I have a very limited idea of how S&G works. What I don't know is how much fiberglassing is used. I understand about filleting the joints but how much cloth is used? Is the entire boat covered with FG cloth or just the joints and bottom. Are some parts of the boat just encapsulated with epoxy and varnish. I'm interested in the new 15 ft skiff,,,, how much of that boat is covered with cloth? Thanks.
