Rope Treatments on J/111 Standing Rigging

Cordage is available from riggers, stores and online, but what sets CYR’s rigging apart is the special treatments.  Quality materials are only part of the story, and we can improve performance and longevity with a few special touches.  Here is what we like for the J/111

Custom covers have moved from the GP boats into club race boats.  For the part of the line that gets handled, we have great options to improve performance. Fibers like Technora, Cordura and Vectran can be blended with standard polyester to improve grip on winches and clutches, as well as improving abrasion resistance.  They can be left natural (tan in the case of Technora and Vectran) or dyed black. I like tan for halyards since the lighter color takes marks better, and black for sheets.

This picture best illustrates what we can add to halyards to make them hold in the clutches better.  A good blended cover (here it’s Technora, Polyester  and Cordura) increases grip and reistance, but key is the size increase. A stiff core added to the inside of the existing ropes core makes the line larger-in this case right up the max size for the clutch cams-as well as stiffer.  The stiffness is actually more important than the size increase, as the line doesn’t flatten under load.  I have very good data on what the proper bulks and stiffness’ are for all the clutches used on race boats.

On the other end of the line,  chafe protection is another place we can upgrade a halyard.  Here is a Dyneema chafe tip on top of New England HSR core.  This saves the halyard tips from chafe and failure. A good way to determine if this will be beneficial is to look at the old halyards.  On the J/111 we’ve noticed that the jib and spin halyards show lots of wear on the stock Crystalyne halyards.  The jib halyard seems to get some forestay/foil chafe, and the spin halyards seem to get articulation chafe.

For the mainsheet gross tune, I really like a short tapered area for where the line runs when the fine tune is trimmed.  In addition to having a good clean block (the broken double in this picture was replaced with a Harken 57mm fiddle with a nice round forged shackle) the taper is extra low friction to make trimming and easing the fine tune mainsheet even easier.  The line is Alpha Ropes SSC which I think is a wonderful mainsheet as it’s light, taperable and has incredible handling due to it’s knobby cover and blend of Dyneema, Cordura and poly in the cover. Great line and I recommend it over much more expensive braids. 

For spinnaker sheets on assymetric spin boats, and jib sheets with inhaulers,  a tough cover is a must.  Here is a 9mm spin sheet with a blended Technora/Polyester cover.  The Technora is a very tough fiber that grips winches well. Depending on your winches we can also use fiber blends like Vectran, PBO and Dyneema, but the Technora/Polyester blend is going to great for most applications.

Stretch Test!

On my “Good Ideas To Do At Some Point In The Future Maybe When Things Quiet Down” (GITDASPITFMWTQ) list there has been an item that’s been hovering near the top of the list (above “Right grate American novel” but below “Close the door you’re letting all the heat out” ) has been a bench test to see how the different materials, treatments and brands of rope we use here at CYR perform in one of the most important metrics we have: stretch.

As cordage evolves, it almost always trends in 2 positive directions: lower stretch and higher strength.  In the last couple years strength has become less relevant as the finished size of the rope becomes the limiting factor.  If we really wanted to, we could have 4mm cores on 35′ racing boats and not be worried about it blowing up.  Stretch has become more important. If you look at the “flavors” that Dyneema generations come in,  the most recent iterations have become more and more stretch focused.

Dyneema SK60 (most similar to Spectra 750) was strong and light, but stretched, crept and wasn’t significantly stronger than the aramid fibers it was compared to. SK75  (Spectra 1000) was lower creep and much stronger. SK78 was lower creep, but not stronger (this is now the “standard” Dyneema from most marques). SK90 was stronger but no better on creep than 75, so has been supplanted by SK99 (better in creep and stronger).  DM20 is… weird and I’ve never used it.

In the past year,  I’ve made halyards with each of the ropes shown below.  All of these are 3/16 or 5mm so comparable in size and would yield a ~5/16″ halyard.  From the top:

MARLOW SK78 MAX The MAX line of Marlows Dyneema cores is their version of heat setting.

Defining characteristics: It’s black!  The black comes off on your hands. Second stiffest rope in test.  Looks cool. The braid angle is exactly average in this sample set.

Sizing:  The 5mm core measured 4.4mm after being loaded.  Round? Not really,  unloaded it measures 5.3 one way and 3.69mm the other

Dumb observation:  If this were a car, it would be an Audi A3.


Defining characteristics: Silver. Not as stiff as HSR or Max, but stiffer than STS78.  Longest braid angle.  Smells nice.

Sizing:  The 5mm measures 4.6mm loaded. Round? Meh.  It measures 4.73mm one way and 4.2 the other.

Dumb observation: If this were a football player, it would be Odell Beckham Jr.  Never heard of XTM either, but it’s good.


Defining Characteristics It’s white (comes in 7 colors too) it’s floppy compared to the Vectran and the Heat Sets. Very shallow braid angle. Gets super stiff once loaded.

Sizing 4.9mm under load Round? Round!

Dumb Oberservation While typing this up, I dropped all the samples on the floor. I could tell the STS78 just by feel. I bet if I were to total up all the STS78 (aka STS75 aka Endura 12) I’ve spliced, it could go to Belmont harbor from the shop and back.  Lets put that on the GITDASPITFMWTQ list!


Defining characteristics Gold! Much more abrasive than any of the Dyneemas.

Sizing 4.2 under load. Round? NO.  2.9mm one way, 4.6 the other.

Dumb Observation I totally forgot I had any Vectran in stock.  It’s gone from about 40% of my high tech cordage to exactly .8% ( I have sold one Vectran rope all year) If this were a car it would be a Pontiac, because in a few years people will be all “Pon-Tee-Yak? What’s that?”


Defining Characteristics It’s stiff! Really stiff. When you put a cover on it properly the crew all hates you for the first race because it only gets stiffer when covered.

Sizing: 5.1mm under load Round WOAH, they make round rope! 5.2mm one way, 5.3 the other. About as round as it gets.

Dumb Observation If this were a car it would be a WRX.  Not exactly pretty, some people don’t like how they feel but does everything really well. And I sometimes cover it with orange cover, and WRX’s are often covered in tacky aftermarket gear as well.


So how did they do?  Well, nothing broke and no one got hurt, which is good.  Before I share any results though, lets talk methodology.  Before we talk methodology, lets make a bunch of disclaimers for how rudimentary my testing methods are. Before we do that,  have you listened to Astronautalis? He’s great, and I think it’s a damn shame that the yanswer to the previous question is always “who?”

METHODOLOGY I spliced all the samples into 10′ lengths. Then loaded everything to 1000lbs with a dwell of 30 seconds.  The samples were length checked, and respliced to 10′.  Why respliced?  The construction stretch on new rope is huge.  Even heat set ropes lose some of their “set” when coiled and handled.  Splicing takes up a long length of rope, but then releases some of that once it’s under tension. Everything was loaded again and checked again.

To test stretch,  I loaded all the samples to 200lbs, did the CYR Load Distribution Procedure (hit rope with mallet, kick hydraulic cylinder) then then loaded everything to 100lbs.  A clamp was made off at the dogbone holding one end of the sample. Then the tension was added slowly until 1000lbs was reached and stable. The distance between the clamp and dogbone was then measured using a digital mic. The samples were then tested in reverse order after being left flat on the bench to minimize bending the rope.  After that test, all the samples were taken to 2000lbs with a dwell of 1 minute, then retensioned to 1000lbs.

ROPE Stretch @1000lb Stretch @ 1000lb 2 Stretch @ 1000lb after 2000lb load
Yale Vectrus 55.25 31.37 26.99
Marlow MAX SK78 21.64 19.52 11.64
Alpha Ropes D Core XTM 78 24.32 17.53 9.78
New England STS78 29.9 22.93 14.33
New England HSR 20.35 14.42 8.84

There is lots of interesting information here.  All the ropes developed less stretch after being loaded, with the benefits increasing with the amount of load applied.  This fits with what conventional but often ignored wisdom, as most riggers recommend preloading your halyards before use.  For mains I like to load the main halyard around the boom at the mainsheet strop, then tension the mainsheet as hard as possible. For genoas, jibs and code sails I use the tack fitting, tension with a winch, then “banjo” the halyard from the foredeck by pulling aft on the line.  For spinnakers I go get coffee and think about the weather.

The vectran stretched more, significantly more, than all the flavors of Dyneema.  This is not a surprise, but keep in mind that Vectran should in theory have less creep than Dyneema SK75 and below over time, although SK78 and Vectran are supposed to be comparable.  I will be modeling this, but since creep takes a long time to develop, I’ll be loaded the samples over a weekend and checking on Mondays.

The non heat set STS78 showed the next most stretch, but comes with a caveat.  When setting the lengths to 10′ on the samples, I took nearly 100mm  of initial set out of the STS78, whereas every other sample was more like 5-60mm after the splices were set.  This means that if using regular Dyneema for length critical applications like strops or pennants, it needs to be set under tension. For best results I usually exceed the working load by 3x and have had good results with regular Dyneema after that.

The Heat Set Dyneemas all performed very well.  The Alpha XTM stretch a lot initially but settled down after hitting our target load, and did particularly well after getting tensioned to 2x the test load. The Marlow MAX started better than the XTM but was overtaken after it was tensioned to 2000lbs.  If you’ve got lots of experience with rope, this is very intuitive after handling the lines; the XTM starts out being much less stiff so it stands to reason that it would stretch more initially. The XTM braid angle however, is much more parallel to the rope, so once all the stretch is removed, it makes sense that it would show less load stretch.

The New England HSR did the best, especially once tensioned.  This again fits with the “feel” one gets from the rope, as the HSR is the stiffest running rope I have ever used.

This was a fun test and will be updated as the creep results come in.  The good news is that all the Dyneema lines performed really well compared to the state-of-the-art-circa-2005 Vectran.  If we accept these numbers, and assume a boat like a T10 has these ropes on the main halyard.  The T10 sailors, being good preppers and not tired from the party, preload their halyards before sailing.  It’s windy out, but the ropes only stretch: Vectrus 130mm,  MAX78 56mm, XTM78 47mm, STS78 69mm, and HSR 42mm.

As always, let me know if you have any rigging related bits for the GITDASPITFMWTQ list.


The overnight time on the bench has been surprisingly tied up, first with a steering cable and now with loops over the weekend, so I’ve decided to do some shorter term testing.  Figuring that on a bad day, a windward leg of a race takes 30 minutes,  I let each sample dwell on the bench for 45 minutes at 1000lbs after a 1500lb set.  As it turns out, not much at all happens in 45 minutes.

Yale Vectrus 0 978
Marlow MAX SK78 0 982
Alpha Ropes D Core XTM 78 0 982
New England STS78 0 980
New England HSR 0 986

The ropes didn’t move. Even a little. Testing was done with a metal square clamped to the bench even with the dogbone, and after the first sample I kind of knew the score, and that this  test wouldn’t be very exciting.  The most interesting thing is that the load numbers at 45minutes were down off of 1000lbs, but I’m willing to chalk this up to the bench itself, as there is always some movement and it’s not particularly exact as a dedicated testing rig would be.  An interesting proof to this is that once the ropes were taken to 1500lbs, and then tension released to below 1000, then brought back up to 1000lbs, the numbers actually went UP before they went down.  Could be the load cell itself, the loops, the winch, the tensioning rope (1/2″ vectran)

Here are some videos of the best and worst stretch from the test.  This was done after the actual testing, so the clamp zero is a bit off, and the camera isn’t in line, but even so you can see the huge difference in stretch

With no change in dimension and negligible change in load, it seems like creep in the context of something like a windward/leeward race is not a significant factor. My understanding on creep is that it takes a combination of load/time and temperature to occur, and that it happens on the order of days and not minutes or hours. If I ever end up going upwind with the same tension on a halyard for days, please send help, as not only MIGHT creep be a factor but that sounds like an absolutely boring race and I don’t want to do it.

The interesting observation from the setup for this test was how much all the ropes initially moved when being spliced and set to 10′ lengths. So, for kicks,  I also took a 6′ piece of STS78 and did the same test. This piece of rope only had a quick 1500 set, then was taken to 1000lbs.  This one did grow, by about 28mm, and dropped tension to 658lbs.  This fits my own experience in that prestretching any halyard on the bench makes it perform better once on the bench.  Heat Set Dyneemas only really needs the ends stretched after splicing, and Vectran doesn’t seem to either (Dr. Bam Miller of Oyster Bay Boat shop thinks this is due to the higher coefficient of friction with vectran, but he’s not a real doctor and I don’t think Bam is even his real name.) Regular Dyneema does grow by quite a lot,  the splices set as well as the rope itself elongating with load. The good news is that this settles down with a decent prestretch or lots of use.

My news for customers is this:  get a Dyneema halyard. If you want more performance get a Heat Set Dyneema halyard.  If you really want to come in and talk about creep for a boat that does buoy racing, please excuse me while I bang my head on the test bench.

Creep Update 1 HSR heat set Dyneema

The HSR sample was left on the bench at 1000lbs from Friday afternoon through Monday morning,  the length was unchanged and the load was at 960lbs.  Over 60hrs with no dimension change is pretty good!  Assuming you were on a J105, and this was your main halyard, and the ENTIRE Mac race was upwind on the same tack in the same amount of breeze, you still don’t have to worry about creep in a halyard.  So far this testing just reinforces my recommendation for heat set Dyneema halyards, aft standing rigging and critical control lines.

Creep Update 2 STS78 Dyneema

On Monday I loaded the STS78 sample to 1000lbs and planned to leave it there through Wednesday. As it turned out,  it was left until this morning, so about 60 hours just like the HSR.  In theory, this would be the most creep prone sample.  Heat setting as a process removes the constructional stretch, but in theory also reduces creep since it accelerates it during production and aligns both the fibers and the molecuslar structure of the rope.  Regular Dyneema should show considerably more constructional stretch, as well as more dynamic strech and definitely more creep.  The constructional stretch on this sample should have been mitigated by all the cycling (multiple times to 1000, 1500lbs, once to 2000lbs) but I was still expecting to see some creep as compared to the Heat Set.

Instead,  the sample is exactly where it was left on Monday, showing no dimension change.  We’re at about 16% of break load.  Although normal working loads for racing/cruising running rigging are about 20%, I feel that 1000lbs in this case is pretty indicative of a typical max-normal halyard load on a boat that would use 5mm Dyneema core.


Over the weekend (OH THE BEARS…) I decided to continue the creep testing by going with a higher-than-recommended working load on the STS78 sample.  So far, the loads  tested for creep have been loads you would likely see on the water with a 5mm piece of rope. No creep has been observed in any of the Dyneema lines, even in STS78 which is non heat set Dyneema and should in theory show creep.  The fact that this piece has been prestretched by being cycled to 1000 (many times with long dwell), 1500 and 2000lbs has made stretch pretty minimal, but I was a bit surprised we couldn’t generate any creep (OR ANY PASS RUSH, BEARS).

To try and generate creep, I loaded the line to 40% of the breaking load (2440lbs). This is well above any SWL for running rigging, and would not likely be encountered on the water. After round 55 hrs the rope had elongated by just under 1mm (UNLIKE THE BEARS SECONDARY WHICH ELONGATED ENOUGH FOR 48 POINTS).

This is still really good!  There was no prestretch beyond getting the rope to tension, so you’re likely seeing construction stretch as much as anything.  Getting <1mm over 3048mm at this % of break load is incredible. You could debate whether we’re seeing construction stretch (probably) or creep (unlikely) but it’s nice to have this data (AND THE INEVITABLE TOP FIVE DRAFT PICK IN 2016).

If you’re curious about the angry parentheses…. 

Rope Tails for Clutches

Many control lines and sheets on race boats get led through clutches and other passages daily before racing. Jokes aside, pushing rope is never easy, so people have come up with lots of tricks for this like tape to keep the rope straight, messenger lines, cable ties and lots of other tricks.

These big boat sheets go through clutches and blocks every day they’re used, so a more elegant solution was needed. A piece of Nylon stitched into the tail of the rope makes a stiff but small section of rope that should run through any clutch.

Here’s an exciting video of rope!

Lifeline Lashings

T10 Backstay Update

The Tartan Ten is a staple of life at CYR. At this moment I have a T10 boom on the bench, and another strapped to the ceiling; there are 2 T10 backstays in boxes on my desk, a forestay just came off the swager, and there are 2 boxes of halyards and sheets on their way out the door UPS. T10s are the alpha and the omega around here! For every cool big boat project, there’s a dozen T10 bits, so I take them pretty seriously even when their owners come in looking for innovative blender solutions, or a shade of rope that matches their favorite beer can (both true)

Anyway, one of the specialty T10 products has been the fiber backstay. Proud to say that if you see a fiber backstay on a Ten it’s probably one of ours. One of the original pre-2010 backstays came in from the cold the other day, so I took the chance to see how it’s held up. This has 5 seasons of use including regattas, beercans and distance races. Pull test results will post shortly, but for now lets look at the condition.

The top eye is covered in chafe sleeve to keep it safe near the masthead crane. You can see this thimble is too large, as the eye has been crushed a bit by the top of the masthead crane. We started using smaller thimbles or no thimbles after 2011. The loads on this are light enough that a smaller thimble won’t distort under load, and even the pin alone would offer plenty of bend radius.

Here you can see what 5 seasons of the backstay flicker ring have done to the chafe sleeve on the backstay: not a lot This is a 3/16″ stock stainless ring, and it hasn’t made a dent in the backstay itself.

Here you can see where the top batten hits the backstay. The very first time we tried Dynex Dux as a backstay, the T10 top batten was fuzzing up the backstay on the first sail, so the chafe sleeve was added. The chafe sleeve is quite slick and tough, and the tight weave and stretching during splicing make it snag free. Very pleased to see how fresh this looks entering year 6.

We’ll break this soon and see how much of the rated 5T strength is left.

We broke this recently, and saw how much of the rated 5T strength was left…

The backstay broke at 5,640lbs, or approximately 53% of original rated strength after 5 years of normal/heavy use.  What’s funny is that that number is still stronger than the 1×19 wire it replaced.

Lifelines: Replace and Update

Lifelines tend to be neglected systems on most boats; if they’re brought into the shop it’s usually because something has broken, or the white vinyl covering has surpassed the disgusting-threshold.   They should be inspected and replaced as part of a boats preventative maintenance just like other bits of rigging, and the good news is that they’re cheap insurance and also a good place to improve safety and function.

The lifelines in the picture above are from a small cruising boat, and were part of the owners service schedule when he bought the boat several years ago (as a sidenote, one of the best life-easifying tricks ever is to asses a new (or current) boat’s systems and develop a multi year plan of repair:  you know what to expect in terms of spending and can spread out the projects) They are 1/8″ wire inside a white vinyl coating, with pelican hooks at the aft end,  little steel clamps to form the gate (a gate is a section of lifeline that can be released at one end without dropping tension across all the entire run of wire) and lifeline adjusters forward.  The wire was original, and the adjusters had been tightened until they had no thread left on one side.

Since they were past due for replacement,  obviously new wire was in order.  Since it was getting replaced, this was a great time to investigate improvements that could be made.

The first thing to consider with lifelines is the wire itself.  Coated wire was popular for a very long time, as it was more comfortable to touch, and looked nice (For about a season in the sun) The picture above demonstrates the big issue with coated wire.  It is prone to cracking when flexed, and when water gets under the coating it rusts the wire.  Even in fresh water this happens quickly:  stainless steel needs to be exposed to air in order to resist corrosion.  You can also see that the gate clamp is an imperfect solution when you want a lifeline gate. In addition to the clamp sliding away under load,  it also makes the wire itself the means of articulation.

Replacing covered wire with bare 1×19 wire is one of the few issues you’ll get pressure from me on.  The good news is that it usually doesn’t need much convincing:  bare wire is cheaper, stronger and will last much longer.  The downside is that it’s less flexible, and you don’t get the zen experience of watching white turn to yellow turn to brown turn to dust over the years.

The customer came to the shop looking for a better lifeline gate as well, so we were able to discard the clamp fitting, as clamps on uncovered wire are even worse than they are on vinyl coated. 

The picture above shows the old hardware (bottom left) and new hardware (top.) The clamp has been replaced with interlocking gate eyes, which are nice because they allow for more articulation of the gate, and don’t stress the wire.  The lifelines originally had 3/16″ thread adjusters in place.  The boatowner is a technically minded guy and enjoys rigging, so we made the swap from adjusters to a Dyneema lashing.  The lashing gives more range of adjustment and is less prone to damage/snagging. Of course, the line should be inspected and replaced regularly.

Using a lashing to attach lifelines also has an important safety benefit, especially for race boats.  A turnbuckle or toggle attaches to a welded eye on the pulpit/pushpit.  When using a lashing, the line can be passed through that eye and around the stanchion tube itself.  This means that instead of relying on the strength of the weld, you can put all the load onto the stainless tube.  I have been on a boat where the welded eye on a lower lifline has come free while the crew was hiking, but luckily it was only a partial failure of one weld.  The line went slack suddenly, and everyone leaned back while we figured out the issue so there was no swimming!

The last place to make improvements was at the gate fastening itself.  This boat-and many of it’s vintage-has a snap hook that is released by sliding a catch and then pulling the arm of the hook out of the body.  They’re reasonably secure unless the arm is bent. Or the catch it loose. Or the detent on the hook body is worn away.  The newer style of pelican hook (right) works just like a snap shackle, where you pull the ring to release the pin. It’s even easier to re-fasten, as you just close the hook and it latches automatically.

It’s worth taking a look at your boats lifelines to see where they are in their safe lifespan, and whether there are improvements to be made.  Feel free to contact me at or just send them in for more info and a quote.


Recovery Mode

If the picture above looks familiar, you’ve probably experienced the upper limit of a rope covers durability before!

This is an asymmetric spinnaker sheet made from New England Endura Braid Euro.  It’s a great line, very tough cover, but it still failed after just 2 seasons.  What gives?

Asymmetric sheets are very tough on covers.  They tend to have higher loads than a symmetrical spinnaker sheet, and are also trimmed more actively.  Things really get interesting in a gybe, when the line speed is MUCH higher.  In a gybe on a boat this size, you’re moving around 65′ of line every time you gybe, and the faster the better. On a boat like this with a pedestal grinder, you can pull the sheet around quite quickly, so it makes for snappy maneuvers.

What this means for the rope cover is lots of heat and abrasion.  Most assym  sheets start to feel a bit crispy in the middle, and that’s because the friction over the drums is generating enough heat to melt the cover.  The bigger the boat, the higher the loads and the more line to move, so the covers get abused more.

The solution is better covers,  specifically using heat and abrasion resistant fibers.  At the very top end we have PBO covers, which handle the highest head and load, but can retail for over $40/meter for the 10mm size. No, I’m serious, stop laughing! It gets better too, since they’ll break down in the sun and wear out quickly. Oh, and it leaves gold dust all over your boat and crew.  Anyway, the good news is there are lots of better-than-polyester covers that will cost less than a used car.  There are kevlar blends like Yaletail, and Runnertail (technically Twaron but who’s counting) but in the last couple years the default go-to special cover has been Technora blended with polyester. New England makes a rope called Poly Tec which is available as a cover or a built rope with Dyneema core.  I’ve been using this for the last 4 seasons and have been very happy with it, and have never heard a complaint about it from owners.  Marlow Ropes makes a full suite of specialty covers, but their version is Tech 50. The 2 covers are quite similar, so it usually comes down to which is available in what color first.  In addition to durability, you’re going to find that the grip on winches is more consistent, and they handle great!

So, let’s pretend your boat has taken your nice Dyneema double braid sheets and turned them into the mess you saw in the first picture. The cores are ok, but the cover looks like a shriveled churro.  We can take the cores out of the old line, and put a Technora blend cover over the top for less money than new sheets.  The cores still have a few years of life, so this is a great way to keep them going while get a nicer hand to the line and better grip on winches.

For the above sheet, the owner opted to swap both covers for Poly Tec, and gave them distinct colors while we were at it. The sheets were end-for-ended as well so the old loaded end of the sheet is now the tail and vice versa. The sheets look new, and should perform that way for many seasons.  Win!

It was a good idea in this case for a few reasons: the sheets were relatively new, the cores were in good shape and the core material was Dyneema.  If you have a damaged cover with similar parameters we can save it!  CYR also stocks regular polyester covers for a repair at considerably lower price point, although it’s worth considering why the cover failed in the first place (*usually T10 halyard with XAS clutch) It doesn’t make sense for every line though.  If the line is particularly short, the cost of labor doesn’t usually add up to less than a new line, and if the core is damaged, or Vectran/Poly/PBO it’s not usually a good idea to recover it.  If you’re in doubt, drop by the shop and we’ll look it over.  Plenty of samples to look at, and the odds are very good I’ll have rope in for the same repair to show you!

Spinnaker Sheet Y Bridle

Took these for a mail order customer who need a pigtail to add to their assym spin sheets, so figured it wouldn’t hurt to have quickie instructions for one method of setting up a Y Bridle.  This is applicable to assymetric boats only,  that have a metal clew ring or similar eye at the clew.


To start with, youll need a pair of sheets with eyes spliced into the ends (yellow), a short strop (silver) with eyes at both ends (for shackle to sail attachment) or a single eye (for tie on attachment) 

First,  attach the shackle to the strop via larks head/ring hitch/luggage tag/whatever you want to call it.  Start by passing one eye of the strop through the bail on the shackle.

Then pull the eye over the shackle

Once you’ve got the eye over the shackle, pull the line tight so that it hitches tight to the bail of the shackle and looks like the below pic

Now, put the other end of the strop through BOTH eyes on the sheets themselves

Pull the shackle through the empty loop and pull tight, should look just like this

There are several other ways to configure this setup;  you can splice the y permanently, which works the same but is marginally lighter/cleaner, or you can have 2 shackles attached to the pigtail strop, which means you can disconnect individual sheets but lose the benefit of a really smooth “y” where it gets dragged over the forestay in gybes.  Either way the basics are the same, and the goal of having the clew off the spinnaker away from the headstay is achieved.
