Let me clarify. The carboard is trapped between the keel and the bilge box. It is sealed inside and the only reason I found out about it is that I had water leaking in through the hull/keel joint and I had to grind the epoxy out as I followed the moisture. Then I tried to clean up the space around the boxlike sump (bilge) that is encased into the keel cavity. It was impossible to remove the cardboard so I dried it as much as I could by soaking with alcohol and sealed it in again with epoxy.

I'm wondering now if the cardboard is just used as filler/insulation between the cutout in the keel and the fiberglass sump.
Thanks! that's good advice. I just wanted the boat back in the water so I didn't do a lot of research at the time. Now I have a year or two to prepare for the next haulout.
It looked like the cardboard was just like insulation but it is impossible to dry it properly and it will trap moisture that gets sealed in.

blt2ski Looks like what is going on with my 22 yr old Arcadia. The yard I am at, says this is "common" if you will. My bolts are encased too.

You may want to go to www.jeanneau-owners.com and post at that forum, and see if others are having the same issue. I did not have this issue 2 yrs ago when I bought the boat. Currently the boat will be put back in tomorrow, after the keel has been cleaned off, new epoxy and sealent ie 5200 along the keel to hull are you have the same issue with. This should be good for some 6-8 yrs. Or at least I have been told.

The cardboard is enveloping the sump box around the sides and bottom, and can be seen when I grind out the the filler that was used to fair the only side that is open. There is less than 1/4" space between the sump box and the metal round it which is filled with the cardboard. I agree that the cardboard should be removed but it is impossible. I was hoping to hear from anybody that has seen this before, or some ideas to get rid of moisture in the cardboard before sealing the whole thing again.
I'm trying to get ideas that I will try next haulout. Thanks for everyone's comments.

sailingdog Ugh... you need someone with long arms and small hands to fix this problem... A chimpanzee would be ideal... What the hell were they thinking?

Also, why glass over the bolts, if they are inside the boat.... if you ever have to tighten them, you have to get rid of the glass. I think the real problem is that the hull-keel join isn't tightly sealed, as the bolts have loosened or something has compressed—and that is why you're having such a tough time sealing the area.

What I would recommend is that you un-encapsulate the damn bolts and tighten up on them after cleaning, sanding and re-bedding the hull-keel joint with 3m 5200 or a good polysulfide sealant. Then, after tightening up the bolts, I would recommend you glass over the hull-keel join on the outside of the boat. If it leaks after that, the water is coming from someplace else...

Here is the look from inside. As the image shows the small bilge is inside the keel. What I am not able to show is that the keel pocket fot the bilge is only open on the port side, so it's very hard to clean out the space and fill with some sealant. Besides, that space was filled with corrugated cardboard which absorbs water and makes cleaning even harder. Any atempt to clean and seal I think is hopeless.

What yard are you in? I might be able to meet you there and help come up with some ideas. I am planning on buying a Jeanneau so I am interested in their issues.
Thanks for your interest, but this was a few weeks ago. The boat is back in the water. For clarity this picture is from two years ago. Back then I sealed the joint with 3M 5200 and that part was good after two years. I think I have pictures of the work being done this year but unfortunately I haven't been able to find them. I'll come back if I find them.
