Oh, and their river-reading is pants. It wasn't a "whirlpool", it was an eddy. And they weren't "trapped in a whirlpool", they were sat on the eddy-line! If you're going to sit there then that's asking for trouble, but a couple of paddle-strokes would have moved them into the eddy where they could have safely sat and mended the outboard motor to their hearts' content.

It was, although they glossed over the facts that (a) they set up a load of nets to catch birds and flying mammals, and (b) if a bat like that is trapped somewhere and unable to feed for an hour or so, it will become hypoglycaemic. They simply presented it as an "injured" bat, as if they were helping it.
