Recently hauled out my boat so that I could do a bottom job and other repairs that I had been putting off until I could get it out of the water.

Noticed that some pre-existing decay (there when I bought the boat two years ago) in the bulkhead where the chainplates bolt in had gotten worse, to the point where I can drive a skinny pick through the worst of it when I push hard enough.

Looks now like I'm going to have to replace those bulkheads. As I poked around a bit, it looks as if the rot has affected almost every board inside the boat.

I'm contemplating completely replacing the interior with new wood. Is this worth doing? Note that this would be my first project on the boat that would actually require cutting things out and glassing them in. I have some experience with fiberglass from when I was a kid, but not too much. Looking forward to hearing your advice.
