And now you understand my problems. Problems plural 'cos first I had to go through such things myself for the kid and second I meant to and didn't write the original equation as
Regarding the current board, my initial reaction is that the tail channels look too bulky. However, having said that, it depends on what type of wave is intended to be ridden and what experience is sought. I've ridden boards people have raved about and not felt the same way. I also tend to like more curved lines (I can see how this can go wrong as I type) .
However, the only really proof is in how it rides. Great workmanship there.

Not sure what you mean by "too bulky."
Agreed the important assessment will be the qualitative comparison to what is out there. And what you like.
The objective is low drag, improved tracking/control -- without fins.
By bulky I mean thick. Attached is a photo looking down from the tail of my favourite board - it is number 7 in a series, refining an original design of Larry Goddard.

What is your thickness?
Tail thickness is determined by channel depth which is not a fixed constant. Or vice versa...
I suppose it would be possible to shape a ""torso/chest well" into the deck to decrease thickness overall. And add belly to the nose for further thinning.
It is likely the channel effect will require riding weight forward to trim.
From someone who may have never have solved a calculus problem (Doc I'll be contacting you for tuition. Your website tuition was much appreciated, only joking about the maths) I have a simpler alternative to the grants application, though in covid times it could be problematic. A Swaylocks travel board. Another gets made, share it around and notes get taken and compared. I know Krusher likes shorter boards, 48" seems ok by me.
3.66
3X-1=10
add one to both sides
3X=10+1
divide both sides by three

3X + 1 = 10,
senility strikes again.
doc....
Doc- so does eyesight. When I looked at it on my laptop, I thought your equation read "3x plus 1 equals 10". Misread it! Damn it sucks gettin old.

The channel could be used in any shape.

It's hard to measure, probably 1/4" on wing and 1/2" at tail, flatter section, but it is a curve, so tricky to be exact.
This photo is of a board from John Galera.
I'm off to work now, happy to chat later.

So far, the Galera boards I have seen use linear channels.

Yes, like pontoons, with the foam scooped out down the centre, which is fibreglass like a spoon.
