Ok I feel like I have been saved from doom.

I agree it takes a whole lot of work and time to undo glass and epoxy. So I will abandon the the thought of glassing the hatch covers in place and then cut 'em out later. Thanks guys--I have certainly spent enough time re-working things on this build.

I hope to 1. finish the build
2. learn how to post photos ( maybe I can get one of my kids to help me on that)
3. show my three boats

And most importantly get out and paddle.
thanks again for the help over and over.
