Ok, I don't understand the physics of how my boat operates. I have a 42' boat with a 38' waterline. I think its 30000 lbs. We have twin 210 HP Cummins with 25X27 props. I can run 8kts at 1400 RPM. The boat rides flat at that speed. Any more than that and the stern starts to squat and the bow come up. I do 9 kts at 1750 rpm but the boat squats at the stern and we through a big wake. It just seems to me that there should be a design that keeps the nose down and doesn't waste all that energy plowing water. Can anyone explain this. Is it bad design or just the physics of a planning hull? Is the shat angle wrong?
