Mmmm, I need to do some experimenting then and see how it affects my boat.
Without trying it, I would have thought you would not tirm up or down at displacement speeds. That would leave the prop to push the boat along - flat, rather than slightly up or slightly down.
How do you trim your boat if you want it to come up onto the plane then ? Trim it out - to lift the bow ?
With the little/limited experience I have had it does seem my boat comes up on the plane in a different manner to a normal V shaped hull. I reckon some runs with a note pad and co-driver are in order.
Any excuse for messing about in boats
