Summary: Leaning on an edge of a surfboard will cause it to "carve" in that direction. But why?
I was a little bummed there is not a Marine Engineering section, but there is an Aeronautical Engineering section.
The term carving describes turning on a surfboard. It is a roll + pitch or yaw or a combination of the two.
My question is what forces cause it? It is different from a boat because there is no rudder. There are fins, but these resist turning don't create it. A finless surfboard (Alaia Paipo) turns easier than one with fins. Searching for an answer on google was somewhere between comical and frustrating.
My intuition tells me that when CG shifts off centerline the board heels and the rocker of the hull bottom causes the board to turn with it, but a flat board will act the same way.
I assume the chine generates more drag on the heel side and maybe this plays a part. I know from experience that a board with soft chines doesn't turn well.
Thanks for anyone's input.
