4'10

Have a board in the works being shaped by Tony Caramagna of TC Surfboards. Tony grew up in the Point Loma and Sunset Cliffs area here in San Diego and has made kneeboards before. He is very easy to work with and I feel I was able to tell him what I have trying to do in my shaping. He was very open to trying out something like this. The concave isn't very deep 3/4" of an inch in the center. The thickness out at the rails is 2.5" and the width is 22" wide. Length is 4'10" and he put his channel fish bottom on it. It has about a .25" concave running the length of the board going into a double through the fins, have it set up as a quad. Will ride this prone as well, just not feeling the shaping anymore. Trying to have a one board quiver which I know is impossible but with what I have planned for the future I may not have the space for multiple boards.

Interesting...do you have a shot of the bottom?

Photo angles can be so deceiving... looks like a round bottom to me!

Looks to me as if it is on the racks w/ deck down so round deck and complex concave within a concave bottom

Actually it has a concave deck and that is in the pic in my first post. Will post another pic of the deck and the bottom tonight

Looks good Paul. But if you knee ride it, you will be banned from this forum.

Finned or finless?

Running it as a quad but wouldn't be opposed to going finless. Getting a set of the Lovelace Piggyback quads.

I feel like the concave deck makes a ridge outside of it on the rail, riding finless i'm usually over right on the rail, with my hip and elbow, would be interesting to see this ridden. I guess it would be more like greenough on a spoon.

What's the board thickness in the middle?

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.

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.
