This is great info. Thank you all for your help.
On the inside I looked at as much of the tabbing as I could see. Sadly a lot of it is covered by furniture and decorative lining. I didn't notice any issues with the tabbing that I could see. The inside of the hull
was absolutely filthy and looked like it had tar smeared all over the inside. I don't know what it actually was but I wouldn't have been able to see anything there.
I did notice that the door frame to the head
is directly over the damaged area) was askew and the door was difficult to open and close. The sliding door was also hard to close (in fact I don't think I ever got it closed). At first I wondered if the cabin
trunk had been compressed but it is a keep stepped mast
so I wasn't sure where the problem was coming from. This may be it. It also may have settled over 25 years.
Unfortunately I couldn't see the keel bolts
because the bilge
was full of water.
I flew in to see this boat so it is now 1000 miles away and I can't easily go back to look at it. Not sure how to proceed but I'll figure something out.
Thanks again all for your help.
