Wood in stringers??

[crsavage1]

Working on a late 60's Moesly hull 20' and was grinding out a terrible re-fit someone did when I discovered wood in the stringers. It appears as though there is wood in the center stringers and bulkheads that seems to be almost suspended and sandwiched in fiberglass. Problem is, it all appears original but I thought the stringers were hollow, or supposed to be.

Left me with a feeling of only a few possibilities as I try and figure out how to proceed. 1. just open the tops and grind/pull/cut the wet wood out and move on. 2. cut the entire stringers out and replace although that could lead to some twisting in the hull if not properly supported etc or 3. close them up, cover with new glass and move on.

I also was a little concerned that could it mean this is not a SeaCraft? No HIN due to it's age but it has been titled/sold as a SeaCraft.

Anyone had this type of issue before? I downloaded Carl Moesly's patent and just for kicks took some measurements on my hull as compared to the dead rise angles on the patent...they were close but the patent doesn't specify the length of the hull. Not sure if that matters.

Pictures show where I cut the stringer open to have a look and some of the wet wood I pulled out. The stringers are much wider than the wood or the fiberglass sandwich within so it's confusing. I have videos were I explain what I am seeing if that would help.
