A boat of swords being ferried across a river with a woman as passenger. The classic Rider-Waite meaning is that one is leaving difficulties behind. A trip or change of scene may be the answer to restoring balance here. But there is more to it than this. In relation to the mind, ideas and words of the sword suit, this is also about finding a solutions to math problems and brain twisters, not just troubles.
The ferryman is part of the give/take here. He has a fare thanks to this passenger, and his passenger has a way across the river. What he symbolizes is help in finding answers or solutions to problems. He might be a reference book or website, or perhaps just someone who will listen while you talk and work things out in your head. He rows you in the right direction, away from confusion and mental turmoil to smooth, thoughtful waters. Waters clear and clam that you can, in fact, see the other shore, the answer, in sight!
There it is, a way to make your idea, your argument, your formula work smoothly, perfectly, beautifully. I sometimes call this the "Eureka" card in that it has that feeling of a scientist catching sight of a solution.
The reader should warn the querent that they haven't arrived at that other shore yet. There may be a good deal to work out, but this is a break-through moment where the mind is working once again. And whoever, or whatever helped you get there also feels mentally rewarded.
Note that this card can also be about trips by boat.
