Sime minor points:

Per RRS, the RC runs races as directed by the OA. So, The OA has final call on when too much is too much.

Of course, per the RRS rule for abandoning, racing may be abandoned for reasons including fairness and safety. The PRO usually is the one to make this call.

In a perfect world, the PRO and OA work seamlessly together, making this a non-issue. The problems come in when the PRO has too much ego, or the OA didn't bother to procure enough resources to run a safe event.

One thing that is painfully obvious here is the lean toward A-Cat and spinnaker (read, fragile/overpowered) boat racing, in typical North American (read, light) conditions.

Go to a Hobie 16 Worlds and try to postpone because it's blowing 28, and you'll probably be shot...
