If the boat merely takes them where they want, it's too easy. They got that early, but there was a reason for those journeys to be simple, and besides, the plot is building
And the first thing that came to mind was getting an object to let them control it. That turned into a character sardonically saying that they need to get something to move the boat because they need to get something to get a third thing. . . he doesn't have the term "fetch quest" but they all recognize the concept.
I think they are going to cast spells to do it. Improvising. Which gets another character commenting about how they are reinventing spells that sailors use. . . .
