I have never seen a persuasive answer ... much less a consensus on any of these questions.

Why do we need an Olympic Slot for cat racing health?

How will co-opting an existing class for Olympic sailing impact the current class and its members?

Why and How do the Olympic Multihull matter to members in my local club?

The best answer that I have is the Olympic Multihull:
1) Develops and pushes the technology which trickles down to all cat classes.
2) Generates stars and hero's who inspire the young and old.
3) The Olympics makes catamarans relevant and important to the Yacht Club world. (cough cough)

I am not convinced that Olympics are the only way to achieve these ends... much less agree with some of them.

Anybody want to change my mind or make a better argument?
I tend to agree with Wouter that building a broad based pyramid of cat racing will serve us much better then building a thin column of olympic sailors that ISAF can use to keep sailing in front of the TV cameras.
