Would be nice to get the canal swimmable too.
And enough water in the Wien to even contemplate it :D

That being said, Donauinsel is still quite close to the center and I personally prefer the relative quietness and greenery around there to swimming in the canal.
Those pontoon ferry boats travel over 30 km/h on the Kanal.

According to their FAQ it is very much possible to swim in the canal under certains conditions that they mention as well.
