Re: Low friction rings for single-line reefing

Have single line on first two reefs and double on third. Built boat and main to accommodate. Have blocks sewn into sail. Using dyneema/spectra lines. Deck set ups have minimal angles for bends and good blocks. Jeff is right you need to do everything possible to decrease friction. But with Dutchman I can hoist,reef and strike myself without leaving the cockpit. Unlike in boom I can go to a reach or stay on a beat trim the jib ease the main sheet reef and resume course without need to wake anyone. On single line reefs can shape a bit with halyard tension and not pulling reef way tight. More so then I would get from in boom. Have power on all winches but grind the last few inches when worrying about over tensioning.
Spaghetti is longer but less lines. Dump under hard dodger so non issue. Everything runs through clutches so winches left free. ( usually leave main sheet on winch with clutch open).
Don't like in boom.if you lose halyard whole sail pores on deck and would be uncontrollable for me.
Don't like in mast.have had jams and too much excitement.
So far single on first two and double on third has been just fine.

Re: Low friction rings for single-line reefing

Here's a simple solution for less friction in reef cringles, both single line and double line systems: Goļot roller reefing insert cringles http://www.goiot.com/pdf/p48a.pdf

Re: Low friction rings for single-line reefing

This is a very interesting discussion, as I installed a two line-per-reef system last year.

The tack lines go up to a Gargauer block attached to the tack, then back down and back to the cockpit. This gives a 2:1 purchase at the tack. This works great with very little friction.

The clew lines just go through the clew eye, and there is more friction than I'd like. I tried a block there, but you could no longer pull the clew down far enough. A block with its associated piece of line attaching it to the clew, was too long overall.

I wonder if these low friction eyes would work instead?

Edit : just saw the Gioits, very cool

Re: Low friction rings for single-line reefing

RichH, do you have experience with the Goiot roller cringles? I have seen adds for them over the years and have been intrigued but would like to get a testimonial before I pull the trigger. I have been pretty happy with the single line reefing set up on my 34. My biggest point of friction has been the (reefing) tack cringles. (Not so much a problem on the clew reefing cringles). I have tried the micro block and ring thing but the block has a nasty habit of flipping over and twisting the reefing line resulting in a heck of a lot more friction. The Goiot cringle, if it works, would be a perfect solution to my friction problem.

Re: Low friction rings for single-line reefing

My main has single line reefing with special blocks that get sewn right to the sail. Low fiction and works great.

Re: Low friction rings for single-line reefing

It seems, at least on my setup, that to get the mainsail fairly flat requires the ability to pull the clew right down to the boom. So only a block fixed right to the sail would work.

Re: Low friction rings for single-line reefing

MarkSF: You can make the dogbone quite short and achieve that with an Antal low friction ring. I'm using a longer soft shackle for my dogbone because that gives me the ability to also hook the stainless side onto the reefing hook.

The typical way to do these dogbones is with a piece of sewn webbing. Look at a high quality sail and you'll probably see them on there.

Re: Low friction rings for single-line reefing

Yes the tack has a webbing dogbone, with rings on each end. I simply attached the block to the ring. The length of the webbing is not an issue at the tack.

But at the clew it would be - I really need to get the clew right down to the boom.

My clew line go through the eye like this, don't think that using low friction rings would help much here.
