I would say that, if sewn in the manner shown in the video, there is no need for any darts. Specifically, you sew it from the middle to the ends, pulling the slack out of the fabric up & forward. The weave seems to be more shape-able than the dacron weave.

I built a Classic 10, and I have always been concerned that the dacron was not good enough. I do have to say, the dacron is adequate, but I would still like to have a tougher hull. The ballistic nylon sounds good. If you haven't done so yet, I suggest you check "skin-on-frame" kayaks on the internet. There is a huge amount of information out there. A lot of these kayaks are built with ballistic nylon. Skinboats.com offers several choices of nylon to choose from. Here is my concern. When you shrink the dacron to your frame, all goes well on the Classis until you hit the last third of the stern. At that point you really need to crank on the heat to get the material to conform to the hull. I do not think that the nylon will shrink that much. Is all lost, maybe not, you may be able to make it work by sewing in a couple of darts in the fabric, then shrinking it. For that you will probably need someone who is good at sewing, a wife comes to mind.
Hope this helps, Richard

Sorry to revive an old post, but I've been lurking on this site for years, and I believe I am finally building up momentum to undertake building the Classic 14. I'm really tempted to try using ballistic nylon as the skin, keeping in mind the inherent risk of slackening due to humidity. From your previous post it sounds like you undertook using this system on a Classic 12, is that correct? If so, what methods did you use to combat loosening (e.g. skinning wet), and how has the the skin performed to date.
