I believe that virtually ALL riders would be prepared for racing on the Saturday as this has always been a possibility and also has actually happened in the past and since they allow time to 'recover' from their post-racing celebrations, I can't imagine many would be hot-footing it onto the boats on Friday evening. Also, most riders would be prepared to re-arrange for a later sailing rather than miss the chance to race if it were delayed to the Saturday!
I know personally of a bunch of marshalls who were NOT asked if they would be available on the Saturday. There may even have been Manx residents who had not previously volunteered but would have come forward on their day off from work, had they known about the possibility of a cancelled race? Could it be that the marshals are being 'used' as an excuse when in fact there was no intention of roads being closed on the Saturday, for some reason? Or even that the weather forecast was also poor for the Saturday and so this wasn't considered as an option? (Benefit of the doubt.)
I understand that the MCN is claiming that the Senior didn't happen because of a lack of marshals. This is hardly true when in fact the case was that the weather was responsible, surely?!
Just another opinion.
