Jib halyard too tight

I was out on an Aloa 34 yesterday with a new boat owner teaching him how to sail.
I let him do the for-deck work to get used to it.

I asked him to release the topping lift after the main was raised and he released the jib halyard instead.

After both sails were flying well I went up to tighten the jib halyard as I didn't think it was a good idea to leave it loose.

At the end of the day we tried to roll up the furling jib and the pennant was wrapping. He has a storm jib hanked on and it has a long pennant about 3 feet on top as the storm jib is pretty small about 110.

I let out a couple inches on the jib halyard and the sail was able to furl fine.

So my question is, is this normal, does excess tension make the roller furling top roller seize or does this mean the top bearing needs to be serviced?

The lesson from the Icarus story is not about human failing.
It is a lesson about the limitations of wax as an adhesive.
If you have an engineering problem solve it.

Re: Jib halyard too tight

Indeed a general question. No info on age (furling), how tight etc. On a 34 ft you probably had the assistance of a winch. Could be tight then, but then you are experienced.
This leads to the conclusion that it wouldn't hurt to have a look on the bearings.

Re: Jib halyard too tight

Drop the sail check it at deck level. Use his pennat to load it up against halyard tension. Might just need a clean and lube. Or could be old and junk but clean and lube will help if its not total junk.

Re: Jib halyard too tight

I know on my last boat (Jeanneau 43DS) if the main halyard was too tight the in mast furling system would not work as advertised. I wouldn't be surprised at all if tension would prevent the jib furler from working based on my experiance.

Re: Jib halyard too tight

Common problem. Even after I replaced the bearings (smooth as silk now) I still leave the halyard just tensioned. Often the furler instruction tell you to release the tension prior to furling... which for most cruisers means we shouldn't have tensioned it in the first place. Others simply warn that excess halyard tension can cause trouble.

I would hope sail makers would endeavor to design furling jibs for cruisers so that little halyard tension is needed.

BTW- it's "foredeck", not for-deck. As in fore and aft.

Re: Jib halyard too tight

I have always understood (perhaps erroneously) that furler bearings are made of material that requires no lubrication and in fact that lubrication will cause dirt/debris to stick to the bearings and seriously accelerate wear.

I know that because of this understanding, I have never lubed furler bearings and I can't recall having them stick - maybe I'm just lucky.

But I would check before lubing.

I also don't think that excessive luff tension helps - the forestay should maintain the sail shape and the halyard should be just tight enough to remove any wrinkles in the luff. At least that's how I sail my boat.

Some are stainless and can benefit from cleaning and lube, some are Torlon (plastic) or equivalent high strength material and should only be flushed. The Torlon bearings only last so long until UV and salt abrasion wear them down, they break, and things get bad fast. Stainless balls can corrode and require lube. The lower ones generally fail first.

Re: Jib halyard too tight

From Harken manual
Halyard Tension
The jib halyard should be firm, but not too tight.
Tip: The luff foil system supports sail along its length so halyard tension is used only to shape sails, not to support them. Use enough halyard tension to remove some wrinkles along luff of sail. Do not tension halyard enough to cause vertical wrinkles in luff of sail. Tension to adjust position of draft in sail to suit sailing conditions. Halyard should be firm but not tight. If in doubt, release halyard tension. To protect sail, ease halyard when boat is not in use.

Furlex furlers come with a tube of special grease to use on both upper & lower units.
Not all furlers are grease-less.
