The ZO debate affects only the upper performance echelon of the sport. Those of us still struggling at longer line lengths do not notice the pull (at least me). While the very competitive tournament community has a real problem with the shift in technology and programming, most of the rest of us cannot tell the difference. The tournament slalom boat market is very small, and I would guess that most of the boats are NOT sold to the people in the ZO debate. Of the 6 most recent ski boats sold that I am aware of, only one was sold to a person that has ever competed in a Regionals or Nationals (well, three were sold to show skiers who have their own nationals). The promo boats are sold to upper echelon tournament skiers, but I would guess that only 50% or so go to them. The rest are picked up by more recreational skiers. The rules that call for a .5 max variation have never been complied with. I don't think that any boat can satisify that requirement with a big skier behind the boat. Water, being a fluid media, just does not allow for that kind to tolerance. As a sport, we have painted ourselves into a corner trying to be "fair" to all skiers. Until we have an electrically driven rail system, there are going to be difference and tolerances. We cannot get away from it. Does it really make that much of an impact? I argue not. Yes, it is frustrating to have your performace impacted by variations and tolerances. In the world of snow skiing and snowboarding, the time of the day you have your run can have a profound impact on your score. Additionally, the course is never set up the same way every time. It is always different - that is accepted and the skiers and boarders adapt. There has been several game changing innovations in skiing: ropes, handles, adjustible fins, wings, plate bindings, hard shells, liners, CNC props, fuel injection, tracking fins, metric system, etc. It seems to me that the previous innovations had one major difference from ZO - the cost and pace of implemtation. Yes, it is not the preferred way to implement the changes. However, if anyone was invested in a company with the patent protection and they failed to maximize it, you would scream as a shareholder to replace the management for a team that would increase the payback on your investment. Ideal for the sport and your performance? No. Our sport is expensive. It is also very fussy with lots of picky rules that are the souce of endless arguements. It reminds me of the young boys on the baseball diamond arguing - until the ball gets taken home in a huff. The real question is how to we leverage this into a positive? ZO is a lot easier to use and to drive. ZO is also a better pull for wakeboarders. Maybe our wives will like driving the boat more with easier speed control.
