Strong enough for 1 to 1? The pro setup without pro strength

- Over the last 5-10 years 1:1 trapeze adjusters have taken over the professional 49er and Nacra fleets.
But why are the pro's using them? And are mere mortal amateur sailors strong enough to use them too?

I wish I had done this when I was in C420s, I hated the massive tail and frequently had to take 2 stabs at the tail to get down all the way
OK well noted, thanks
Coś pięknego❤
we use this as well, great video! But U should not wrap ur hand in your trapeze line while adjusting. If u cant take urself up or the cleat slips or uncleats u can get stuck and break ur hand or worse!
Definitely! I rarely do it on the water, but the clip hanging from the balcony was thinner rope on spare wires and my hands were frozen!
Nice picnic table boat setup, lol
😁
Hey, can you tell me, what type of harness your wear in the video, looking form them quite a long time.. Thanks!
It's the Shock original here www.shocksailing.com/category-harnesses.html
How does this keep upward tension on the ring when you dont have weight on it? IE where does the bungie attach
The bungee goes from the hoop to a deck eye and then passes over the boat to the equivalent fitting and trapeze on the otherside
Moving to this set up on my Musto Skiff. What's the best way to attach the elastic to the hook?
We tend to put a bobble on the end. The push a loop of elastic through the eye. Like you might with a halyard
@@MozzySails Cheers - sounds like a neat solution
What do you suggest using for the adjustment splices in the trap line itself
I use a 'continuous splice'. It's covered in my 'bimble or bollocks' video at around 5 minutes 30: th-cam.com/video/7nnbg6nWZd8/w-d-xo.html
It's quicker to adjust than a standard adjustable splice and can even be adjusted whilst on the trapeze
where to buy?? halyard and arne 🇺🇸
Nice one, and all good points. Unfortunately, at 01:11 you got the physics wrong. 1 to 1 is actually 1 to 1. The upper block is fixed, and it only reverses the direction. No longer travel of the rope and therefore, no purchase. Golden rule of mechanics. However Kudos to you for effortlessly pulling twice the weight you think you do. ;-)
The top block is fixed, but because the load being moved is yourself, then it's a 2:1. Everyone kilo you pull is one less kilo weighting your hook.
@@MozzySails You mean not just the "push up the hip" technique? You say that actually the top block becomes a moving block because the load being moved is yourself? I try to see your point, not sure yet.
@@nauticfilms normally, you can count the number of lines coming out of the moving block as a very simple way of calculating purchase. But it get confusing when the work is being done from within the system. Movement is then relative. Is the sailor lifting himself, or is he pulling the boat down?
To put it another way...there is 70kg on the single trapeze wire. So there must be 70kg split either side of the block. I can't be pulling 70kg down on the tail, and have 70kg on the hook, as they would make 140kg... and I dont weigh 140kg!
@@MozzySails Thank you for your argument. I am still trying to get my head around it. Can we agree on this: www.dropbox.com/s/6w88sqhyam4ekcj/block-and-tackle.png?dl=0
If so, what difference does it make from where the pulling force is coming from
?
Great channel, keep the good videos coming. Unfortunately you got your physics wrong on this one.
In what way?
What harness is that?

@@MozzySails Much appreciated, thx!
You're entire explanation is incorrect unfortunately, 1:1 means you're lifting the full weight , all the block does is reverse the direction of the rope
Every kilo of tension you pull on the adjuster, is one less kilo of weight that's on the hook. For the rope to move, there must be more tension on the adjuster rope being pulled by your hand, than is going through the hook. That means just over half your weight on the line you are pulling and half your weight going through the hook. So the force you have to put in is only just over half you're weight... hence 2:1.
