The cross-harbour ferry "ties up" to the quay at either side by dropping a hoop over a short post fitted to the edge. The hoop is lifted and dropped remotely, by a line running to the little cabin aft. The passenger ramp is also remotely operated—you can see the little block and tackle arrangement running to a pulley with another line back to the cabin.

The boat's crewed by a single person, and they're usually accurate enough with their aim and their remote controls that they don't need to leave the cabin at all during their back-and-forth trips from here, the harbour inlet, to the SS Great Britain steps on the other side. These days they've stopped taking coins, and avoid corona cooties by staying behind their cabin window and holding up a card reader to take your £1.20.

Bristol has a long tradition of ferries. The Rownham Ferry near me was operating in the 12th century, and I was reading about the planned temporary closure of Gaol Ferry Bridge this morning, which fairly obviously is the bridge that replaced the ferry that used to run between Bedminster and the New Gaol.

Interesting how "new" is quite a stretchy word. The "New" Gaol was demolished in 1898, and of course the bridge spans the "New" Cut, the diverted section of river that was completed in 1809...
