Cabin ceiling issues

This was the most glorious boating weekend imaginable, but seeing as I was still trying to cough up a lung and sick as a sick dog, I decided to be smart and not leave the dock.  (The downside to traveling a lot for business is that airplanes and really really long travel days tend to lead to nasty colds.)This seemed like a good opportunity to address the leak in the cabin ceiling issue.  I’m stumped by where the water could be getting in from outside.  The obvious choice is the lifeline rail base, but it has been resealed, so I don’t see where water could be getting in.  I can’t find any other place that water could be draining from, without stopping off somewhere else first.  I think Michele’s comment about it being damp prior to repair may actually be the case.Here’s a photo of what it looked like prior to my attacking it yesterday with a dental probe. It turns out to have been a problem spot for a long time, as what peeled off was a varnished-over fiberglass repair, under which is damp wood. So what I have done is peeled off all the bubbling, green fiberglass, leaving the wood below.  We should have good weather for a while, so I’m going to give it a chance to dry.  Then I plan to pull off and reseat all the lifeline rails (it will give me a good chance to inspect them anyhow) even though I don’t think this one is still leaking.  Once that is done and the damaged interior is dry, I’ll figure out what to do about the aesthetics.  My first thought is that since its a relatively small area and if the wood isn’t too badly rotted, to try to salvage it using a penetrating epoxy.  Otherwise, I’m afraid I’ll have to cut out and patch a small section of the cabin roof, and I doubt my ability to do that. Thoughts?  Volunteers to help me reseat the lifeline rails – I think its a two person job? Aside from that, I also spring cleaned the boat inside and out.  Washed the cabin down with Murphy’s Oil Soap so it smells great, and washed and waxed the topsides.  Right now, the Indian Summer is a sparkling, pretty boat with a fresh clean scent.Next weekend I’ll wax the hull.
