With the changes I made to bow height and cockpit position, it handle great, but I think the narrower beam and greater angle of deadrise should make paddling effort less, and also give it less initial stability.
Secondary stability is very nice in the original design.
I like Pygmy's Arctic Tern, but I am looking for something in addition to my Tern that will be faster and more playful. The kayak I'm building is also an experiment for me. The Walrus does have very little flare amidships, it is very similar to the original SW Greenland designs. I have paddled the Tern, and found it very stable. I am working on modifying a Putz Walrus.
