Look at the photo, it's hard to describe that as anything but a barrel: https://dynaimage.cdn.cnn.com/cnn/q_auto,w_634,c_fill,g_auto...

In particular, it lacks any conventional boat elements like a method of propulsion or steering.

He is clearly milking the label for all it's worth though, the GPS tracker ID was "diogene" (French for Diogenes of Greek philosopher living in a barrel fame) and his sponsors included several manufacturers of wine barrels (https://www.boutes.com/), who apparently also helped build the thing.

In that case I am slightly disappointed that the voyage was undertaken without the barrel also containing a pack of feral dogs. The resulting footage would be worth it if nothing else.

The plan shows this had a keel though.

What does that do?

Maybe allow choice of current, like where it forks?
