Looking for some input -
We have a Sirius 21 with a jib furler. The furler has recently started to twist when winding it up and now snags (can not complete wind). We have lowered the mast and moved the jib hayard placing (down 2") to avoid it binding with the furler, but no luck. Does anyone have any ideas? Does forestay and/or back-stay tension influence furler performance?

Thanks for any help -

The furler is a Plastimo (France) 406. Forestay appears fine, however may be a little slack....

Is the foil twisting? Is the foil a single unit or multiple sections?
Wish I could see it operate...

Yes the foil does twist. I might take a video. Will take a day or so. Do you think forestay or backstay tightness can influence this?

Stay tension --both too tight and too loose -- definitely has an impact on furling. You may also want to verify that the swivel at the jib head rotates easily.

If it's causing the foil sections to separate, maybe.

Look all the way up the luff and try to decipher what exactly isn't working or what is happening. Sometimes the halyard wraps around the forestay extrusion because the angle of the halyard isn't acute enough to prevent this. It is simply called "halyard wrap" and a halyard restrainer attached to the mast, to give the halyard the proper feed to the upper swivel is all it takes to fix. But, you have to identify the issue first.

Hello Sirius Pete,

We had a similar twist problem on the old, but new to us furler on our recently restored and launched 1972 CD Typhoon. At first look I believed (as mentioned in Barnacle Bill's post) that the angle of the restrainer was too shallow. We brought down the jib and examined the top part of the furler. It was a bit squeeky and grindy when we turned it by hand. While doing that maneuver we noticed the word "grease" at a small indent between the turning parts. By golly! A squirt of Lithium grease at that indent and at the one at the turning drum near the deck and all is well. I know that goes against the conventional wisdom of only rinsing with water, but that is what was stamped on the parts and it worked. Fortunately, I did not need to go to Greece to get a repair!

I've had the same problem (I think), and it turned out to be the swivel at the jib head.. it was not swiveling properly. Cleaning and grease did the trick.

Group,

First, my apology for my delay!

So, I used the ideas for lubing the swivel (dry lubricant) and saw immediate improvement. Another issue we found was the jib we were using did not go to the top of the mast, which through the distance between the head of the jib and the mast-head, created the halyard wrapped as mentioned by BB. We have since made halyard extensions, which we are hoping to try this weekend.

Thanks everyone for your help! Enjoy your summer on the water!
