I have sailed my H16 (before I sold it) solo numerous times. I am big enough to be able to right it solo as well so I wasn't worried about that. To handle the eventuality of a solo MOB I always had weather helm on my boat. This way, if I was unable to sail for any reason the boat would head up an into irons in light wind or capsize in strong winds. Either way I could swim to the boat. I even jumped off just to see how far it would go on it's own. It was a bit of a swim but manageable.
