I once calculated the total lift at about 80 miles per hour to be about 80 pounds...Doesn't sound like a lot, but 80 pounds up at the bow, can reduce the down forces necessary at the prop via positive trim, by approximately 1200#...This translates into less trim, more thrust going aft(not up), and a propshaft centerline more inline with the flow angle, reducing drags and increasing speeds.

Re: rear wings on boats
My boat came with a wing. I removed it this year and well see if it changes anything.

CigDaze: Nice work, what software are you using? Any comments about what MPH the aerodynamic drag becomes significant. The photo of the spray off the back of the boat showing downward momentum is telling.
