Nope not a new idea at all just adapted to my hull.

Makes for a surf able wave with no ballast of course the wake gets much better as you ad weight to a point.
The main difference in mine is no new holes in the boat.

I tested a blade style for nothing other than how they tuck away when not in use.
Couldn't make it do what I wanted.
This is a crappy video of the gate in action with no rear ballast.
The gate is as low as I can mount it witch is a bit to low as you can see by all the water coming over it.
