Mechanics are crucial, but in the end, even the most technical approach to the course will be fruitless if you interrupt your rhythm.
The problem is this: when you are faced with a mistake in the course, (wheelie-turn, tip-grab) your natural inclination is to increase your lean behind the boat in an attempt to arrive at the next buoy as early as your approached the previous. The problem is, an increase in leverage behind the boat is going to cause misalignment as you leave the second wake (the straight line formed from your rear ankle, trailing hip, handle and trailing shoulder will be more difficult to maintain.) In other words, you will likely get separated causing you to run a straight line into the turn. Regardless of your turn, it is important to keep your rhythm and intensity the same from your first pull-out to you your final turn.
1. The ideal intensity will leave you feeling balanced over your attack edge. Not cutting.
2. If you feel a spike and subsequent release in pressure, you know you are leveraging too hard against the boat.
3. By thinking in terms of rhythm, you will be far less likely to pull too hard, or too long, regardless of how early or late you may be in the course.
4. Early or late, remember, the fastest route from A to B is a straight line. Therefore, simply relax, align, and keep your rhythm consistent, even after a botched turn.
