I'll be putting a cove pad on it so I'd be pretty locked in. The Greenough thing is what I'm kinda going for. I would like to get some footage if me surfing it at some point. Thickness is 1.5" in the center, the concave deck is .75" and the bottom has .25" single before it goes into the double through the tail. Have to wait a couple more weeks to get this thing in the water.

What's the board thickness in the middle?
In films and stills it looks to me as if GG has his knees/shins very far apart, sort of wedged against the inner edges of the extreme concave on Velo. And given the amount of roll (how up on a rail he would get) there would be a lot of force driving the rail down into the wave face, much like prone with hip and elbow on the rail

It might move the centre of mass into a more hydromantic centre off efficiency

I was trying to explain that moving the hips away from the rail wash, out of the high pressure to low pressure curl. And how your hip affects fluid attachment to the inside tail rail area. I use foam ribs on my boards to place my hips out of the wave face

On my latest board I noticed some drag from my body at various times. When I slightly altered my body position I noticed a small but noticeable burst of speed. On another board it was my elbow that was dragging, which resulted in spray to my face.

Lifting one leg also altered dynamics, to slightly readjust weight.

An interesting feature of Keith's board is the thickness - overall the board is intended to replicate a boogie board design so it is shorter and thicker than the boards I ride.

The "G" variants have the wide point below center to keep the hips out of the water and a square or diamond nose to encourage a board holding position that places the arms/elbows on the deck, away from the wave face. Plus a deck concave to help keep the rider centered on the deck. I actually try to use a tailblock width equal to the riders hip width plus 1". Object = Nothing in the water but the board.

It could be the surfer rather than the board.
