Furler problem after standing rigging replacement

Just had standing rigging replaced. Kept the furler. Rotostay 2 and foil, getting on now without doubt. Came to re rig the genoa tonight and on rotating the furler, either direction, resistance is felt once each rotation. Gradually increases then lets go with a mild bang and rattle. Sounds like it's somewhere up the foil. Wondering if something inside the foil is snagging the forestay wire, not good. Any thoughts or experience of this please before I call the riggers back? Thanks.
 
Just a thought -when the halyard was re rigged did they remember to put it through the diverter, if you have one. Halyard wrap?
 
Is the turnbuckle catching inside the bottom of drum ? Did they replace like for like in terms of fittings ?

I doubt its halyard wrap as that usually causes the whole to stop turning ... needing to be turned back again ... I assume all was working fine before - so no need for modifications ?

Your description is typical 'snagging' inside the drum / furler extrusion ...

I'm surprised the rigger didn't check furler rotation on completion of the job ... I would be inclined to call them back .... you paid money .. you want it to work.
 
Sounds as if you need to get the rigger back to check it out, especially if it never gave trouble before. Good luck.

Turnbuckle okay. No modifications just replace wire. I suspect snagging in the foil and the noise at least sounds as though it's up the foil somewhere. Have emailed riggers and will be ringing them soonest.

This always makes me smile .... I know some rec'd reducing tension on halyard - but I know on all the boats I've had and sailed - reducing tension on halyard can lead to halyard wrap .... so care needs to be ...

I am glad it makes you smile, but is most certainly a feature of my roller furling, and I have never, ever had halyard wrap.

Anyway, good to rule it out by OP.

It comes from over tensioned halyard .. where it can cause the furler extrusion to 'curve' slightly and then drum or extrusion has friction on the stay ... the inner plastic extrusion can be damaged as well ...

Its easy to find the happy medium and it would only be those who like to play with luff tension that would need to touch the halyard ..

No doubt you will disagree ... buts that's life !!

Glad you now agree with my post 3.

The installation manual for my roller furling suggests in the trouble shooting that stay tension could be a reason for lumpy furling, though yours sounds rather excessive for this.

I don't know how yours is designed, but last time I had a new forestay, the new top swage no longer fits into the top of the foil, even though the wire sizes were the same. Perhaps your swage is also a bit bigger, and the foil just about fits over it, but with too much friction when put together. Is the top of the foil a smooth circle or is there a join that can catch? The squared off nature of the swage perhaps is giving the lumpy nature.

Is it possible that the foil set too high?

Please let us know what the riggers find.

Mmmm interesting thoughts about the top swage and top of the foil.
The foil appears okay viewed from the deck even with binos. Can't see inside it of course.
I'll certainly update once the riggers have looked.
 
"Pye End" .... "Glad you now agree with my post 3."

Actually you assume more than I intended .. my explanation of over-tensioned halyard is exactly what it meant ... over-tensioned. It means that a blanket statement as you and some others have said on other threads about releasing tension is incorrect.
Tension reduction is only needed when halyard has been over-tensioned in the pursuit of extra luff tension.

Second that OP has not even hoisted his genny yet !! So how would halyard tension be an issue ?

Just over a week ago I tightened the genoa a bit to improve sail shape for some hours of up wind work. Didn't grind really hard, enough to improve the shape in the fresh breeze. Came to wind it all in at the end of the passage and it didn't want to furl. Remembering the extra cm or 2 or luff tension, I eased it back again, just a tad, and it furled away as normal. This wasn't the first time, but was the first time this year. Now it could have been resistant for one of the reasons you give, but I suspect that it is because of worn bearing in the top swivel, idk, but what I do know is that a bit of extra tension made it very hard and lumpy to furl. My system is no spring chicken, and I am sure you will also have read the OP comment about the one in question, so may well have worn parts. I hope this fuller account will explain my comment made in post 3, and why I am sticking to it as a potential reason for a hard to furl sail.

My post was post 3. OP gave that information out in post 5. Acknowledged by me post 14.
 
Many moons ago, I changed my forestay, dismantled the original ans slid off the foil sections (6 I think)...big mistake not marking them.
Reassembled all and seemed to have the problem that the op is describing.
I dismantled all again and laid it all out on the ground to find that the foil sections were slightly distorted if not Reassembled as original, well with 6?sections and reverse ending it took about an hour to get the combination looking presentable, so I re rigged it all and all was tickety boo..
