I helped Beau Reglass his boat. He just mentioned it in the previous discussion. He did a great job... I don't know if he mentioned that he used a very high silica filler loading for the coating, that plus the glass cloth is what made it very tough. Never put all your chips into a resin alone.
His polyester base coat (which was actually a 2oz) for the covering, mainly because of it's great conforming properties and workability. but the strength is from the fact that he used 50" wide glass cloth for load distribution, and lots of silica in the epoxy. This gives his hull a stiff structure (good underway) and the high filler/fiber to resin ratio allows impact to be deflected over a large area. I know that beach he launches off of, I used to dry haul a boat there myself. It's really rocky, so this ended up being a great solution.
