its a common fix for aircraft wings,to run fences so slow the transverse flow, reduce vortice energy lost in the wake. What they are after is adjusting the power required to the lift gained.

So Im thinking, in similar ways there is that possibility to lift the hull no matter how much, but drastically reduce the spray which is pretty amazing in the video. What I think Im looking at there is a lot of otherwise lost energy.

I know that a sort of chine lump is common on power boats, but I dont think that would be that effective here, and doubtless it would weigh more. I tend to think there are better fixes such as a fence, or an inverse notch or sawtooth. What happens is they generate a high energy vortex which will suppress that transverse flow and suck up that virtual waterspout.

Inevitably it would generate lift as a consequence, but Im also thinking is the flat bottom (looking longitudinally) might not be the most ideal form.

Perhaps a profile that concedes an amount of chamfer. Thats something way outside my area so its open to critique.
