{Stus-List} Furling Trouble - Peter to the Rescue!

Other halyards can cause a problem at the top of the mast, especially if the
luff on the furling sail is close to max length. Seems most sail makers
believe in getting every inch they can in the luff of the sail, even in
furling sails and sometimes full hoist can result in a binding situation.
Were your headsails made specifically to fit with your furling gear and rig?

The sail maker who built my 130, specifically for my boat and furling
system, even after he measured everything with a tape, made the luff too
long and it initially bound up in the spin halyard.  After that I asked him
to cut it back by about a foot and he did it no charge.

A restrainer may help but I believe if you have trouble with the sail
binding on halyards at the top of the mast now that you won't have enough
room to install a restrainer and still get full hoist on the sail.  You may
need to shorten the luff, either at the tack or the head to effectively use
a restrainer.

I think Steve's problems are solved but I have had furling problems on and
off on Tangerine for the last 4 years - some sails furl easier than others
and last year I thought I had the problem solved but this year back to
square one.  

I have to use to much force to furl the sail.  I took the genoa down and
first time ever the halyard is frayed.  Not happy with that!

I think the other halyards are interfering and so I will try and take them
out of the way and make sure everything is clear at the masthead and will
invest in a restrainer for next year.  
Will also check tension on backstay but I don't use a lot of tension and
maybe that is part of the problem.

Congratulations on the fix--at least it didn't involve any boat bucks!

One suggestion--to maintain as much of the end plate effect on the foot of
your furling sail as possible, 

try using the pennant at the head of the sail. This won't change the halyard
length and if the pennant is wire, 

the sail will probably furl just as easily since a wire pennant can't really
'wrap'.

This keeps the foot of the sail close to the deck, trying to trap as much
wind as it can, with the tack

off the deck by only the length of the furling drum from the deck, instead
of the additional distance

caused by the length of the pennant. 

My sail maker claims the loss at the top of the sail, because it is not as
high, is more than made up by the gain 

at the foot.

I finally got back to the boat today and was checking to see if I did any

damage to the swivel and/or drum bearings.

There does not seem to be a problem, they turn smoothly, but under some load

might be a different story.

I hoisted the head sail and tried to furl it, ok until half way then the

halyard started catching again.

Peter Deppisch came by and noticed 3 things. He agreed the swivel was too

far from the halyard sheave, hence allowing the halyard to wrap. He also

noticed a small (8") pendant at the tack which I was not using. His theory

was that the previous owner used the pendant to get the swivel up closer to

the sheave as John suggests below. He also noticed the halyard shackle was

big and bulky, probably adding to the tendency of the halyard to get caught

and start to twist. Fortunately I have a spare jib halyard which has a much

smaller shackle (probably the one which was intended for the furler all

along ;-) ).

Well the fix was simple. Use the pendant at the tack, switch to the other

halyard and presto - furling and unfurling without any grief! John, I

checked for a kink and did not see anything, but perhaps I was just

'willing' the kink away. Will look again.

Thanks to Peter for his excellent help today, but I will not close this case

until I can furl and unfurl the sail in some good wind.

We have the older Harken unit.  Have found that backstay tension has a

significant impact on the ease of operating the roller furler.  Need to

slack off before operating especially if it is blowing as the sail puts a

lot of tension of the unit.  Have also installed a wire pennant from the top

of the sail to the bottom of the swivel so the swage fitting for the halyard

shackle is right at the sheave.  This keeps the upper furler swivel very

close to the sheave so halyard wrap is not possible.  We keep unused

halyards clear by keeping them tensioned and tied off to the side to the

outer shroud.

Can you get the sail down to inspect the swivel and halyard itself??  Is the

halyard wrapped on the head stay? - if so will probably have a kink in it.

While we are on the subject, when our foil rotates, it seems like it is

resting metal on metal inside the drum causing a scraping sound and

friction.  Any comments?

Hi, I am new to furling systems (mine is Harken Unit 1.5, newer, about 6

years old) so I hope I haven't screwed something up.

Was out yesterday in 22 to 28 knots, under #3 and full main, had to put in a

reef after a while since we were getting overpowered.

Fair bit of tension on the backstay to reduce weather helm.

When we came in we furled the headsail, but due to gusty wind it was a

'lumpy' furl.

At the slip I went to unfurl and re-furl to straighten the sail and it would

not unfurl.

Hard to tell 45 feet up there what was going on but fairly apparent a spare

halliard was fouled and twisted in the furling system.

I managed to free the halliard but the sail still would not unfurl.

Once I realized I still had the backstay tensioned, I let that off and the

sail unfurled.

(I don't think the backstay tension was excessive - it's a Navtec hydraulic,

and the pressure gauge was only up to the first mark on the dial.)

OK now the real problem starts: now the sail will not re-furl.

Obviously I have to get up there and see what's going on but curious about

similar experiences of the group.

My dock neighbour had similar problem and devised a way to keep the

halliards away from the swivel.

That's all good but right now I'm worried about whether the swivel is

damaged in some way.

Thanks,

Steve Hood
