Well, the document, as written, basically reinforces JJ's point. It lists some gear and equipement that would be good to have aboard, and reiterates that the sailors are ultimately responsible for putting themselves in harms way, but basically says nothing about the OA role.
My understanding is that this committee (and charter to write this document) came about specifically at the request of yacht clubs that were being asked to potentially host cat/tri regattas for the first time.
I don't see a whole lot in this draft that would help such a club decide what their responsibilites are (in terms of wind/wave guidelines, being rescue-capable, etc.).
