This is the America's Cup winner of 1930, an N.G. Herreshoff design and the
last AmCup racer with a centerboard. The wind looks fairly light (although
remember that this boat is 120+' LOA, which distorts the scale) and the boat
is heeling 12 ~ 15 degrees... but look at the wake. Obviously the boat is
moving well. But is it "powered up"?

No it isn't. She's not near her hull speed (look at the stern) and the
wind is light. I'll be she'd be closer to hull speed when heeld to 25-30.
