New Genoa Halyard.

[doug748]

Perhaps Dyneema or something similar in low stretch. I need about 25m of 12 or 14mm stuff.

Can anyone recommend the cheapest source or alternatives. Thanks.

Setup an ebay search. Stuff comes up in those lengths.

14mm diam is very thick. What size of sail do you have? My 35 M of 8mm dynema from Lyros has a swl of 4.5 tonnes which will lift my boat. It has a very tight outer cover rather than the soft one that many cruising dynemas have. Hence I had to change the clutch jaws. I bought it just before covid for £220 just before the chandlery closed. The laminate sail is 27 M2.

I originally made the mistake of getting a halyard a size too big & it really caused problems when trying to drop the mainsail SH. Because it is now free running I do not have any issue hoisting with the 8mm line on my old hands & I normally wear some fingerless gloves anyway. The advantages on the drop far outweigh any issues on the hoist.

I have since bought 30 M of 14mm dynema for laying moorings ( no outer cover) from Wetworks at Burnham on Crouch. They specialise in internet sales, but a phone call to Dave the owner often gets a couple of coppers knocked off as well.
They have a small chandlery there & I normally go in & do a deal with him direct. Saves postage as well. No good to the OP in the SW, but OK for anyone near Burnham.So worth a mention.

If you are going for dyneema, 10mm is a good compromise between strength and line handling requirements. We use 10mm on our 17.8m mast for the main halyard. It is over specified for your loads I suspect but any smaller is hard on the hands.

Yes, I see a couple of offers that may do the job. Thanks. The boat is 32 ft masthead sloop. Not sure of the existing but it is much fatter than necessary.

I may go for that, there is a 12mm alternative as well. May go to the boat and take off the existing to make up my mind...

I think you will find that 10 mm is more than adequate. When I was destructively testing Dyneema soft shackles the break load of 6 mm line was higher than the 10 mm stainless steel shackles tested earlier. It is incredible stuff.

If it is a genoa halyard & you leave it up on a furler most of the time, then there is not an issue with the hands. You will only be adjusting the tension on the winch as you sail. That would be the same regardless of diameter. If you do multiple sail changes during a race that is something different.

Not cheap, but this Liros Dynamic Plus is good stuff - and certainly don’t need anything bigger than 10mm Liros 10mm Dynamic Plus Dyneema - Sheets, Halyards, Control Lines

If a pure cruiser, probably don’t even need the dyneema core on a genoa halyard for a 32 footer.

Great, that is worth knowing, I have been looking at some of his offers. I only have to figure out if I can get away with 25 metres now.

Thanks everyone.

We use Marlow basic 12mm polyester line on the genoa and jib halyards. Little point on dyneema for this application in my experience if not racing. We use 10mm marlow racing dyneema on the main and mizzen halyards. Far more benefit here in my experience ?

Five years ago i changed both genoa and mainsail halyard with 10mm deneema from SVB (Gleistein xp) on my 32ft

When I changed the original Doyle mainsail supplied with my boat as standard to a better quality one I had to change the halyard. This was because I could see the creases coming & going in the sail as the braid on braid halyard was stretching so much. The original sail was poor quality & was also very elastic so it was not obvious.
The point of this, is that if at any time you improve the quality of sail, you will need a decent halyard with limited stretch.
With all due respect to Geem's comment #11 above I think it has nothing to do with racing. It has to do with proper sail set. Many people do not worry too much about the quality & set of sails because they are "cruising". To me the art of sailing includes setting the sails properly & getting the best use from them & the rig.
But to each his own & others have different priorities . That is understandable. Just not how I sail.

I was specific about the genoa halyard on a smallish pure cruiser. Your comment refers to your mainsail.
Like geem, I believe the mainsail is a different proposition and does merit the dyneema core in its halyard. (In fact we have dyneema core in all running rigging, but a bigger and faster boat)

As you probably know I do a fair amount of sailing miles. Always very keen to get the best of of my boat. Mainsail tension can be improved dramatically by a dyneema halyard but in my experience genoa/jib tension is far less variable. I could pretty well tension my genoa and not need to adjust that tension with a polyester halyard for the whole trip. It may need tweeking if the the wind goes from light to strong or vice versa. With the same polyester halyard on the main it would never be at the correct tension. I used to have a dyneema halyard on the genoa but put the polyester one back on and now use that dyneema halyard for the spinnaker.

I sail a 10.10 metre boat (33 feet in old money). Changed all my running rigging to 10mm, I can't think of any good reason to go to the expense of dyneema it is not as it is lifting a heavy load and others have said it slips in winches.

As you are in the SW, Rope Locker in Dawlish might be worth a visit.

Just for Clive (Coopec) rigging his new boat. This guy will make Dyneema to your spec at very good price. He is in Bibra Lake.
