So, is the 28 lb. Nordkapp kevlar, or carbon, or what? I just want to know what Sisson does different that maintains a rigid hull and deck at that weight. I've seen a lot of kevlar boats and they all were pretty flexible in some sections. I'm not saying that flexible is necessarily a bad thing, but if I had my druthers, I'd opt for stiff even if it does weigh a little more. The only really light boats that I've seen that are rigid have a core.
