Well, finally got to use it. Huge improvement. We have always had a strong wave, but with a small usable area. The shaper at least doubled the surfable wake.

Only thing is that on our hull the shaper is about 1/2 out of the water at rest. The shape of our side hull will not allow it to go down any further. So it is working well, but I have to wonder how much better it would if we could lower it a little farther?!?
