Jammed Furler

Hi all. This hasn't happenned to me (yet) but I was just wondering, always wanting to have a contingency plan: If you have your genoa furled 30% or so in high winds and the furler jams so that you can neither furl nor unfurl, what do you do?

No Hijackers Here

I don't consider talking about the details of your's, mine, or anyone else's halyard and furling systems 'off topic' in a 'Jammed Furler' thread. If you don't know exactly how and why your system works then the idea is to learn about it - Before it Hits the Fan :eek:

But halyard wire wrap is one of the common causes of a jammed furler...:confused:
I'm not quite sure if this was a timing issue or who or which post this refers to. If it is 'wire' in particular my answer is - get rid of it - as it serves no purpose that the current breed of low stretch lines can't do better. Again I'm not saying to do it as I did without changing the sheaves but between Meat Hooks and Kinking... just make it go away...... ;)

I've got more time - actually had to do some office work . . . some clients need to get their priorities straight. ;)

I looked closer at some masthead photos I had taken and now have a clear understanding of what went wrong. Thanks guys for the help - still learning after all these years.

Fortunately, the SS U-shaped halyard fairleads are not riveted to the mast. Those beefy roundhead screws seem easy enough to remove. However, with a second look, there is a U-shackle with a clevis pin connected to the snap shackle, which can be unscrewed, allowing the wire end to slip through the fairlead without unscrewing.





Also see two signal lines already strung through the fairleads. Will they interfere with the wires? Looks like I'm going aloft in a couple weeks, after launching.

Amen to that Stan... definitely like the new Spectra-based lines for halyards... stronger than wire, lighter than rope, with about the same stretch as an all wire halyard.

TB- Have fun... hope it is a windless day when you go up...

Giu-

Spectra, dyneema...basically six of one, half-dozen of the other... very similar in characteristics... both are forms of ultra-high-molecular-weight polyethylene... and it does stretch, about 1-1.5% depending on what rope it is, and the construction method.

Yes Sir! It is done! The sheaves seem happy too. Hope Giu is right about Dyneema.
Off course I am...I have all my ropes in Dyneema...its light and strong...just remember if you can, have the 2 diameter system, where all the light thin rope goes up the mast, all hand contact rope with thicher section.

Even my back stay is 100% dyneema...all of it..

Everything that goes up is lower diameter dyneema, including all 6 halyards.



The back stay also, from mast top to inverted V and inside stern purchases (2 of them).



Then once it goes to your hand, it goes to a larger diameter, but still dyneema.





I like it a lot...

So far I only have a couple of Dyneema/Spectra lines on board, one is spliced onto a much thicker line for handling. I have to learn how to do that splicing trick. Being a poor cruiser, I worry about UV weakening the lines, so the first two are a bit of an experiment, but I'm not going back to wire. I have a colleague in the club who has his entire rigging in fibre.

Yes..the UV may be a problem...but not that serious..I believe you're in Europe, right?? I am in the hottest/sunniest country in Europe and years go by before I need to replace them..you're OK..Besides, I only replace the outside lines..all the inside mast are normally ok

Hey don't knock Brussels just because its afflicted by Eurospeak! We have beer, chips, moules and chocolates (just to mention life's essentials) and I bet you can't name twelve famous Belgiums (That's a standard Trival Pursuit question).:D:D:D Actually its not hot enough to smell bad and it rains so often a lot gets washed away too.
Yes my boat is overwintering in the Port of Brussels (there, you didn't know we had one). See www.bryc.be for the marina.

Then there's the story of the Kiwi bird. At the first sign if trouble, the Kiwi bird starts flying around in circles. Faster and faster, tighter and tighter. Eventually he flies so fast and tight that he just flies right up his own butt until he disappears!

You could be like the Kiwi bird and let go the sheets and just sail around in circles until the sail rolls itself up or you might try letting go the sheets and taking them to the foredeck and wrapping it up manually. It may not look too pretty but it'll get the sail out of harm's way so you get into safe shelter where you can work on the problem.
