Having said that if you look at the diagram then once you extend in order to place the weight somewhere else like on top of a boat for example the 10kg starts to look a lot more sensible
Depending on the height of the bank it is fairly likely the top of the boat will be between elbow and shoulder height for a normal canal boat on a normal canal. In which case my 12.75kg estimate of ideal weight works quite nicely for a man lifting.
Those diagrams don’t match my observations of most of the thunderboaters. Knuckle height should be much lower...
They are in my mouth being looked after by natural bacteria and a good diet. Apart from the one which a dentist buggered up with a filling when I was a teenager. That one has been hacked out by another dentist who almost killed me.
How does your being a hairy, smelly, rotten toothed, elderly ragamuffin help save the planet please ?
You obviously haven't seen my teeth
Dentists are a scam.
Then you've not found a good dentist. We go to one in Manchester, 40 ish Greek (god according to swmbo, ladies pm me for details, but she suspects he's gay quaysider pm me for details😂) he's great, gentle, did a great job on my broken molar and swmbos snapped crown just lately.

I don't need a dentist as my teeth are actually pretty good. It's dentist interference which caused the one and only problem I have ever had with teeth.
Firstly a filling when I was a teenager then it dropped out 15 years later then 5 years later a broken tooth then I got an extraction where he hit the blood vessel followed by loosing about a pint of blood or more and getting pneumonia unable to breathe almost dead with pleurisy eventually saved by the penicillin.
All this* because of a useless dentist who was putting fillings in kids with perfectly good teeth just so he could buy a bigger car.
Nothing to do with being afraid of dentists just dislike opportunistic scumbags with no morals.
Rant over. *Plus doctors are a waste of time (giggle)
