While not vital i always put a few turns of a strong whipping twine around the tack of the main and around the foil. One final trick is to put one or two cable-ties on the loop at the tack of the main to stop the loop dropping off the hook if you relax the halyard tension excessively. As Zanshin suggested, one turn of the outhaul around the halyard winch should be enough tension while furling. It is of course essential to keep a little tension on the outhaul when you are furling to make sure you get a tight furl. Step 3 seems to be the magic since it gives a more horizontal pull on the clew when unfurling. 1&2 reduce the pressure of the rolled sail against the slot at a point which is about halfway up the mast.
2) do not over-tension the halyard 3) move the stopper on the boom back to at least the halfway point along the boom. Approximately half of the chord of the mast should be enough. If you get any jamming of the sail in the slot when unfurling there are three things you can do to reduce this possibility 1) not too much mast bend. This needs to be done BEFORE you furl since otherwise if you relax the tension when fully furled it will only release tension near the head instead of all the way down the luff. You do not want the luff of the main to get stretched permanently so it is good practice to release the halyard a little to relax the tension if you are not going to use it for a while. The latter being particularly critical since it is on a top-down furler. I do the same thing and mark my genoa and gennaker halyards. Once the correct tension is found i mark the halyard with a coloured pen at the Spinlock so if someone releases it by mistake you immediately know what position you need to re-tension it. If you tension too much you will then get vertical folds parallel to the mast and near to the luff. You need to tension just enough to get rid of these. Gerald, I think the previous replies have probably covered yr question but if the halyard is too slack you will get horizontal folds in the sail. I do however sometimes furl the main while running - or on a beam reach with boom extended out on the lee side. There is a good amount of rake in the mast head - vessel is balanced perfect with less than three degrees of weather helm at most.Īs Zanshin pointed out we always hold slight tension (slip thru hand type) when furling the main and vis-versa when hauling out.
I tensioned the halyard a bit more to try and “fix” this but it seems to have made furling the main just slightly more difficult.

I’m concerned because I can’t get the luff completely free of wrinkles maybe one forth down towards the foot. It always seems to me that it goes a little slack over time. I also find it is a good idea on our rig to tighten up on the furling line just prior to unfurling. Zanshin is spot on about boom angle when unfurling and keeping a level of tension on the outhaul when furling to keep the sail smooth as it enter the mast. Twice I have had the clutch released in error with the sail furled and it took some time to get it out of the mast to reset the tension. If the sail furls and unfurls easily, following the other rules of in-mast management, then lock it off on the clutch and make sure that no one messes with it. I would suggest you think of it as you would when hauling up a normal sail, Just enough to get rid of any vertical or horizontal creases - but no more. Too much tension on the halyard will make life difficult just as too little will cause creasing and problems also.
You are asking about the 'Halyard' tension controlling the luff of the sail not the tension on the out-haul and furling lines? I read your post a little differently to Zanshin. Somewhere on this forum is a very long but informative thread about all aspects of in-mast furling.
