Once sealed (properly), the migration will slow as you need oxygen to continue the rotting of the balsa. You need to have a professional test the extent of the damage. It may not be as easy as simply running a tap test. If the rotten balsa hasnt caused a delamination from the skin (yet), a tap test may miss areas. The core in the cabin top of C&C 34 was ½ contour scrim balsa. If you decide to do the repair, I can offer some advice as I had to recore over 60% of my cabin top last year.

At the front bulkhead, port side a diesel heater had been installed and water got into the deck around the chimney. I sealed this up several years ago but now the deck has become spongy forward and towards the mast, covering an area of about 1.5 feet square. At the moment it is still fine for standing on but it makes me nervous that it will get worse. For anyone who is familiar with this problem I have some questions. 1. It appears the deck has delaminated from the core, which I believe is balsa. I have heard that once this sets in it will just continue to spread. Is this true, or now that water is no longer getting in will it stop? 2. Is there any way to tell if it is still wet in there without drilling holes in the deck? 3. What are peoples recommendations on how to fix this? Any other advice on this is appreciated. Thanks Don
