I bet that wasn't at 5pm or later!
I came past a week ago looking to moor and have dinner in the pub. After having to almost stop in the tunnel due to some numpty ahead of me thinking he could moor up in the entrance to the tunnel, I spent the next 20 minutes trickling past an endless line of moored boats for nearly a mile all the way up to the turn into Rugby Wharf.
I gave up and went through to Hillmorton Locks where the only space was on the 2 water points. Decided to not moor there even just for overnight and moved back round the bend and stopped there.
