Rob and I were the only passengers on this trip and without hanging around Capt Craig starting winching out the cable so the end of the ferry would swing out and then have the river current assist it to the bank on the other side, 700ft away.
Another link with more information and history is here.
I also found a YouTube video from 2011.
We headed back to Rob's house and interrupted the peace of Miss Marbles who promptly fled as I walked through the door.
I'd brought down a shotgun to try out so we trudged outside and set up a water bottle target.
