I think that to satisfy IOC criteria and get multis back into the Olympics, the event will have to be some sort of exhibition of cat sailing and not the pinnacle of our sport any more.
We will end up with some sort of short course/slalom easy spectating race on something like Hobie 16s. A bit like the snowboard-cross races at the winter olympics. you can watch a whole round of heats in an hour and understand what is going on.
