Do you reconise this hull bottom?

I was thinking scale models (I'm showing my age!), but yea, if you have CFD capability, that's obviously the way to go! Analytical models allow you to quickly evaluate a lot of tweaks and provide good insight on what's really going on with the water flow along the hull! And having a prototype to verify the analytical model is even better! 70 mph on a 25' boat with about 275 hp is impressive! The bass boat guys would be jealous!
