If you let yourself drift slowly over the still water of the canals of Utrecht, you will see how time merges with the reflection of centuries-old facades. The quays seem to whisper, wharf cellars tell secrets from times gone by, and bridges bend subtly over the water as if they want to guide the tour boats on their eternal journey. But it is precisely in this enchanting encounter of present and past that a strange feeling arises, a subtle dissonance: why are tour boats not round? Because while the name 'tour boat' playfully curls around our tongue and tempts us to expect soft, flowing circles, a rectangular colossus glides past again and again, squeezing its way through curves with laborious angularity. The word 'tour boat' conjures up an image of effortless elegance, a soft dance that repeats itself endlessly; no word so friendly, so clear in its simplicity. Yet we seem to have collectively forgotten that the name has long since revealed what the ideal shape should be: round.
