First of all, TWBC is AMAZING and being able to watch waterskiing on TV multiple weekends this year has been just unbelievable.
No matter what skier is skiing and what line they are skiing, there are 3 things they all do:
Their shoulders never rotate inward toward the boat in any turn. In other words they turn with their lower body ONLY. Their shoulders never rotate enough to cross a plane 90 degrees to the boat wake.
They never hinge at the hips.
They all have a very high gate and turn in from that high point.
No matter what their style is, all of the above is very consistent skier to skier. Keeping it simple and focusing on the basics is the key to progressing. I’d ask yourself if you’re doing all 3 things next time you’re in the slalom course. Thoughts?
