It's an interesting design, but I'm confused about the tunnel system.
Looking at the drawing, it would appear that the prop sits half way
out of the water.

Than can't be very efficient.

I'm confused too, as there are no good photos of the tunnel/prop, and
I don't know the engineering..

"That little rooster tail is always there either in deep or shallow
water. I think it is a result of the "outflow" from under that
complicated hull form re-forming itself back into something less
complicated... a dissolution of confluences or something. There is
very little disturbance to the sand on the bottom as the boat
passes... doesn't even smooth out the ripples."

That "dissolution of confluences" sounds like you, so it's no wonder
we're confused (-:
But I don't doubt it gets terrific mileage with that Kubota.
It is built real light, and I expect it suffer some if "up-scaled."
