No, it didn't make all that much more sense than you are imagining.
Also, the boat was a subway train - I waited for it on what was basically a subway platform extended over the surface of an underground lake. That part was actually pretty cool in a dream logic sort of way.
I'm adding this to the pile of "things I have dreamed that really seem like they should have been nightmares but were actually just funny". I mean, a boat, you guys. XDDD
