That doesn't sound very good....
wonder if it's the same chap throw, the lad I refer to was well built physically, and clearly had been working hard at something before coming to be alongside the canal, maybe a marine, he was no grunt though, very intelligent and well spoken (definitely a trace of northern in his voice) and maybe a officer?
when we arrived at the top lock the gate was open, and he was asleep on the balance beam in the sunshine windlass tucked in over his shoulder, we steered into the lock, he swung his legs down and greeted us, I joked about paying him to do the locks and hey presto we gained a paid crewman.
honestly though he did all the work, preparing the locks ahead as well most of the time and we flew down the locks with ease and he must have known what he was doing around boats, at the bottom of the locks I asked him how much and he just said what ever you think it was worth sir, I gave him £30 and he gave me £10 back. The last I saw of him that day was him napping on the balance beam in the sunshine again awaiting the next customer I guess.
my daughter seems to think his name was maybe Jon? And he had come from Plymouth? She did know that he had been a boy on the canal and wanted to build a tug to work around the system.
id be very grateful to know if anyone remembers him or knows him, a work tip he gave to my daughter has led to some very good years for my family, and it would be nice let him know how grateful we all are.
