Deck concave - yes or no?

What feelings do people have on deck concave? I have a Sunova Pilot with concave described below and sometimes I feel like it would be great if it was more pronounced, especially with wider span foils to give you a feeling of moving towards an edge as you move your feet out.

I liked having a nice progressive concave on downhill skateboards, so can imagine similar feeling with the foil, but don’t really know where people are going with this.

We have a concave deck to get the rider as close to the foil as possible while maintaining the volume needed. It’s a soft concave without any drastic edges so it doesn’t trap water on the deck after takeoff.

Benefits of a concave are maybe increased rigidity and reduced deck thickness?

I really like deck concave. The few times I have borrowed a board that has a flat deck I then realize how much I love the concave. I am sure there is a point when it becomes too much but haven’t found that yet.

I suppose the origin for a bunch of the shapers is in surfboards where a nice concave is physically impossible with the requirement for sharp bitey rails, that really isn’t as much of consideration with foils, save for the foam rebounds and tail touchdowns.

I haven’t looked at the geometry of a concave vs flat, but it definitely feels like it gives you more leverage on a skateboard, and it certainly gives your feet a reference for where in the board you are standing, both positives

I built my custom board with deep deck concave 2 cm .
Even for pronefoil and kitefoil pocket boards.
It give finaly the same feeling as your foot on a skateboard , ability to know where the foit is exactly and conpensate pressure.

For me it is a way to have a easier pop up with the hand grabbed on the rail caus it let you more space for your front foot to get placed

I like concave deck, both on prone and on sup. Kind of deep on the sup to add more volume without having too much foam under my feet.

On surf foil, slight concave deck, I like the feel when you paddle, you are locked in, I like the extra control you get from this.
