There is exactly 0% chance he is single handing that boat and I doubt he has in years, if at all. If you watch the video, he walks down the pier like a little old lady (I'm sure I will too at his age) and needs to steady himself by holding on to someone else while he steps aboard. The crew may not be visible in photos/video, but they're there.
