Roller Furling Halyard Wrap

Yesterday while sailing when I went to deploy my genoa it only came out part way. Each time I would re-furl it the amount of sail that would come out grew smaller. I discovered that when deploying the halyard would wrap around because the upper part of the furler which is supposed to stay still was turning. I had to wait until I was at anchor, then unfurl it by hand. Lower the sail so I could re-wrap the furling halyard. Raise the sail and furl it.

Today we unfurled and furled the genoa a number of times under load and unloaded and it worked fine every time.

I have no idea what I did to cause he problem in the first place nor what I did to fix it. Has anyone had a similar experience and any idea what caused the problem or how to avoid it in the future.

Thanks

Re: Roller Furling Halyard Wrap

Did you check halyard tension before you lowered it?

That is probably the culprit. Halyard stretch over time, something might have slipped or been inadvertently loosened.

Re: Roller Furling Halyard Wrap

If the swivel is stopping more than a foot or so away from the mast halyard sheave (eg if your jib is not a full hoist luff dimension) then this can be an ongoing problem.

There are a couple of easy solutions.. add a pennant to your sail to get the swivel to the top of the foil, or install a halyard restrainer. It will not allow your tensioned halyard to parallel the foil for any distance.. that's what allows the halyard to wrap.

Re: Roller Furling Halyard Wrap

I did not check the halyard tension but I'm pretty sure it was pretty sure it was taught. I did try winching the halyard up but still got halyard wrap.

Re: Roller Furling Halyard Wrap

The top swivel is some distance from the top of the foil and I may have to use the sheave solution. I was hoping to avoid that but if it has to be done; it has to be done. It seems odd to me that it has only happened once and didn't happen again. The sail wrapping didn't look right either yesterday when it happened. It occurred to me that somehow the sail was preventing the top swivel from swivelling. I don't know how that is possible because the top of the sail is attached to the bottom of the lower portion of the swivelling mechanism, the part that is supposed to wrap.

If, say, your swivel ends up 3 feet from the top of the foil, if you add a 3 foot pennant (just a line extender - it could be wire or a piece of Dyneema or equivalent) to the sail that will move the swivel up high enough that halyard wrap will be much less likely. You can add the pennant to the head, or the tack, depending on whether you want the increased visiblity with the sail up higher off the deck (pennant on tack) or just want to get the swivel up (pennant on head).

You do need an accurate measurement of the 'distance'.. difficult to judge aloft.. if the pennant's too long you won't be able to get proper halyard tension.

For guaranteed elimination a halyard restrainer is best. BTW it needn't be a sheave, there are padeye style fittings that work fine. It does involve a trip aloft to install.

Re: Roller Furling Halyard Wrap

It could also be that the bearings are failing in the top swivel. If the ball bearings are synthetic, they can develop flat spots or even break which could cause it to intermittently jam.

Re: Roller Furling Halyard Wrap

A pennant won't always work. The masthead on my Pearson puts the halyard parallel to the forestay no matter how high up the foresail goes. A halyard restrainer that changes the approach angle is the only solution. You might have the same problem, what kind of boat do you have?

My Pearson has an Isomat NG37 mast. It was used on many boats, listed here:

Re: Roller Furling Halyard Wrap

The top swivel is not working properly, some grease can solve it.
Another possible problem is the angle of halyard with the stay. It should be more than 8 degrees. You may need to install a block on the mast.

Re: Roller Furling Halyard Wrap

Hey,

What model furler it is? Furlex models recommend a Halyard restrainer, which can wear out and require replacement.
