I've been searching about the issue, but didn't find anything related.
My problem is with rolling furling just unwinding a bit of sail and gets stuck. Helped by hand but it twisted a bit and didn't go. Think problem could be at top, so I will appreciate some guidance, as where to start looking or trying.

thanks in advance.

If you look at the top swivel, can you see the halyard wrapping around the forestay? If that's all looking OK (i.e. not wrapping), then you could have an over-wrap on the furling line inside the drum itself. You may need to manually unwind the furling line and re-do it.

What Paul said.....

I assume you have a problem with the genoa. I posted a thread this week dealing with my mainsail doing the same. That thread is at

http://www.sailnet.com/forums/gear-maintenance/160793-mast-furling-issue-new-post.html.The suggested solutions do not really address a similar issue with a headsail, but it may give you some inspiration.

My solution was reducing tension of the halyard, This may apply to your issue as well.

Good luck

Yeah is is most likely halyard wrap. I assume you have already made sure any spare halyards you might have aren't interfering. You can also try changing the halyard tension to see if it releases.too tight with bad bearings might bind, and too loose will be more prone to the halyard wrapping. If necessary un wrap the sail and drop it down so you can inspect the swivel. Make sure it turns smoothly even with load on it.

This is a common issue and there have been a lot of discussions about it in previous threads. The "halyard wrap" problem occurs when the top portion of your halyard, from top roller to the top halyard block, wraps tight around the stay, stopping the roller from turning. It's often caused by too little halyard angle from the top sail roller up to where the halyard exits the top block so that the halyard can wrap around. When tensioned, the halyard needs to actually be pulled back at an angle to the foil a bit so it can't wrap around when the foil rotates. This can be a difficult thing to picture in words but is likely what's happening. The furling manufacturers have installation diagrams which specify the optimum distances and angles for the top set-up which might clarify the idea. The distance and angle from top roller to block is the key.

Here you go for a discussion of 'halyard wrap' and what to do about it:

Think have a couple of issues as you all suggested. Halyard is tangled with auxiliary halyard. But weather has been nasty and is difficult to work with 40knt wind and the vessel jumping like a bull. Thanks to you all. Will post later how story end if the boats stands the beating.

 

[donjuanluis]

I took a zoomed picture that may illustrate the situation...

 

[Aquarian]

Might be a long shot, but have you checked your forestry/ back stay tension. I once fought a furler for months before it occurred to me (thanks to advice from a sailnet member) to tighten my back stay. My boat was rigged with an adjustable backstay. Increasing the tension straightened the furler and solved my jammed fuller issues both for furling and unfurling.

 

[RichH]

Halyrad wrap.
From your pic, It may be that the splice in the terminal end of the halyard is too thick and too long and the splice cant enter into the throat of the masthead sheave. If the halyard was fully tensioned, it wouldnt be 'sticking out' like this and the connection of the halyard would be 'behind' the top swivel and between the swivel and the mast.

If you have any 'pendent' between the tack of the sail and the bottom drum of the furler, remove it or resize it. Otherwise, that halyard is not all the way 'up', the halyard between the mast head sheave and top swivel and the stiff halyard splice is fouling the top swivel. I offer betting odds that there may be a smaller diameter high tech line with small length splice in your near term future. The only near term cheap solution would be to cut the splice off and learn to tie a 'halyard hitch' and then seize it well.

BTW once you apply a halyard hitch to a halyard you can NEVER safely go up the mast on that halyard !!!

 

[smurphny]

I think Rich has it. That halyard looks very thick (probably double braid), jamming in the sheave before pulling the sail all the way up. The distance between the head of the sail and the sheave looks very close which would normally be a plus except for the thickness. If there is a pendant on the tack, maybe shortening it a bit, 2-4" would work. I would try that or a knot before springing for a new halyard.

Aquarian's comment is also true. If there is a lot of sag in the forestay, it makes it harder to rotate the furler because you are trying to rotate an arc instead of a nearly straight line.

 

[THEFRENCHA]

Had same problem and being lazy found an easy fix
Attached spinnaker halyard on top shrivel
Prevents from turning /keeps it aligned
Bottom part turns and roll the genoa

Works fine since ....at least 2 years!

 

[travlin-easy]

I had the same problem, and in my case as well, the top swivel was binding. It was a lousy furling system, and I replaced it with an Alado roller furling system and never had a problem since. The Alado is rated very high by Practical Sailor Magazine and it is among the least expensive systems.

Good Luck,

Gary

 

[donjuanluis]

I had solved the issue. What I did was to lose halyard, and start playing with the furling, rolling, unrolling, until the end of the halyard came aligned with the stay, then put some tension, not much, but enough to keep it in that position. So we are sailing again with full genoa. Thanks to sailnet and all you people.
Regards.

I am having an issue but it is with a hanked on mariner furler, seems stuck at the top as if the upper swivel is frozen.

I'm not sure what you mean by a hanked on furler...never seen such a creature!

If you think it is a swivel problem your best bet is to untie your sheets and manually unwrap the sail then drop it to the deck and check the swivel. Make sure you test the swivel under load. It may spin free when it is loose, but jam under load.

I did drop the sail and the stay was still torquing at the top.

Yeah I hadn't seen anything like it before, check it out....google "mariner roller furler" and there will be a link to a pdf that is the brochure. (Sail net won't let me post a link to another website :/)

So the upper swivel part on the diagram is what was frozen, however an update....we have been getting showers here in southern California and this morning I went to turn the drum and went fine as if the moisture loosened it. Not sure what it means for the long run though.

Thanks!

What you have is the same as the new structural wire furlers used on many very large racing yachts. forestay turns with the drum. Facnor is one of the manufactures of the new furlers which are use on many of the large racing trimarans. the new systems use a zipper luff or soft hanks. the swivel is part of the forestay so it does require a good look often because a failure could result in rig failure. the draw back is that you need to remove the forestay to service the upper swivel.

Thanks for the reply! I'm scratching my head now because after our recent rainy wx it is now spinning freely (perhaps it was crusted over?). Makes me wonder if I ought have it inspected anyhow....
