According to the official Gilligan's Island backstory, why does the Skipper keep Gilligan around even though he's a bumbling fool?

As the story goes, during World War II, Skipper and Gilligan served on a destroyer together in the Navy. When a depth charge got loose and rolled down the deck, it almost crushed Skipper. But Gilligan pushed him out of the way and they formed a lifelong bond.
