Matt, are you out there?

I don't know the specific reason, but proof of insurance is collected and copies maintained at Hobie NAs. We require it in a lot of Hobie SIs for "lower" events, but it is rarely (if ever) verified. I believe that we use the same regatta insurance for these events as all points regattas, etc.

If I had to guess (which I hate doing), I would say it's enforced at the international events (NAs) to be sure that the foreign guests at these events have coverage that is appropriate for the venue (which is not always in the US).
