Pot, kettle black comes to mind. There was more than enough space on the lock landing for you to use it. I came past there whilst they were moored there and stopped off for an hour. This is also a lock that is hardly ever used as most folk use other flights at factory or smethwick. This is why it is heavily silted up and difficult to manoeuvre.
But hey ho, carry on with your lovely summer hobby of racing around the BCN and moaning about anyone who has the audacity to be in your way. Hopefully you have mothballed your boat for the winter so those of us who cruise the BCN and surrounding canals all year round can get on in peace.
