Quite a bit, too!
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.

This is one of the better looking Baja's that I have seen. I don't know how useful the wing is, and I am not sure about the "roller coaster" seating. It also has Merc 850's and 6's which may be a little a$$ heavy. I didn't ask the price, but this would not be my first choice for that kind of coin

My boat came with a wing. I removed it this year and well see if it changes anything.

so would it be too hard to put a wing on a boat and have it help even the slightest bit without using a windtunnel?

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.

i read that "areo dynamics" come into play at around 60 mph and become a major factor in design and performance
