If they have somehow taken away the negatives of the tunnel hull design and turned it into a net positive, then by all means,  that’s a good thing. 

But I kind of doubt it.

Basically you're just moving the hull line deeper so that the prop can run a bit shallower in relation to it.  The end result though, as far as how shallow you can safely run without bottoming out the skeg is darn close to the same.    When you throw trim angle into the equation it deminishes even more for the tunnel hull.   Tunnel hulls require a lower trim angle since there is less support at the stern.

Take a 6"x6" piece of aluminum foil and notice what the configuration of it has to be in order to float the most pennys.

Take a minute and look. Not even remotely stock. Draft while fishing, motor position during “normal” use all different than what you can skim over under motion.  

The firmness of the bottom of the lake makes a little difference too.  If it moves, that helps.

Pictures looked as though only at the stern was the hull lower in the water, but the argument (in my head) for having the prop wet with a 9" prop made me think that there was some mistake/misprint. Maybe it was 13"?

Then again if they can't get into the shallows, why are the other guys whining? Looking for ways to disqualify these boats?

There’s a good YouTube video where Ott goes thru the back end too. The plume is what the whole rig depends on. Exaggerated version of what we do with jack plates and set back on a bass boat. I get the rule change on these, only of use by a few and available (in addition to glass tournament rig) to even fewer
