The course race officers (there are six course circles here) do not have the authority to call off racing. They must receive authorization from the Principal Race Officer (Ricardo Navarro - a Brazilian, who started out racing Hobie 14s).
I saw the PRO boat pull up behind our signal boat in late afternoon, so I'm sure there was some conversation about the conditions. Peter van Muyden (the course RO), is very experienced (he runs the N17s at most of the ISAF world sailing cups).
The top guys probably would have bitched if it was blown off.
