The best way to handle the man overboard situation is to prevent man overboard from happening through use of harnesses and strong fastening points or jack lines, which run from bow to stern, or stern to stern via the bow, and the like. The saying,
Keep one hand for yourself, reminds the sailor that his safety is his personal responsibility. Risky behavior, ignorance, lack of preparation, lack of anticipation, or stupidity are not rewarded. See bottom of this page for a link to an article on the US SAILING site about how to remain on board.
