So, then, could you point to your explanation(s) where you speciified that your reference to Dyneema was regarding its use as a rode, whereas the reference to Vectran & Kevlar was regarding its use as a sleeve?
Any one of the numerous times that clarification was cited prior to the sentence/post I was responding to should suffice...
I'm sorry I can't quote whole posts here, because apparently you want me to quote the entire thread, and then explain things to you once again.
But here goes a few (bold=my emphasis
Vectran sleeve for anchor rode
For the follow parts, click on them to see where in the thread they are:
Hi, I just had a thought, being relatively satisfied with rope in my neighbourhood, only being nervous about having the rope cut by something.
What about a leaded anchor rode (as in "rope"), but having the lower half covered in Vectran, so as to protect against cuts? I mean, obviously, Dyneema won't work as it's not springy at all and is surprisingly easily cut, but Vectran or Kevlar (as used in stab proof vests) seems to be a completely different thing.
I'm not worried about the price of the sleeve (obviously), but I don't want to waste time ordering and installing the stuff (plus the splicing needed afterwards) only to find it was a waste of time and effort
Particularly about the cutting resistance which is the whole point, and the weight of the boat I mention.
If you think about it, I'm asking for something easier for the hands than chain, weighted like chain, and with a cut resistance, if not equal to, then closer to chain than polyester or nylon.
It's an effort to think out of the box to gain most of the benefits of chain but without the drawbacks of chain, by keeping some of the good things about rope. Getting a weighted rode (as in inlaid lead), with a cut resistant outer is something that in theory ought to possible with something more modern than nylon or polyester. Or hemp, like in the "good old days" of 1963.
Sigh, once again, go read the opening post. I was talking about a sleeve on the outside of the actual rope. A sleeve I would myself put over, making it lose, so the anchor rope within would continue to be able to give as it should. Hell, the thread title even uses the word "sleeve".
I was thinking of checking the give in the core line, and then make the sheeve a given length (depending on how long the protective sheeve will need to be - could be 60 feet, for example), and then attach the end of which, 25 percent lower down on the core - in essense "pushing" it down a bit so it doesn't influence the core rope.
I was thinking leaded line from Liros to hold down the shank, but now when I think about it, I could test the cut and abrassion resistance by attaching a bigger sleeve around a piece of chain just to test it.
The boat will have a (carbon) bowsprit, but in an oldstyle, with bobstay, whisker stays and so on, so I will have to use a bridle or a snubber even with chain. I don't think I want the actual anchor rope to be high mod, although it would save some weight. There's a hole in the stem where the bobstay is fastened (it's actually fastened with dyneema), which ought to be big enough to be able to attach the snubber to. And it's a real low boat (it has no cabin or anything), so I will be able to reach that from lying on the foredeck.
If you notice here, I'm actually mentioning being able to lie down on the foredeck for a reason. But, oh no, that must be to "show off" according to you.
You want more posts to show how little you have understood in this thread? Okay, then:
Thanks, but I'm not talking Dyneema for the sleeve, I'm talking Vectran, which has a much higher cut resistence and a somewhat higher abrasion resistance. And it only needs to be "loose" around it, not super tight, and being pushed "down" towards the anchor, it will be at the slimmest (but still big enough) when the line is completely taught (as in no stretch left whatsoever).
I will look into the Dacron sleeves. I don't think I'm ready for a through-and-through Dyneema rope. Hell, just making something grip it at the snubber end will be problematic.
As for plastic making poor abrasion sleeves, I can only say that leather or, indeed, kevlar makes for great abrasion sleeves in general.
I will definately look into every sleeve I can think of, but I think Pdq had it right when he suggested I should look to the multihull crowd for experiences in this regard.
(yes, it truly is a fin keeled dinghy, lol) [...]
Yup, hence I was looking at vectran and any other ideas such as the dacron suggestion.
It will be a loose sleeve, only stitched a little at both ends to stop it sliding off.
I never said it was springy, I was saying the actual anchor rope being springy. Think of a elasticated tether. The outer sleeve is longer than the relaxed state of the inner springy bit. In my use, however, the inner "elastic" will be the actual anchor rope, and the outer sleeve will be longer, relatively speaking, to the inner, so it will not at any point be taking any weight.
I want to match the stretch because I want to go a bit oversize, so that I can 1) minimise heat between sleeve and the rope, and 2), because I don't want the sleeve to influence the stretch of the actual rope.

I will probably end up having a bit of chain, at least as a back up rode. I'm still not too confident about having any part of the stuff being high modulus, though. But having "stuff" in three separate parts just might be the way to go. Couple this with PDQs suggestion of long nylon snubbers and I think we might be on to somethin.
Yes, I was thinking of stitching the sleeve with only a few stitches at both ends, so it could be pulled up and down easily with a few snips and just as easily stitched back - mostly because it would be an easy way to inspect the underlying rope for chafe. Perhaps it would be even easier to tape it, he he.
I'm still contemplating that sleeve over the chain idea. It would certainly make it easier to handle on deck by hand.
Regardless of anything else, I will be using snubber(s), simply because the boat has a bowsprit and bobstay, so I figure it's needed.[/b]
Notice how the bowsprit and bobstay is a relevant part of this? But to you I'm merely "showing off", right.
Thanks, I do think I might end up having a covered piece of chain at the bottom, although I will do my utmost to find another solution, even if that means more inspection. I also think, that regardless what gear I end up with, I think a piece of chain to be attached will be the prudent thing to do, especially if leaving the boat for a couple of days. I would just prefer to not use it on a daily basis. Especially not a rough, uncovered chain.
See, it would have been much easier if you had been able to comprehend the thread title from the get-go, instead of trying to accuse me of "showing off" when I mention things that are relevant to the topic at hand, and when I showed you how to do a google search and find a type of product.
Also, it would have been much easier if you had actually reread the thread, instead of having me basically repost the entire thread so it could be spoonfed to you in bite sizes suitable to you.
My apologies for eliciting so many "Sighs" from you... Dealing with slow learners like me must be the reason you're "always tired", eh?
Yes, I guess that must be the reason, not impatience with people insisting on misconstruing what is said.
