Boat control.........especially when running mixed gear really comes into play. Example if only running 2 dips, you can turn as sharp as you want to almost....running 2 on side, or 3 or 4, now turning too sharp makes a mess. Certain big boards pull harder than other, and then if you have in lines they can pull even less. So knowing how much room one needs to turn, not get tangled becomes real important especially if it's a busy spot with lots of ppl in the same area.

Plus certain gear of the same runs different on every boat....what I can do as first mate on an eye hunter 30 ft sport craft, I can't do exactly the same way in my personal 19fter.
