When I did the Avon at the peak of the season there was no lockie or volunteer on duty anywhere above Tewkesbury all the way to Stratford.
And Wyre lock (diamond shaped) is difficult single-handed if you cannot board the boat at the bow or stern. The ladder is in the point of the angle. On my cruising launch, where I can only board midships, I had to haul the boat through.
Moored overnight at a lock below Evesham in the company of 2 narrowboats, we were exceedingly p*ssed off when a large floating restaurant came through at about 10pm (and returned much later), with floodlights glaring all around them while they were moored opposite us and set the lock. They ignored our protests and we only got them to desist by shining a 3million candlepower torch in the helmsman's eyes.
Some of the locks - gates and paddles - were very hard work.
Apart from that the Avon was delightful, especially the many anglers with their long poles across the river, who never grumbled when I went past. I'm sure those were cheery waves they gave me....... seriously.
Saw Blackrose but there was no sign of anyone at home.
