Wouter & Ncik...just moving LCB & LCF too much opens a can of other worms and it's not the the answer, maybe a partial answer yes, but you need to address a whole host of other things also. The point was not to lift the bows but to keep them as level as possible at all times, even in some moderately large waves...the power is only on if the mast is stationary.
Warbird....much as I like the dolphin likeness comments, I can promise you I never once considered them when designing the boat. I took the trouble to find the most anatomically correct model of a dolphin I could and then sectioned it....and the sections don't look like anything I'd recognise as efficient at high Rn, but then again Im sure we don't understand nature all that well just yet.
