There's an idea, I had been going into my duck and cover routine.
Whataya do if they just keep coming and you have to radically alter course to keep from getting cut in half?
Do what you have to do to avoid then protest, which is what you do whenever there is a blatant rules violation.
I've had many upwind/downwind, windward/leeward encounters and as soon the windward boat knew I was there they altered course and we both went about our business.
