Fountain, Outerlimits, Phantom.. Has anyone ever wind tunnel tested a V Hull ?
#12
I know when we take the windscreen off of the AT's we get another 1-2 mph. 
I think Bad Boy Boats did some testing with their canopy. IIRC, they popped a mold off of a C5 Corvette and made the mold after such.
Would one be looking to decrease wind resistance on top of the boat? Add bow or transom weight at speed? Provide lift?

Did a quick search and found lots of nothing.. a few little bits, but nothing definitive. Has anyone wind tested a V-Bottom and if so what did they discover? Only reason I'm asking is i have access to a big 3 wind tunnel, one small one big enough for a buss (don't ask how I know the bus fit) and was thinking about building a small scale SVL model and seeing if shaving areas would help reduce wind drag at speeds.
They must be the most aerodynamic because at that speed none of the boat is really creating too much drag in the water imo

I have done a little wind testing of my own on several boats. What I found is that when I stick my head above the windshield at anything over 30-35ish, drinking beer becomes extremely difficult. My conclusion is, stay in a slight tuck, therefore reducing drag while maintaining the ability to enjoy my beer without wiping my entire face after every chug.

Ive been around (government) aerospace for a while and did research with a company in Indiana that makes bicycle wheels (Zipp). No, I did not stay at a Holiday Inn Express last night...
The big factors will be speed and yaw angle. Think of the obvious. A boat is shaped like a bullet. As the speed rises you have to get rid of drag - bow rails, deck hatches and the lower the windscreen the better. Under approx 90 MPH the bottom has more impact than the aerodynamics.
Just read anything on a Formula One site and you will have instant gratification.

Actually I was being sarcastic. ( I thought funny)
On the other hand at least our pointy end remains at the front of the boat when cornering. It's a V-bottom boat and hydrodynamics come in to play much more than aerodynamics. We've figured out hydrodynamics.
