The 30-year old boat I bought last fall had 3/8 inch varnished pine planking lining the interior. One plank at the top, next to the hull deck join and a non-opening porthole, was so rotten my finger went through it. I began pulling this away to the good wood, and found that it had been riveted and glued to the hull. After pulling off the rotted plank, the backside of the plank immediately below proved to be soft, punky wood.
I am thinking of using resin or Stop Rot to seal and harden the back of the second plank, and am considering gluing some strips to the hull to screw in the top plank and allow some air behind it. I think that would be ideal for all the planking, but think the scope of that job is beyond me. At least if the top plank gets wet and rots again from an undiscovered leak, it will be easier to replace.
I was very surprised to see the planks glued directly to the hull. In my previous boat, the planks were screwed into perpendicular strips attached to the hull.
Anyone else have experience with this? Recommendations?
