaired and solid before considering such a remedy.

Subject: Re: [J28Sailors] Re: Questions for the group
I am presently re-coring the area around my chainplates. I suspect that ALL of the boats have this issue to one degree or another.You can probably live with it for a while. I plan on keeping the boat for a good length of time and wanted to prevent it from getting any worse.
I got a lot of help from David Hastings. If you email me directly, I will send you the advice he gave me. Its rather long to post here, but very helpful. He was very kind to take the time to walk me thru it.my direct email is sailingmaster@...
When I bought the boat, my surveyor said there was moisture at the chainplates and the tracks. I am happy to say the area around the tracks is dry as far as I can tell. They are removed and I have drill afew extra inspection holes andfind just dry balsa.Around my chain plates was another story. T he core around the chainplates was completely soaked about 1 foot forward and aft rand inboard to the cabin side. There was a lot of rot in the area immediately at the chainplate.At first, I tried the short cut method of drilling holes in the deck, drying and re epoxying (see Don Casey et al) DO NOT DO THIS! The area will not dry and you will probably find more rot than you think is there. You will assuredly find wet core. Due to my haste, I am going to end up with a visible painted section in my deck.
After my mistake, I decided to go in underneath. I cut away a section of the headliner aft of the bulkhead on both side (chain plates already removed) and then I opened up a section of glass to expose the core, this let me see what was really going on inside the deck. I removed a lot of wet core and found still good but wet core that I was able to dry with a fan and space heater.
Next, on the starboard side, I removed the hanging locker and repeated the same process on the forward side of the bulkhead. This was not too difficult, but a royal pain in the ass just figuring how to get it detached!! I am about to do the same to port, but I cannot seem to get the cabinet out, even after removing all the fasteners. I may work thru the cabinet door though..luckily on my boat the moisture/rot was much worse on the stbd side and I suspect there is very litte to remove to port.
I would recommend investing in a FEIN MULT-TOOL l to do the cutting and removal of the glass/balsa. It is much better than the copies and does the job NEATLY and quickly with little mess and not blowing dust all over the cabin.
Next I am going to epoxy new balsa in place. There are two schools of thought on this. One is pressing a large section of balsa back in and bracing to hold it in place. the other is to put it in in smaller pieces, wetting out,then coating the balsa in thickened (to peanut butter consistency)and simply working a small section at a time. Then fill any gaps with thickened epoxy, sand and cover with new glass. I am going to use the second method based on David Recommendation and the fact that it is not a structural area that needs a lot of strength.
When cutting out the glass, I am told that you can be carefu land save the original cut out out piece and re lamintate it when the job is done.........good luck with that! The glass around the rot came out easily, but ther rest was still solidly bonded to the wet balsa and was a royal pain to separate, In the end, i found it easier to section out in smaller areas, cleaning as you go with a shop vac)
There are several epoxies you can use. West is the best known, but its very brittle once hardened. You can use West GFlex, w hich stays a little more pliable and will work if there is a littel moisture still there.I also checked out Smiths and MAS. I ended up with the MAS based on recommendations from some boat builders at a local show (they were the ones that explained the differences to me.)
I am going to use Smith's CPES to seal the wood around the holes for the genoa tracks and then re-bed with 3M 4000. Many use 4200, but it will not bond with both METAL and FG. Again, another save but theboat builder guys.
I am going to start taking some photos, and will post soon on the yahoo page
Let me know if I can help you further. I was going to try to buff out my gel coat this year, but due to this project there will not be enough time before I launch late april. I would like to know what your find out for next season

I have been trying to buff out gelcoat oxidation with a buffer and Rule Restorer and Wax. Not sure how it will last. Did you wet sand,then use rubbing compound, then polish?? I am trying to do it in one step. Advise?
I also am thinking of repairing some wet balsa around my port chainplate (10" square)from underneath so as not to damage the deck from the top. I would love to hear how this is going for you!

The hull was heavily oxidized when I bought the boat, and I just spent days wet sanding, compounding and polishing the gelcoat. I learned a lot in the process, so if anyone has this type of project coming up, I might have some helpful tips.

Does anyone know what thickness the balsa to use? and tips or advice for refinishing the ceiling after this is done? The repair is going much quicker and easier than I thought...just trying to gather as much info from anyone that has done this. David Hastings did this repair on his boat and has a lot of good ideas i can forward if anyone else is "in the same boat" as me :)

I hate the chem strippers to begin with and since the deck is opened up and drying the use of water etc is out of the question at the moment....any thoughts
