My only MOB exercise has been to retrieve hats blown off.
As for gybing, not something I do if going-about is an option. But sailing on the run (soldiers wind) always an eye on the burgee just in case an unplanned gybe feels like it's going to happen. Then sheet in asap to center.
As for those who are missing something, yes, sailing has far more appeal than flying in today's environment. And you can eat sleep and drink on a boat.
