I have a 15' tri hull that the floor was rotted on. I tore it down to the stringers and put fans in to dry it all out. now I am trying to come up with a plan for going back together. My question is do the stringers need to be glassed to the hull if they are composite? could I use something like aluminum and simply PL it to the hull and put a floor right on it without glassing them back to the hull? I want the boat to be solid when I am done but don't want to have to worry about rot down the road and am trying to get it done as simply as I can.
