FYI There is plenty of information out there for you to find that shows radius corners are better than straight. Keep in mind, a 2 inch radius tilted at 10° turns into a 12 inch, or more, radius in the direction of flow, where it really matters.
back at you. got any studies to back your points????

the study you showed pointed out cutting it hard to 18.77 caused no turbulence at the transition point and proves my point.

The study you provided showed negligible turublence with square corners, contradicting your comments, and proving my point.

If we are not trying to fill in the wake, then why bother with a kammback? We could throw on 3 inch transition wings ,and call it done. But "everyone" (including me) seems to think a boattail leads to reduced wind resistance. I think you are missing the point to all this.

Again, I challenge you to give hard descriptive instructions or recommendations for Neon to build his project.

Sniping at my posts with vague descriptions of salt water does none of the DOERS any good.

If you don't like 20 degrees, and you want some theoretical curve, describe how to build the curve. Give specific direcitons how to follow the curve and build the curve for the Neon, and for my suburban, and for my trike, and for my race car, and for semi trailers, and for pickups.

I'm not going to argue and say the "correct" curve is not better than chopping it to 20, but chopping it to 20 with a small radius area is pretty easy to implement, easy to describe, and effective, and I don't know how to BUILD the ultimate correct curve for his Neon.

Do you????????

If you have a better way to DO, then speak up.
