RE:[Paddlewise] Secondary stability

I don't really like the idea of picking some arbitrary slope and 
seeing where it creates a tangent with the curve. Because this slope 
does not have much meaning relative to the stability of that 
particular boat. If we are going to choose some arbitrary point, I 
would prefer something like: "The point where the slope becomes less 
than 50% of the maximum." The percentage is arbitrary, but at least 
it gives a reading that is stays consistent relative to what the 
paddler is feeling as the boat is tipped.

In this way a boat with a low curve can still have some metric of 
secondary stability.

If the relative difference between the righting arm at the steepest 
slope and at the X% slope might show show what we are seeking. If the 
relative difference is great, it would show that the boat has a wide 
zone where it is relatively safe to stay tipped, while a small 
difference would show that the transition is fast.
