I was reading Thomas Hill's "Ultralight Boatbuilding" and in it he recomends sheathing the outside of the hull with Dynel or Xynole, because they have better abrasion resistance than fiberglass. Does anyone know anything about these fabrics? Would they be better than glass on the outside of the hull? How much do they cost? Where do you get them? What doe the look like? What is their weight? Have I missed any questions?
