Need help, rolling furling get stuck after unwinding 5 feet of sail

I've been searching about the issue, but didn't find anything related.
My problem is with rolling furling just unwinding a bit of sail and gets stuck. Helped by hand but it twisted a bit and didn't go. Think problem could be at top, so I will appreciate some guidance, as where to start looking or trying.

thanks in advance.

Re: Need help, rolling furling get stuck after unwinding 5 feet of sail

If you look at the top swivel, can you see the halyard wrapping around the forestay? If that's all looking OK (i.e. not wrapping), then you could have an over-wrap on the furling line inside the drum itself. You may need to manually unwind the furling line and re-do it.

Re: Need help, rolling furling get stuck after unwinding 5 feet of sail

I assume you have a problem with the genoa. I posted a thread this week dealing with my mainsail doing the same. That thread is at

https://www.sailnet.com/forums/gear-m...-post.html.The suggested solutions do not really address a similar issue with a headsail, but it may give you some inspiration.

My solution was reducing tension of the halyard, This may apply to your issue as well.

Good luck

Yeah is is most likely halyard wrap. I assume you have already made sure any spare halyards you might have aren't interfering. You can also try changing the halyard tension to see if it releases.too tight with bad bearings might bind, and too loose will be more prone to the halyard wrapping. If necessary un wrap the sail and drop it down so you can inspect the swivel. Make sure it turns smoothly even with load on it.

Re: Need help, rolling furling get stuck after unwinding 5 feet of sail

This is a common issue and there have been a lot of discussions about it in previous threads. The "halyard wrap" problem occurs when the top portion of your halyard, from top roller to the top halyard block, wraps tight around the stay, stopping the roller from turning. It's often caused by too little halyard angle from the top sail roller up to where the halyard exits the top block so that the halyard can wrap around. When tensioned, the halyard needs to actually be pulled back at an angle to the foil a bit so it can't wrap around when the foil rotates. This can be a difficult thing to picture in words but is likely what's happening. The furling manufacturers have installation diagrams which specify the optimum distances and angles for the top set-up which might clarify the idea. The distance and angle from top roller to block is the key.

Here you go for a discussion of 'halyard wrap' and what to do about it:

Think have a couple of issues as you all suggested. Halyard is tangled with auxiliary halyard. But weather has been nasty and is difficult to work with 40knt wind and the vessel jumping like a bull. Thanks to you all. Will post later how story end if the boats stands the beating.

Re: Need help, rolling furling get stuck after unwinding 5 feet of sail

Might be a long shot, but have you checked your forestry/ back stay tension. I once fought a furler for months before it occurred to me (thanks to advice from a sailnet member) to tighten my back stay. My boat was rigged with an adjustable backstay. Increasing the tension straightened the furler and solved my jammed fuller issues both for furling and unfurling.
