I truly hope he does try out a cat, maybe it would be a good step forward with US Sailing.We'll see.
When he does show up, you should let him win.
But then wouldn't he consider himself a "master" and bloviate about how easily transferrable his vast lead-mine experience is to cats?
I mean, really, even someone with only a small fraction of sailing experience would see that not all mono techniques transfer to cats. Not the least of which is the speed which dictates a much different strategy on fleet races (like "connect the dots of pressure" vs. waiting for wind to catch you)
