There are a couple of reasons to not used closed cell foam. First, it is a lot
harder to get a good bond to it with the fiberglass. It is the bonding
between core and fiberglass thatgives you the strenghth so the bond is really
important. Second reason is that wood (balsa anyway, I'm not sure about
plywood) is stronger than foam. At least that is what I read when I started
researching boat consruction.
On the other hand, closed cell foam won't absorb water and rot. Which is a
pretty big argument for it, in my opinion.
You may also want to figure out a way to tie the 'new' coring material to the
existing since you are going to create a weak spot at the seam that you cut.
Any with more experience, please feel free to correct me.
