I think back around 92-93 When Fountain had their 1st Canopied V bottom ( Dragon Lady or Carlos & Charlies) and where trying to set the V bottom record they found that the rounded roof on the Canopy was lifting the boat wrong, they had more speed ( RPM & Power) left but it kept lifting the rear of the boat and caused ill handling. They changed/Moved the top of the canopy to suit. I guess it must have worked...IDK :)

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.

me too, just bustin yer balls... relax its all good...rm

We found ( on Motorcycles) If you make the front fender more like a Russian submarine. ( rounded looking) You get 4 mph at the traps at Daytona. Aprox 195 mph. This front fender was tested and designed in a wind tunnel
with a rider on the bike. ( I believe the tech did have a beer in his hand)
my point is the front
may be the most important.

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.

No,no, no.. just a flaw in your process.. you just have to look backwards while drinking!! Now, if you hit some waves while performing this act, your rear occupants might be a lil upset. But they rarely help with fuel anyway so tuff.

We found we run faster if we put the pointy end at the front.

and thats not always the way the SVL guys run :D
