The answer he gave was "some say not a lot but - I'm in charge!"
I like a Captain who thinks like that!
Me too. It shows he has confidence in his officers and crew to do their duties without the Captain micro-managing things. To me a good Captain provides oversight and coaching and leaves the hands-on stuff to the crew, except in rare situations.
In the U.S. Navy, the day-to-day operation of the ship was the job of the XO (Executive Officer or second-in-command). I believe the same holds true with most cruise lines, where the Staff Captain is the XO.
