: I'm preparing to build an 18' x 21.6" strip kayak and an 18.5' strip
: USCA spec C1 racing canoe this winter. Excluding the affects of rocks
: scraping the glass, is 2 ounce/yard cloth strong enough when applied to
: interior and exterior? I will reinforce the bow and stern areas and any
: through-bolted points. My main concern is the canoe C1 shape having
: adequate stiffness using 1/4" strips. Additional interior bracing is
: not a problem.

I glassed a 19' X 17" kayak years ago using 4oz and it held up well. I've tried 2oz a couple of times for small projects and had trouble with it "floating".
