The Pilot's Door

Each port has their own pilot(s) who bring each ship into dock. This is the pilot's door on the Africa Mercy.  A little speed boat will bring the pilot up to the ship, he'll climb in the door and then bring the ship into port.  Or, if the ship's leaving, this is the door the pilot will crawl out of as he jumps into the speed boat!  Ah, maritime life . . .
