Dyneema Rigging

[Orkia]

As anyone used Dyneema rigging on a MacGregor? What is the impact of dynemma rigging on a trailer sailor?

[Jimmyt]

My cousin runs it on his Farrier trimaran. Says it's perfect for a trailer sailer. No kinks, easy to collect and secure for trailering. Only down side is paying for it.

I have some running back stays made from it. Also replaced my punch plate shroud adjusters with Dyneema lashings. It tends to creep when new. You may have to tighten the rigging adjustors several times so plan for that.

Do you mean standing rigging? I'd never do that since Dyneema chafes pretty easily and is susceptible to UV damage - neither of which apply to stainless steel.

That said, I've been considering replacing my lifelines with dyneema when I install cushions so that I don't have to swage new wire ones, and I incorporate it into purchase systems sometimes (I'm thinking about setting up a cascade on my vang using it). If you want to be really fancy you can get dyneema-core tapered sheets and halyards. It's an amazing material when used in the right application.

Personnaly I don't see the advantage in dyneema in rigging (ok, you save weight...). As soon you have your own crimp tool it is easy and cheap to replace and do repairs underway. It is easy to get wire rope anywhere... And it does not chafe so fast.

Whats the problem with trailering? I take the riggings, do some rounds, two lines, thats it.

Dyneema rigging would be easy to tie out of the way when taking the mast down for trailer. I have not priced it yet. I have replaced my lifelines. I am starting with that to see how it performs. So far, so good. It has a nicer feel if you are grabbing the lifelines to move about. It's easy to tighten using the existing hardware with slight modifications.

kurz - can you teach me to crimp it? how do I crimp the wire rope and what tool do I use? is there a you tube video that will teach me how to make the lines and where to get the wire and do it right so my mast does not fall down?

For Nicropress:

For hand swagging:

If using swags you need to make sure they are hand swag fittings and not mechanical swags.

Pretty simple, measure up, cut, press repeat.

Boat, crimping is actually quite simpel.

I think its worth having the all you need. You can fix so fast anything inc. the reeling etc.

Put 2 crimps on the wire
you make the loop
put in the thimble
Close the loop by pulling the first crimp close to the loop.
Put a grip plier under the crimp so the crimp cannot moove.
Do the first crimp press. The first crimp press has to be close the loo
do the next crimp. Middle crimp
do the third if enoug space (4mm cable).

3mm cable is much easier the 4mm.

But it is doable.

The tricky point is with the 4mm to have the very exact length when you need this including a loop/eye. But its doable.

Just buy wire and the tools.

Crimp a test eye/loop.

Then go for it...

All complete low tech!!!


I was very hapy having the tool when the cable broke of the trailer winsch. 5min - done.

same when the I had just 3 strans of the forestay - crimp it together til the new forestay arrive. Otherwise I could not raise the mast...

If I could buy a swager tool cheap I would get one. But they are expensive. $270 at Defender.
For a little more, I could buy an entire set of standing rigging for spare.

Maybe find a used swager on ebay.

You make a good point Russ - all I can say is that kurz sure would be a good guy to have on board out at sea when things go wrong.
(He seems to know how to fix anything on a MAC).

$60 at West Marine for the larger one that covers the sizes used on a Mac.

Not as elegant as the compound action crimpers, but will do the job.

[BOAT]

Well, I suppose Tom would be a good one to have on board too -

Maybe someday if I become a really rich billionaire guy I will buy a huge giant sailboat and i will pick my crew from people on this site.

Just to clarify that this tool from west marine is for nicropress and not swagging. You can get swagging tools just like this but not rated for standing rigging (rated for lifeline fittings) I have both the nicro and swag presses like these and they do work very well but are slow. The press I linked is rated for swagged fittings for standing rigging for $140.

Do the first crimp press. The first crimp press has to be close the loo
do the next crimp. Middle crimp
do the third if enoug space (4mm cable).

Check with the size and supplier of the fittings. Most small nicro fittings spec one to two crimps. More isn't always better and can weaken the fitting.
