Sure - flexing a boat absorbs energy. But what is less efficient? Flexing a boat and allowing one hull to change it's angle of attack to an incoming wave so that it's stern is still in contact with the water....OR.....driving in the front 1/3 of the boat (including the deck) sumberged into the wave while elevating the stern? Secondly, as the leward bow comes up, it allows the rig to rake back slightly and tilt to windward making it more efficient...don't the ORMA60's have canting rigs so they can lean them to windward?
The question is intended to be rhetorical but I think there may be something to it in some limited situations.
