Re: Advice on this Catalina 22
I don't remember there being anything but empty space where the foam is, but it's been a while since I sold my 22. I'm guessing the guy was after positive floatation.
As for the glass over the wood stringer, take a scratch awl and probe the wood. If it's solid you're probably OK just glassing it up.
Try going here Catalina 22 - SailboatOwners.com
and ask the question. Somebody over there has seen and fixed this same problem.
