I suspect that this is probably true...
Skiers who don't ski tournaments care about skiing for fun
Class F skiers care the above plus local event competitive participation
Class C skiers care about the above plus AWSA regional/national rankings
Class ELR skiers care about all of the above and national or IWSF rankings
The one thing that I didn't think worked for INT was their concept of "nationals." Amateur levels compete locally. Class F events are for the locals. The whole grass roots concept is that the local people are given a means to participate locally without the barriers that are appropriate and necessary for regional/national competitions. Thus, the additional officiating, head tax, etc. are all elements of complexity and cost that are appropriate or necessary at a higher level of event.
The opportunity is to make the local amateur structure/rules as lean as possible. Minimal officiating, basic liability, relaxed boat approval spec, etc.
Consider if, for Class F, you use any formerly approved towboat, with an assistant rated driver and a single assistant judge in the boat, scores documented on paper, local winners/awards at the end of the event, etc. The key is to have the cheapest liability solution for minimal cost to hosts/participants. If we didn't have liability and litigation fears, then anyone could/would host their own "tournament" at the local lake for the local skiers using their own local rules, etc. It would be fun...
Heck, I'd like to see class C simplify a bit, too. But that is a different conversation...
