sole of my new boat produces a pronounced downward flex when walked on. It's solid fibreglass, i.e. not cored. I was wondering if, rather than cutting out and replacing the floor (big, expensive job), I could buttress up the underside with glassed stringers. Don Casey describes this method in his books
, but I'm unsure if it's suitable for fibreglass that has lost
it's rigidity (there is a technical name for this that escapes me right now) and requires the strength to be walked on. If this method is not suitable, perhaps some know of alternative methods to this and the entire removal/replace process?
