Thank you for the response Frugel Wife. Was wondering if that area is actually cored. There is brown snot weeping from a lower corner and you get a dull thud when it is tapped. So best guess is that it is cored and rotted. Dosnt appear to be any structural significance there but was cored so that the screws holding the exterior teak had something to bite into. Might just as well be left alone except for the next survey. I am betting that there are many others with the same issue. Boat is in Thomaston Maine by the way. Taking down to RI next weekend. Hoping the fog clears
Owner made a concession on the price that I think is fair. Thanks for your participation and the advise that you have given on this site.
