I can't imagine that being a very quick thing to do.

Clearly demolition is one of the things to consider in this scenario, and is at least as realistic as the million-luftballons. It would also make for some fun conversation.
A smaller less stuck ship or barge you don't care very much about full of explosives.
And you don't need to destroy the whole thing, just shred and distribute the part that's in the canal enough that it's no longer an impediment to navigation. Sure you might be left with 30 big chunks but 30 big chunks can be picked up with conventional marine construction equipment. If the bulbous bow is still buried in the sand then whatever, you don't care.
We're talking about a Mont-Blanc sized explosion here. Definitively messy but with modern engineering I think you could whip up a directed blast that ensures the task is accomplished without unnecessarily digging a hole or some other dumb side effect.
