I seasoned race care driver, skier, and waterski industry professional basically said you need to “look where you want to be” to sum it up. Everything slows down when you do. No diff then driving your family car around the corner. If turning, your eyes will look well past the turn and the focus is where you want the car to be. Same in a straight line or curve.
I ski best when my eyes find the next ball out in front of the boat. Just got done skiing and was working on this.
Long ago a tried a baseball cap and pulled it down low. Forces the head up to keep the eyes at least as high if not higher then the horizon.
