Great, I really appreciate the willingness to help. If you don't mind ask him what the opinion on cutting the caps off the stringers and gutting then filling with pourable or rigid foam like divinicell or using a pourable composite like seacast or Nida bond(transom filler)Then re-capping the Stringers.
Thank you.

It will be interesting to find out the opinion from G&S. But from what I have read on this website, cut the tops off, remove old foam, install new foam (2 part) and then reinstall the tops. Refer to Stricks string if I remember correctly. The USCG has a requirement for foam. I would not put Seacast or a hardened product in the stingers. Weight of these products may become a facter. I drilled holes in the bottom and top of my stingers and let them dry. I will reseal them when I seal the top hatch.

This is something I just read...and since I am new at the restore stuff I will be interested in knowing what folks think.

The article stated that you should stay with like material, if you are only replacing sections of stringers etc. wood stay with wood, foam, stay with foam.

I know some of the 21's stringers glass has pulled away from the stringer, now looking for the right and easiest way to fix.

Terry,
Where did glass pull away? Where the stringers are tabbed to the hull?

I saw some past posts from Don (Hermco). looks like leaving them hollow or placing 4lb rigid foam inside stringer cavities may be the way to go. Regardless, I will probably abbrade the stringers and add extra layers of Glass (build them up)

Stringer

Let see if I can explain this. If you take the stringer and pinch it. It will compress. If you try torquing it left and right it will give? twist slightly. Now this does not happen through out the stringer just in certain spots. You can see the stringer glass has not pulled away from the hull. Just that the interior bond to the wood is gone (or the wood is gone). Hope this makes sense.

That is why I am wondering if a pour composite might work?
