This is proving what exactly?
Let's face it, if your board is not flat on top or if not using thick and fatty footpads on a heel side, one would need to edge really hard comparing to the flat board. Putting a lot on fatigue on legs, resulting in a shorter session for me.
You can draw your own theorical conclusions.
True is that massive concave with proper outline shape is totally the opposite of what you are saying.
have you ever tested a Mako?
You should.
I never believed in concave until i built a similar mako kiteboard with 2 cms of concave. I loved it. Great upwind, super fast, choppy killer, massive carving turns, no fatigue on legs, soft ride, nice in waves.
Why? Why?
A friend of mine, surfboard shaper, put a spoon and a flat surface under waterjet.
The spoon redirected the flow of water. The flat surface didnt in the same way.
"See this?", He told me. "Here is your answer"
