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.
