The captain or officer is very proud of his ship and is explaining in detail, every aspect pertaining to the passengers questions.  Before this, the captain was greeting other passengers, and the passenger shown in the picture was walking onto the ship with his luggage and maybe his family.  Both men are very excited to embark on this journey.  The passenger is more curious as to what this trip will be like, whereas the captain or officer is excited because he knows what it will be like.  What will happen next is that the passenger will be shown to his room by a crew member and the captain or officer will continue to greet new passengers until it is time to embark on their voyage.
