Sometimes a picture says 1,000 words, so here's a photo of last night's mooring.
This is where the boat was tied up overnight, to a ring in the brick wall. The steel ring, which was immense, about 8 inches (20 cm) in diameter, had been cemented into the brick wall when originally built.
The ring was so large, it could be spotted from afar.
This is the first time the boat's been moored in the water along a wall with no way off.
