Is that an alvechurch boat or a guildford boathouse one? the chap stood in the lock looks like one of those lego men.
I dont think its getting more common, its just towpath telegraph getting faster with technology and maybe the news desk not having a great deal on that day. They also scan organisations news desks for anything which might fill space such as the MCA website and fings like that.
Very nearly happend to me a couple of years back although it wasnt the cill or the gates, it was that little lip where the hull meets the swim at the stern and the rubbing band at the bow.
going downhill one of the locks towards brentford, my mate was recovering from a brain tumour and was still a little slow with his reactions but was managing fine, I was at the helm and as i descended the boat as is its want occaisionlly drifts across the lock. Bow one side, stern the other. so diagonal across the lock. the Lip at the stern caught on some brickwork at the same time as the rubbing band...(i assume it was the band me being 62' away) caught on brickwork at the bow.
She started to list slowly as the lock emptied and suddenly realising what was happening i gave it full wellie in forward with the tiller away from the snagged side and was sceaming at me mate to drop the paddles. He bless him, turned slowly to look at me and cupped a hand to his ear. The poor sod hadnt a clue what was happening. I was now listing at the point of almost no return and was about to decamp when she suddenly dropped off the brickwork at the stern with a scraping clang and settled back down. I sat on the seat and sparked up. Gary, ambled over and asked 'what are you shouting about?' lol
We had been boating together on our various cruisers, NB's and barges for nearly 30 yrs and ive never come that close before, 1 moments lack of concentration. Sadly my mate is no longer here but like john that moment still is and still brings on the shudders
