new rigging

[Jack B]

hi,
i am currently rerigging my boat and need to buy a reel (100m) of 3 strand 8mm, 3 strand because I want to easily splice it. i wan to use it as haliyards ect and i wondering what material is best to use marlow, polyester? I want to get it for a good price but i don't want to get some poor grade stuff.
thanks jack

If you are determined to use three strand, then I suggest you go for pre-stretched polyester - you don't want much stretch on halyards. if you google pre-stretched polyester, you should be able to find a good price. Normally I'd recommend Barry Edwards who trades on e-bay as Boatropes but I don't know if he stocks that type of rope.

No need to splice if you use Braid on Braid. It can be spliced, but it is just as easy and secure to use a halyard knot as recommended by Selden - instructions on their website. Just used it on my topping lift, kicking strap and both main and genoa halyards.

dyneema spling is relatively easy (the man on English Braids at SIBS said so ! ?

Halyards

The OP seems characteristic of individual sailors who delight in being different. However cleverness does not mean being different, lots of people have gone before. Hence 3 strand rope is seldom used on yachts. Despite it being splicable. Indeed it is now only found on anchor rode.
Halyards need to be stretch resistant. I have used spectra at 6mm on my 21fter for jib halyard and found that stretches annoyingly. 8mm is better. However rope on wire is still the best.
In reality a dyneema or spectra halyard is barely adequate to my mind and don't skimp on size.
A halyard can be knotted onto the sail. Indeed this is better as it allows you to vary the length of halyard from mast head pulley so vary the wear point each time you tie on a sail. A bowline is fine. There is loads of strength in the spectra it is stretch that is the problem.
I grant if you have sail hoisted for days on end stretch is not so much of a problem but it is in my kind of sailing. Short races with perhaps 3 jib hoist and drop over 2 hrs. (3 spin runs)
Personal point here much excitement as racing season opens this Sunday.
Rethink the halyard thing good luck olewill

I agree with the stretch issue. I have three-strand topping lifts, because the different texture makes them easy to distinguish from halyards and reef pendants. They have a lot of "bounce" in them, which is not a problem for this application but not what I would want in a halyard.

Find a good Youtube video and splicing braid is not that hard.

If you find spectra or dyneema too stretchy try Vectran, which has about 25% the stretch and nearly the same breaking load.

Mind you I find that after it's been used, spectra stretches very little - but then my main halyard (the only one then goes up and down) is 12mm, down to 9.5 dia when loaded and measured just in front of the cleat.

Agree, not much 3 strand rigging on boats now for a reason.

The newer dyneema sk75 is actually stronger and less stretch than steel wire rope of same dia. Film stunt riggers use it or similar mostly now. But eye wateringly expensive Amsteel blue winch wire from ebay might be a poss for halyards, but still not cheap.

Then make shackles from the offcuts

Surely if the chap wants to keep costs down on what sounds like a 20ft triple keel cruiser then prestretched polyester is perfectly adequate, indeed sensible. Dyneema?, Vectran?; total overkill on a boat like this. Thousands of boats had and still have running rigging made in three strand.
Give the guy a break...

This is for a Pedro/Seahawk 17 ?

If so I agree with the above. Its not a hot racing machine. Stick with pre-stretched polyester ( even just ordinary polyester!) Forget all the expensive high-tech stuff.

I would also keep it down to 6mm rather than 8mm. Saves money, will fit the cleats and sheaves on the boat/mast more easily and is more than strong enough for a boat that size.
The only thing you need larger than 6mm is the sheets for ease of handling. 10mm will be just the ticket there.

You sure you need as much as 100m all the same size?
