Well, lets see if I can figure out pics.
It is now Sunday night, we will go back tomorrow and see if we can get into the interior spaces of the boat to make a better assessment. Frankly I am not encouraged but Wife is undaunted. It is a very nice boat and layout if hard used. I'm not sure what bothers me more, the corrosion (could be an isolated spot) or the welding in the aft bottom plates.
First pic is from bow.
Second pic shows the repairs in front of and around the shaft log.
Third pic shows corrosion spot on port hull.
