The Six of Swords is a card of moving on. The people on the boat are on a journey, heading towards better things. The Six of Swords is also a card of travel, and may indicate a trip or a vacation of some sort. Because the image depicts people crossing a body of water, it could imply that the trip taken will be one by, or close to the water.  If this card appears reversed in a reading, it infers that things will stay as they are. There is no forward motion at this time.
