Source for Cruising Dyneema

Could you use the Technora Grip Prrotect to cover a sewn/whipped repair of your current halyard? The dyneema core is doing all the work, no? I’ll admit I have short arms and long pockets, so worth a try perhaps to save buying a very costly 50 metre halyard?

I did all the reefing lines this winter in 8mm cruising dyneema sourced from Rope Company | UK's No1 Rope Company. Sailing, Boat rope, Yacht Rope, Garden Decking Rope, Dyneema ropes - Lowest Prices for Rope in the UK. Sailing, Yacht Rope, Dyneema, Garden and decking Rope by the metre
Joe was excellent and did the splicing work (difficult with cruising dyneema) as requested and I think he is the cheapest around.

Interesting. Their racing halyard looks great but again over £800.
The cruising dyneema could be an option as substantially cheaper than the Liros at just under £300.
But it looks very similar to what I bought a few years back for the jib furler which didn’t seem as robust cover as the Liros, so didn’t fit but moved to the traveller which has much use.
Worth considering.
 
Could you splice in a new section?

Wire to rope splices are strong enough for halyards and a joining splice through stitched (and away from the clutch gripping areas for reefing) should work if the rest of the rope is good.

I would redo the sail end splice every year so that the clutch damage is moved around.

That’s actually a very good point. Sew in the existing cover either side of the break and then sew a fairly long bit of the technora over the join.
 
this is off on a bit of a tangent, however we recently had to replace our 2:1 mainhalyard (60m) due to chaff (now have 2 pieces of 30m 12mm dyneema to use elsewhere). new rope is International Rope Braid “Falcon Braid” Construction 12-strand Urethane Coated UHMWPE Core w/ 24-plait Polyester Cover

but talking with the rigger he said the reason we getting the chaff is the halyard builds up twist over a period and no matter how carefully you put the sail up, the 2 parts will rub. he suggested to put a swivel (wichard part 2465) at the masthead deadend which we have done.

shall be interested to see results over time

cheers,

Also, 12mm is really very thick for a Dynema halyard. What size boat is this? Guessing it's reasonably sizeable given a 50m main halyard.

Unless he already has the same as you and I. Our 2:1 main halyard is about 45 metres. Load wise, you’d certainly think 10mm would be enough. Maybe spend* the ‘saving’ on a grade up in material.

Unfortunately I have discovered that the cover has worn on my Liros Dyneema Plus main halyard. Just 4 years use (10k miles) but the outer has parted.
This means replacing nearly 50m of otherwise good rope. 12mm so not cheap. (Anybody want a couple of c.20m sections of used 12mm Dynamic Plus?)

The rigger is checking for any sharp edges, but seemed to be from around where the stopper is on when fully hoisted - in spite of moving the wear point and end for ending twice.

Two questions
(a) Any longer lasting alternative to Liros Dynamic Plus (dyneema core is essential for our boat and this application) - though this Liros has generally been excellent in every other role on board (sheets and other halyards) ?
(b) Any other suggestions beyond Jimmy Green Marine (who are generally great) to source from ?

Thanks

You only need a cover on it where it runs through clutches and is put on a winch. Just strip it off and carry on, would be my recommendation. It will work better without the cover.

I have 12 years and at least 50,000 miles on mine and they're fine. I was careful to eliminate all chafe points at the time I put them on, with the mast down.

Another question -- have you checked WHY it wore so quickly? Are you using it with mast truck sheaves made for wire halyards? Is there a bur on them, or somewhere else? They should last much longer than that.

One issue you may have is that Dynamic Plus is a cruising dyneema with a quite thin core which fits loosely in the jacket. I would always recommend racing dyneema for halyards (and for everything else, actually).

12m performance cruiser, with with a generous fully battened main. 12mm Liros Dynamic Plus was the factory fit ropes when got the boat.

I'm going to agree with Flaming here. That seems like a bad choice. If you don't elect to just strip the cover and carry on, I would go with 10mm RACING dyneema. I have 12mm dyneema halyards on a 54' boat.

I did this with a dyneema spin halyard (new Marlow racing !) that inexplicably developed a damaged section to the cover when moving inside the mast. It has never repeated it and I am at a loss as to what caused it. Never mind.

That is truly beautiful! :love: Laborious, but worth it!! Thanks for posting that.

If the OP is otherwise happy with the halyard, and for some reason wants to keep the cover on it, that would be the way to go.

I wonder if the Technora extra cover someone mentioned can be done that way. Would be great to have that grippy stuff where the halyards run through clutches.
