[Paddlewise] Rollability Hypothosis

Looking for input.

I have been having some discussions about kayak "rollability". The common
idea is a kayak will be hard to roll if it is stable upside-down. This
makes sense initially, but then again most people can get most of the way
up in a roll. The hard part is getting all the way. If inverted stability
was the most important thing, getting from upside-down to the point where
you can breath would be the hardest part.

I thought that maybe the slope of the stability curve at 90 and 270 degrees
would be a better indication of how easy a boat is to roll. A lower slope
indicating and easier boat to roll, i.e. the effort required to change the
angle fo the boat would be less.

Any comments?
