: Good Points!!!

: Help me here. I felt hard chined hulls turned faster when edged or tipped.

With sufficient rocker you can turn a boat in it's own space. No edging or tipping needed. How much faster can you get? That applies to both round and hard chine boats.

: And Nick's book on page 8 shows some good pictures of more secondary
: stability. It indicates hard chined hulls also have more secondary
: stability in the design.

: Narrower, more rounded hulls are easier to tip/lean into waves which is a
: type of stability but it is dependent on paddler skill, judgment and
: bracing. Often a large person can lean/edge a hard chine wide boat more
: easily than an small person can a more rounded hull. Lots of relativity
: here.

Overall width of the boat has a lot to do with stability, too. I see you linked the terms "Narrower" and "more rounded". I don't want to get into some frivolous word analysis, but I think you express the common perception that rounded hull boats are also narrower. A wider boat with a rounded hull is more ovalshape) would have more stability than a narrower one. In all designs stability tends to increase with an increase in width.
