BEHOLD! It is the narrow boat "Valhalla", lately famous for the astounding incompetence of its new owners.
It enters the lock and the skipper stands on the roof of the boat.
I advise him that this is NOT a good idea (turbulence), especially as he is not wearing a life jacket.
"I will be fine", he said cheerily
"No, get off the roof and sit in the stern"
OK, he gets his foot caught in the carelessly abandone rope and SPLOSH
"HELP!"
My first water rescue
He managed to climb up a ladder (sans his mobile phone) and I warned him about the horrors of Weil's Disease
He was whimpering
