I'm not an engineer so who knows if it would work but a flat bottom boat could be easily re-configured to do a side by side test.
Design would be a derivative of a standard bottom boat but would have air holes underneath, the bottom would look something like this;

It was because he felt the ventilation gave a negligible improvement.
All the SVL Extreme's are running simular speeds with or without the "ventilated step".
The first 29 Shotgun has a "vetilated step" but we have not cut the ducts in yet. We wanted to run the boat without it first to check the speeds and then cut them in later to see if there are any gains.

I wonder what it looked like?
