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.
