WOW, thats a really smart reply there. Being an engineer for 25yrs, I would assume you have a better come back. Sail more post less.

Let's get back to the original post, okay??

The system does not work. The bungie will pull the trapeze ring out of the hook because there is no take up tension. You won't find any national or world multihull crew sailing with that rig. The pic of the Marstrom system shows clearly a take up bungie system. As long as the ring is pulling up into the hook, it will work!

Been there, got the t-shirt, chewed the gum on this one!

Well, I've been patiently waiting for someone to bring up what I have found from experience as the weak link in this adjustable system. Your digression into the bungee tension aspects of the setup certainly was entertaining, but the reason I gave up on the adjustable system was the v-jam cleat surrendering at the most unexpected moment. Boom ... you teabag when you least can afford it. Stick with a single length system and let the skipper adjust (raise a couple of inches) the heel angle of the boat to keep you out of the waves.
Anybody else have this experience with the cleat?

Yes, but we have found that it depends a bit on the line used. The wrong line will definately dump you into the drink, whereas the right line works just fine.

Ditto.

Of course I'm not world class sailor so anything I say is rubbish according to some people. However, I have a knot in the adjustable line that blocks the system from giving more way than to the lowest position I ever want to be. So I won't fall in the drink and I can always find to lowest position quickly. I only use the adjustability to hang higher to come and go out or to clear the waves or hang higher than my crew so I can see what is going on ahead.

Use a line with a soft outer core

Of course we also have a knot which stops any sudden downward acceleration if the line slips (but it never slip unless the wrong line is used)

If the line is to long, or you are sailing relatively flat, you might become wet anyway of the line slips (which it doesnt do if it is correctly sized and relatively soft). But you will not be dropped completely into the water.
We have tied the knot so it also offer a loop you can slip your hand into, to get a better grip when raising yourself one-handed.

There is no problem in letting the whole cleat/ring system be pulled upwards by a bungee, so it doesn't slip out of your trapeeze hook.

Please define "outer core."
Seems like an oxymoron to me. I can see a "soft shell/cover."???
