The plan in action! After failing with the 1/8" rib material that I used on the hull (short pieces are hard to bend), I decided to try the real thin stuff I used on the cockpit rim. Four laminated layers of this worked so well and was so quick, I've decided to lay out temp stringers for the whole boat and do all the deck ribs this way. If I'd known this when doing the hull, I would have done the same there.
