What is it about 'summer' boaters? Why are they in such a hurry?
One such boater actually tried to enter a lock on the Caen Hill flight without first opening the gate and knocked it off its hinges! See Narrowboatworld.
Needless to say the Kennet & Avon canal is now closed at Devises. I do hope that the boater in question is fined a suitable amount for preventing other boaters navigating through those locks, up or down.
