initial stability/hard chines

Hello All,
Is there any correlation between low initial stability and a hard chined hull design? I usually paddle a wilderness systems Alto which is more rounded in chine area. Twice I have paddled a hard chined design (Merganser on flat water) and (W.S. Arctic Hawk) and they felt very twitchy to me. The Arctic Hawk is fairly low volume west greenland looking with fine entry and exit on hull. It feels ok on flat water but when I went out of harbor into Lake Michigan the other day (1.5ft choppy waves) I was totally not comfortable with how unstable it felt in the choppy waves. Is it the hard chines on both of these boats that makes them feel this way? Is it the prismatic co. of the Arctic Hawk that made it seem so unstable in choppy water? I don't remember how fine the Merganser looked on bow and stern but I remember it felt very twitchy to me also. Just trying to understand why the boat trounced on my confidence so.:) Thanks,Kurt
