Hi Alan,
The Yacht Station was there long before the Wetherspoons and night clubs etc. I am sure someone will have a pic of it when it use to be chocablock double moored most if not all its length. That length of mooring now, has been reduced, and has been made more secure too, with coded gates.
I do like your idea sort of, moorings being near Carrow Road and Norwich FC, or beyond Bishopsgate, but, just like the YS it will have its ejits that think its fun to undo mooring ropes. Personaly, I always ring rope back onto the boat and drop the mudweight.
Just read Matt's remark and agree some may panic there. (Bishopsgate Bridge)
Iain.
