James, I was thinking of it more simplistically - once you get going fast enough so the strakes are out of the water, you're running only on the rounded portion of the hull, which is a section of a circle, so the boat can roll from one side to the other with no resistance. I am sure the air is a factor too, especially for boats with extra horses on the transom.

I wonder if stock power can push the hull fast enough to make the "pad" worthwhile, or if the extended strakes would be sufficient.
