Re: Stus-List Roller Furling Line

[Rjcasciato via CnC-List]

Edd..

My simple thinking is that you have to roll up at least the length of the
foot of the 150.  So why not measure the sail and then mark the line and
wind that much onto the drum.  When you put the sail back on, puling on the
line should wind it up correctly

 

I probably would add a foot or two just in case

Listers,

 

My roller furling line got ultra-tangled in the drum and I ended up having
to drop the headsail and cut it all out. 

 

I bought some new line and am going to install tomorrow, weather permitting.


 

So here's the question. How many feet of line should I have wrapped around
the drum before putting the sail back on? 

 

I'm running with a 135% headsail, but want to have enough on there to
accommodate a 150, if I ever make a change. 

 

All the best,

 

Edd

Re: Stus-List Roller Furling Line

[Josh Muckley via CnC-List]

Mine is nearly a 1:1 ratio and I usually keep a minimum of 3 or 4 wraps on
the drum (~2ft).  Then the add the length of the distance from the drum to
the desired termination (~35ft).  Then add the length of the foot.  A 150%
will be about 24 ft.  So 65ft should be sufficient.  Remember that you have
to have enough space on the drum for all your line.  Too large of a
diameter rope and too many wraps are going to jam up in the drum.

There is a good amount of consideration given to line stretch when talking
about halyards.  I had never considered it with my furling line until the
other day when I was sailing furled in heavy air.  The furling line would
stretch and during every gust the furler would unroll about a half turn.
As the gust passed the drum would roll it back up.  This was obviously
negatively impacting the headsail trim.  I will definitely be moving to a
low stretch alternative.

Re: Stus-List Roller Furling Line

[Dennis C. via CnC-List]

Make sure the line leads out of the drum 90 degrees to the forestay. If yours 
doesn't move the first block up or down until it does. 

Second, it's a lot easier to wrap the sheets around the furled sail to get the 
correct number of wraps. 

Buy extra line.

Josh,

Fntastic! Thanks. I bought 80-feet of line and will wrap 27-28 feet or so 
around the drum. That should do it. 

You da man.

Re: Stus-List Roller Furling Line

[Edward Levert via CnC-List]

If able, measure the old line you cut off to get a rough idea of how much
line to buy. Total up the pieces. Then raise the sail with no new line
around the drum. Roll up the sail by hand again with no line attached to
the drum. Now attach the new line to the drum with the sail fully furled.
Add 2 rolls by hand. Now unfurl the sail as usual and this will wind the
new line on the drum. Cut the tail if necessary to the desired length.

Re: Stus-List Roller Furling Line

[Indigo via CnC-List]

Those 2 rolls by hand will be on the "wrong" way as the only way to get them on 
the drum is to rotate the sail and furler.  I think the better way to get the 
extra rolls on the drum would be to wait to attach the line to the drum until 
the sail has been over furled by hand several times. I am thinking 10 times 
plus ( probably have to take off the sheets) - then attach the furling line. 
Remember that when furling the sail in windy conditions your sail is going to 
be much more tightly wound round the headstay and thus require many more turns 
of the drum to get it fully furled.  Remember that you will usually be furling 
with the sail under a little bit (or sometimes with a lot) of load and the 
furling line will be more tightly wrapped round the drum allowing for a larger 
number of turns before getting "jammed". 

Btw I suspect that your problem in the first instance was caused by letting the 
jib unfurl without having any tension on the furling line.  Happened to me once 
- had to spend a good hour on the bow while it was bouncing up and down in big 
waves / big wind at the entrance to Narraganset Bay.  I now insist on keeping a 
little tension on the furling line as it runs when the sail unfurls.

Re: Stus-List Roller Furling Line

[Josh Muckley via CnC-List]

Why not wind up as much line as is needed on the drum first?  4 or 5 or 10
wraps or whatever, plus the foot length (24').  Now raise the sail.  When
you pull the furling line it will roll up the sail.  Just like normal.
Seems easier than trying to control a sail while manually rolling it
without any other control.  Yes you do have to pay attention to the
direction of the spool.  Yes you may have to add or take off wraps which is
relatively easy to do by re-wrapping or unwrapping the jib sheets not the
sail.

Re: Stus-List Roller Furling Line

[Indigo via CnC-List]

I may be totally wrong, but I don't think there is a direct correlation between 
the length of the foot and length of furling line. The marker the diameter of 
the drum, the longer the circumference and thus the longer the line required 
for one rotation - but the circumference of a roll of sail will be potentially 
very different.

Re: Stus-List Roller Furling Line

[Josh Muckley via CnC-List]

Jonathan,

You are correct there isn't a direct correlation between furling line
length and foot length.  As I previously stated mine happens to be roughly
1:1 averaged over the entire furl.  I am simply visually approximating the
diameter of a full drum compared to a full sail roll.  You're right the
circumference of the roll during the first few wraps is much smaller than
when the entire sail is rolled up.  Yet the diameter of the drum stays
nearly the same.  I'll have to measure the actual length of line needed to
furl next time I think about it.  It will be interesting to see exactly
what the ratio is.

Re: Stus-List Roller Furling Line

[ALAN BERGEN via CnC-List]

I do it the way Josh recommends.  I also put the maximum amount of line on
the drum.  It's easier to furl when the drum is full (the line is coming
off a larger diameter full drum) than when it's less than full.  Also, keep
some tension on the furling  line when letting out the jib, also
recommended by someone.

Re: Stus-List Roller Furling Line

[Marek Dziedzic via CnC-List]

If you want to be really picky, there is a direct correlation. Not necessarily 
1:1, but it is obviously, there.

 

I went with a standard double braid, but we have much less choice locally. A 
lower stretch line would be probably better, but I never noticed the stretching 
that someone mentioned a few messages before. This may depend also on the size 
of the boat and the size of the genoa - mine are only 27’ and 135%.

 

With this kind of line I bought double the length of the boat plus some safety 
margin. I think I bought 70’, but at $0.5/ft. the extra 10 ft. did not matter. 
That $5 was a good insurance and what I cut off the end will be used, for sure, 
somewhere else.

Once you get the length figured out, get rid of the core for that portion that 
will be on the drum.  The cover can handle the load and it lies nice and flat

Re: Stus-List Roller Furling Line

[Daniel Sheer via CnC-List]

Just replaced the furler line on Pegathy. 145% Genoa on an LF38 80' of 3/8 
double braid. Works well, 10' tail when unfurled, figure 8 to hold the line on 
the drum. A bit more than a half foot of stretch under load when reefed, I 
figure. That's less than a half turn of the drum. I figure that if it's blowin' 
that hard, the boats close to hull speed, and I ain't gonna worry about it.

Wind conditions while rolling up seems to have an effect on how tightly 
the sail wraps, and how much cord gets used.

Re: Stus-List Roller Furling Line

[Chuck Gilchrest via CnC-List]

Measure the diameter of the drum full of line with the sail out all the way. 
Divide by 2 and multiply by pi (3.1415). That will give you the "circumference" 
or length of rope for one wrap around the drum.  Yes it will change as the rope 
unwinds from the drum but for the sake of argument, let's use the max 
circumference as a constant.  Measure the distance from the drum to the furling 
line cleat, taking into account any guide blocks or rollers that the rope needs 
to pass through.
Now furl the jib taking care to count the number of turns on the furler from 
fully deployed to fully furled.

So the length calculation will be:
Circumference of rope on drum times the number of furler turns plus distance of 
drum to cleat plus 7-10' or so extra rope to allow line to be handled in 
different spots of the cockpit.

Depending on conditions such as wind and jib sheet tension while furling, my 
jib can be furled either really tight or rather loose and sloppy. Tight almost 
always requires extra turns on the furler.

Re: Stus-List Roller Furling Line

[Joel Aronson via CnC-List]

Chuck,

Why not measure from the mid-point of the drum's circumference?

Be sure you have enough line to wrap it around a winch and tail it.

Re: Stus-List Roller Furling Line

[Chuck Gilchrest via CnC-List]

Joel,

You could use the mid point as an average, but I also leave 3 or 4 wraps of 
rope around the drum when the jib is fully furled just to have a margin of 
error when the jib is furled too tight or too loose…

And like Fred said, you could also use a calculus to determine the exact length 
you needed.   Or measure the line that came off the drum to begin with…

As was previously mentioned, some folks will remove the core of the rope that 
sits on the drum to avoid extra bulk.  My only concern with that approach is 
when someone uses a winch to furl their jib.  Removing the core from a double 
braid rope will reduce tensile strength by nearly 75%.  I’m more inclined to 
use a single braided rope such as NER Regatta Braid, Novabraid Sprint, or 
Samson Control DPX which will flatten out when spooled on a drum, but will 
retain 100% of tensile strength.

I may be totally wrong, but I don't think there is a direct correlation between 
the length of the foot and length of furling line. The marker the diameter of 
the drum, the longer the circumference and thus the longer the line required 
for one rotation - but the circumference of a roll of sail will be potentially

Re: Stus-List Roller Furling Line

[Richard N. Bush via CnC-List]

 I had not heard of it either, but the furling line for my boat had the core 
removed for the part of the line which was wrapped around the drum...which is 
most of the line...it took a bit getting used to the feel of it, but it works, 
(which is the most important part)!

I'm really low tech - hoist the sail at the dock, connect the furling line
.. roll the sail up by hand (by manually rotating the drum) .. go a few
extra turns - to someone else's point, undoing jib sheets later is easy if
need be.

You guys are overthinking it :)

If the question is "how much line will I need" then I guess you could do
some math - or just measure the old line.

Re: Stus-List Roller Furling Line

Not stupid when you size the line accordingly.  What is stupid is getting a 
line wrap when trying to furl/unfurl because the line will not lay right on the 
spool with all that bulk .

10,000+ ocean miles has proven its efficacy.

I am with Steve on that. You can over think it, if you want to. But if you buy 
about 2x the boat length you should be fine. At the price you pay for a line of 
this diameter you can add extra 10 ft. for good  measure.
Of course involving calculus is so much more fun.

Joel,

You could use the mid point as an average, but I also leave 3 or 4 wraps of 
rope around the drum when the jib is fully furled just to have a margin of 
error when the jib is furled too tight or too loose…

And like Fred said, you could also use a calculus to determine the exact length 
you needed.   Or measure the line that came off the drum to begin with…

As was previously mentioned, some folks will remove the core of the rope that 
sits on the drum to avoid extra bulk.  My only concern with that approach is 
when someone uses a winch to furl their jib.  Removing the core from a double 
braid rope will reduce tensile strength by nearly 75%.  I’m more inclined to 
use a single braided rope such as NER Regatta Braid, Novabraid Sprint, or 
Samson Control DPX which will flatten out when spooled on a drum, but will 
retain 100% of tensile strength.

Chuck,



Why not measure from the mid-point of the drum's circumference?



Be sure you have enough line to wrap it around a winch and tail it.

Divide by 2 and multiply by pi (3.1415). That will give you the "circumference" 
or length of rope for one wrap around the drum.  Yes it will change as the rope 
unwinds from the drum but for the sake of argument, let's use the max 
circumference as a constant.  Measure the distance from the drum to the furling 
line cleat, taking into account any guide blocks or rollers that the rope needs 
to pass through.

Now furl the jib taking care to count the number of turns on the furler from 
fully deployed to fully furled.



So the length calculation will be:

Circumference of rope on drum times the number of furler turns plus distance of 
drum to cleat plus 7-10' or so extra rope to allow line to be handled in 
different spots of the cockpit.



Depending on conditions such as wind and jib sheet tension while furling, my 
jib can be furled either really tight or rather loose and sloppy. Tight almost 
always requires extra turns on the furler.

I may be totally wrong, but I don't think there is a direct correlation between 
the length of the foot and length of furling line. The marker the diameter of 
the drum, the longer the circumference and thus the longer the line required 
for one rotation - but the circumference of a roll of sail will be potentially 
very different.

[Robert Boyer via CnC-List]

Removing the core on the begiining of the wrap on the drum allows the line to 
lay more evening and reduces the line build up.  You can maintain the core in 
the portion of the line that is handled.  I've been dong this for many years.

Re: Stus-List Roller Furling Line

[Marek Dziedzic via CnC-List]

in heavy wind conditions I need extra two wraps of the furling line around the 
drum to furl the sail completely.

Wind conditions while rolling up seems to have an effect on how tightly the 
sail wraps, and how much cord gets used.
