Have you written a letter of complaint to Bw Yorkshire Navigations ?
As you didn't arrive at Keadby lock the alarm should have been raised and someone should have come looking for you .
That is why the tidal locks are not boater operated, so that boats are logged on and off the tideway .
If a boat does not arrive there must be a problem .
Last year I spent a night on the tidal side of Naburn lock as the keeper had logged off for the day (18.30) he had been told to expect me by Keadby who contacted me an hour into my trip to confirm this.
If anything had gone wrong I could have been washed out to sea (Naburns keeper couldn't give a toss !)
