Even though the designs you mentioned are intended to be built with an internal strongback, and plenty of people have done it successfully, myself included, there is no pressing reason why you need to build a design that is intended for an internal strongback in that manner. You're right. It's flexy. I built a box beam of baltic birch plywood, and it was still flexy, but added heavy and expensive to the mix. I think that I'd build any kayak with a traditional strongback at this point. If you do a simple sprung framework, it won't flex and will be quite stable. Here are instructions from Bjorn Thomasson's site- where you may want to look at his Njord, Hunter, and Black Pearl designs. http://www.thomassondesign.com/building/building_manual/preparations.aspx
