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

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.
