I hope you're aware that steeping onto the scoop is not the same as the whole hull immersing?

I'll stick with my old fashioned almost full keel, moderate displacement (20k) Irwin 38 CC with a SA/D of 16.7, with a pounds per inch of immersion of 1390 lbs (per Irwin).
Apparently not.

Step onto the stern of a skerry cruiser or otherwise relatively slim boat and/or one with "flared" ends looking at it in profile, and you'd get even more of that zee-zaw motion. That is not the same as lbs/inch immersion.
