Re: Glassing a old wood hull.
It's certainly worth looking into. If you decide to proceed, hire a surveyor with experience in wood. Since the work was done twenty years ago, any problems should be apparent. All of my boats have been wooden, one had glass added, she worked fine. You lose very little speed. Relative to the size of the boat, the thin skin increase means almost nothing. It probably didn't lower her one inch, if at all.
