That would make sense, structurally. I can't tell what is going on in the picture supplied- he mentioned rot- and it looked like there was wood in there? Or is that some sort of delamination?

There was a 3/8" balsa core between two layers of glass which extended from 4-5" below the hatch to 2-3" from the hull. There was significant rot(some areas were completely gone).

I think after I get the new core in I will build up some reinforcement like Dennis did.

I also am going to coat the inside of any holes I cut with epoxy. I don't think the divinycell, being a synthetic, will be affected by water, but I still don't want any getting in.
