: * Any kayak is going to have reduced overall stability in such conditions.
: Hard chined kayaks do not do as well in chop as do multi-chine roundish
: hulls.

Interesting; I hadn't heard that before. Why so?

: * Well, we all have our preferences! Perhaps a longer aquaintance with the
: Nordkapp makes this comparison inevitable. The Nordkapp has a shallow
: arched hull, it is not hard chined.

Sure. I was just using it as a basis for comparison, since it'd the boat I have the most time in.

: * Greenland hulls do not have any inherent secondary stability (except the
: wider Polar variety), they fully depend on the paddler to brace to be
: kept upright.

Yeah, tell me about it!

: Adding length to the hull will add negligible secondary
: stability. The wet ride is due to the shallow hull.

Sure. I expect that adding more volume to the bow and stern will help the boat ride over waves more than it does now. Currently, it just knifes through them. The ride is smooth, but very wet.

: * If the bottom is too narrow you will have a handful just keeping it upright
: so secondary stability won't matter.

I understand what you're saying, but I find that as long as the boat pushes back when it nears the capsize point, I can handle low initial stability.

: * Greenland kayaks are fun boats and I'll always have one but they are tippy
: , wet in any sizeable waves and have limited stowage.

I'd say that pretty well sums it up.
