Interesting theory. So you are not really climbing down to the deck, you are climbing up upside down.

So bats and flying foxes in the northern hemisphere don't sleep hanging upside down but standing up. Since they don't have anuses they must end up really full of s---.

It's an amazing world.

If you need any more reassurance measure the saddles on the toggles, mine on 8 mm wire rigging turn buckles are 5 mm x 40 mm.

The hardest part is catching the top mast steps with my hands as I fly past.

Thanks for those saddle measurements, interesting that they are the same for the 10 mm wire.

The shearing load might not control the proportions. Bearing loads induced by the clevis pins might be more critical.
My steel design handbook was one of my most referenced pieces of concentrated information I used for many years. Despite Bilkenny’s somewhat shrill comment, having a metal design handbook of sorts is very useful, much of the math is very simple and understandable.

Yes, it’s worth noting that the Hamma toggles have a greater radius around the clevis pins but taper away quite a bit between the pin holes and the toggle saddle.

I think I found the bit in The Rigger’s apprentice that billkny was referring too, where he documents chainplate options. It’s a bit light-weight but I am easily exceeding his recommendations by a number of magnitudes. Although I am unhappy about the weight aloft, I don’t feel like playing around with the safety factor by removing any metal.

Not worth it mate. Stow something down on top of the ballast and get rid of your wife's hair drier, iron, and all those extra pairs of shoes instead.

Oh, I got rid of the wife altogether. Huge savings on boat complexity right there.

Well, for a start, she wanted a second toilet.

Single life is so much simpler than that plumbing job.

Sounds like you had a lucky escape. Mine used to leave the tap running as she did at home whilst preparing food and empty the water tanks.

I confess, I’ve actually been encouraging my girlfriend to leave the taps running as I am trying to flush as much water through the new tanks as I can.

I concede I may regret this later on.

There's no doubt our biological urges get us into some terrible scrapes.

I solved my problem by removing the electric pressure pump and installing a hand pump. Might be something to keep in mind once the tanks are sweet.

Yes, there’s no getting past hand pumps for efficient water use.

Not gonna comment on the biological urges bit... down that path madness lies.
