Every now again when surfing I wonder if I look like a surfer or a guy doing a p@@

In theory, you drop down the wave and as you approach the bottom turn you bend your knees and spring back up to launch the board back up the wave whilst leaning into the turn. When you see a real surfer do it it is smooth, effortless, and they get a lot of extra speed. And they look like a surfer.

Some people bend their knees and they don't spring back up. Some people crouch and don't look as if they could spring back up. And some people look like they are laying an egg.

Sometimes I turn the board simply because I place my weight such that the board turns - but my weight is pretty much straight up and down - I am steering the board. Othertimes I properly lean forward and out, perhaps with a lot of weight on my paddle, and it feels real. But you better be very familiar with the board and have your feet in the right place or you will put too much weight out there or not enough...

I am an engineer. I need a written procedure for how to do this. Is my back straight up-down or leaning forward? Where should my bum be? What should the angles be between my shins, thighs and torso? Am I squatting, bending, coiling, crouching, or what?

Colas and STC, I expect stick figure diagrams that include the position of the surfer's centre of gravity

If you watch this video you can see the difference between the coaches and the learners. But I am having trouble pinpointing the exact process to make this work...
