Using a camber or a rocker and then a camber before a step can greatly increase the dynamic lift of a planing hull.

From CFD work I have contracted I know that, if there is enough step depth and some speed, the immediate wake follows the exit angle of the camber. then further from the step it follow more of the average angle of the camber. This makes sense since the further the wake is from the step the more it depends on the water below the top surface of the wake, which intern depends on the average planing angle of the camber.

From experimental work I have done, it appears that the step clears at about 14 mph with a step in planing angle but only a few mm if any of step depth.

My thanks to Matthew R. Kramer, PhD., for his informative answer to my last question on this subject under "John Keller".
