Dymeena to sort my Genoa furling line problem?

[sailorman]

Thanks Guys. I will pay more attention to the tension when unfurling as a first step and consider de-coring braid on braid as second step. ....So just the outer braid will have the required strength then?

wadda ya think. its std OEM with Harken

But very stretchy - my Rotofurl E with the 150% genoa was impossible to bring in unless head-to-wind.

I effected a vast improvement by putting the 8:1 Enkes winch, off the reefing pad on the mast, onto the cockpit combing, mainly to use as a jobbing winch - but on occasions I've resorted to an 8" handle.
It's worked a treat for 18 years and the self-tailing Antal, that replaced it, actually brings in the last two leach-lines and gets the luff down on the fully battened main.

OP, what size is your furling line? I recall that it was quite thick. That could be part of the problem.

On my new (to me) Hunter Horizon 26, I found that the roller furling was stiff some times but OK at others. This seems to be driven by the amount of backstay tension that is applied at the time; too much tension on and it becomes stiff.

I haven’t completely got to the bottom of this yet, but I think that it is to do with the wheel-type halyard diverter that is fitted at the top of the foil, which comes into contact with the mast as more backstay tension is applied.
As I say, this is a work in progress for me, but it might be worth the OP checking.

Backstay tension = high loads on the furler bearings

I used to have a lot of problems with my furling line somehow jumping off the drum and creating the most awful jams. Even if I was handing the furling line just a single slack revolution would usually be enough to cause a problem. Drove us nuts... However, I added a short strop to the block that feeds the drum and the whole issue disappeared So, before you start replacing the line with Dyneema, I'd definitely check the drum feed.

The next issue is sticky bearings (I suspect that the bearings are totally shot) but that's this winter's project ...

It is 7/8mm. It was reasonable to handle but the drum was pretty full when the sail was out. On reflection I do believe that I, for one, have been negligent about tension when letting the genny out. I willgive another try but keep the ideas re de-coring some of the line in case there are still problems.

A problem with almost all furling systems is that tension is applied to the bearings asymmetrically because the halyard has to be located off centre (because the stay takes the centre position). One half of the bearing race pinches the balls (ahem) whilst the other loosens them as you apply tension, leading to resistance to turning.
