Bohannon is the only one who gets it.

Suggest reading Bethwaite's "High Performance Sailing" for an exhaustive, ACCURATE answer.

Raking changes the centre of effort which will have an effect on heeling moment and pointing ability.

Pitchpoling, in a nutshell, comes from the boat being ultimately overpowered. Bethwaite's answer is to get the boat out the water (planing, or foils). Or, I suppose, you could lengthen your bows.

And beachcat rudders would VERY seldom cavitate (create low pressure enough such that air 'boils' out of the water).

They VENTILATE (drag air down the edge, side, wherever of the rudder such that the rudder 'dissociates' from the water around it.)
