FINALLY we have made a video about our synthetic rigging!! This is one of the things that sets us apart from other sailors and we love the system that Herby has set up. Learn all about how to tension it and travel up the mast for a full view of how it works as long as both pros and cons that come with the decision.

Love the concept. 15x stronger than steel, 1/5 the weight. 30 years as a rigger and charter captain but retired since 2000, so totally out of the loop on new innovations. But still sailing...:)

Great video. I was just sailing in 40 kt winds. the wind was so hard that the lee side spreader actually popped out of its housing and was lost. We didn't know this until we came about and nearly broke the mast. I have a 30 ft C & C. When we came about we noticed that the top of the mast was bent nearly 4 feet off center at the top. We quickly did a straight downwind sail to take the pressure off the mast, dropped the sails and connected the main sheet halyard to the port side rail to stabilize the mast. After we assessed the problem we realized that the set setscrew that held the port spreader failed, and the spreader got yanked out of its housing. Design not so good. A learning experience. Thanks again. Steve.

@pentachronic 5 жыл бұрын

This is where dyneema is better IMO. It has less points of failure. As a climber, I use lots of different cordage and one thing we ALWAYS do is plan in redundancy. Now since dyneema is relatively cheap it might be possible to make a shroud that has 2 parallel dyneema cords that are tensioned appropriately. If one gets severed the other can take the load. This might be an overkill though as dyneema is stranded. But I’d love to hear thoughts on this. Wind will likely whistle through the 2 strands though !! My thinking is that you might be able to shrink the diameter down of the original by 1mm and then double it up. This would provide redundancy and make it cheaper (prices is a square law of diameter).

One question I have are related to the tension which must be achieved: did you use any measuring tool and which one? Wish you both fair winds and safe sailing

@RiggingDoctor 4 жыл бұрын

I set the tension “by feel”. Basically you want the shrouds tight enough that the leeward stays go slack but not loose. If they go loose, you need to tighten them. If they stay tight, you need to loosen them.

Can you use a rigging tension gauge like the loos? In a hi performance trimaran I raced on 20 years ago we had Kevlar/technora stays with shrink tape/tube uv protection , not needed with dyneema/spectra but it could be useful for chafe? The dyneema splices don’t appear to hold very tight on the SS thimbles. Is their anyway to improve that . I have used a adjustable technora back stay for years but for quick adjustability for different wind condition ( I race) means I would want to use turnbuckles I think. Definitively a flexible system for maintenance in far flung places! Cheers warren

@RiggingDoctor 6 жыл бұрын

You certainly could slip a shrink tube over the stay to help with chafe protection. The eye splices are a little loose to facilitate thimble replacement and because the thimble is not present when the splice is made, making it hard to make it snug enough without making the eye too snug. To tighten it up, you can tie a seizing knot at the throat.

@richardbohlingsr3490 4 жыл бұрын

TFS well presented and I think most can understand what your doing with the rigging. One question I have is can you use a self furling jib on the forestays or will it abrade the dyneema. The way your setup to handle lines from the cockpit would lend itself to having self furling on both jibs. I do thing the weigh loss with the dyneema is a good way to lower your center of gravity.

@RiggingDoctor 4 жыл бұрын

The furler can chafe the Dyneema and there would be no way to inspect it. As far as I know, there is still no furler over Dyneema.

Fantastic informative video. We've had some rod rigging repairs carried for the reasons you mentioned. didn't even consider Dyneema.. We will next time, if only for the weight saving. Have you ever had Dyneema shrouds fail catastrophically. What is the breaking strain compared to stainless steel and rod rigging. Very good review, well done.

@RiggingDoctor 5 жыл бұрын

I have never had a catastrophic failure with dyneema. Off of Hatteras, our anchor chafed on the headstay deadeye and sawed through a few of the strands. We knew it was crippled and kept the loads to a minimum on it. I consider that chafed headstay a failure because we couldn't use it like normal, but the stay never broke and nothing fell down, so I also consider the whole situation a success. Chafe is very easy to spot as the line looks visibly worn and fuzzy, whereas steel has a microscopic hairline fracture. Thanks for watching and let me know if you ever have any questions in the future! P.S. We will be doing a video soon on spotting and repairing failing dyneema. One of our lifelines is in need of some work and we will be covering the whole process. Be sure to subscribe so that you are notified as soon as it's uploaded.

Ziya Aslan fore aft stays in different materials works fine. There will be different expansion but it can be adjusted by tightening or loosening the backstay accordingly. If you mix and match in the shrouds, the mast will always be out of tune. The lateral stays need to be the same material while the fore aft stays can be different.

@kimyoung230 5 жыл бұрын

Thank you for the video! Very helpful!! I would like to use synthetic rigging when I replace my standing rigging on my Sabre 34 in the next couple years. I have a couple questions. When you adjust tension on the caps, do you need to temporarily remove the spreader tip lashings that keep the cap from moving and chafing on the spreader tips? Also, do you find that you adjust tension on caps/lowers with this process less frequently than if you just have a turnbuckle to turn? Any reason not to use a turnbuckle in place of, or in addition to, the deadeyes at the chainplates?

@RiggingDoctor 5 жыл бұрын

When the rigging is new, I don’t seize the spreader tips because as I go taking out the stretch, the spreaders would get pulled down, and I need to go up and tap them back into place. Once the stretch is out, I then seize the tips to prevent any movement or chafe. The amount of adjustments are the same, turnbuckle or deadeye. The difference is a turnbuckle gives less distance that can be adjusted, is heavier, and is much more expensive, but adjustments are quick and easy. A deadeye, is lighter, cheaper, more lenient in the distance it can be adjusted, but it takes a lot more time to carry out the adjustments.

@RiggingDoctor 5 жыл бұрын

I chose dead eyes because they make fabricating the rigging easier (measurements don’t have to be as precise since the lashings give you more leeway) and they are cheaper. $24 in materials as opposed to $100 per turnbuckle!

@davidross5291 2 жыл бұрын

When you spliced your stays, did you need to pre-tension the stays to set the splice? I'm reading where I might need to apply 2k lbs or more to the stay to 'set the splice' before using. What's your experience with this? Also, any tips on getting around t-ball fittings?

@RiggingDoctor 2 жыл бұрын

This is a post about the cost of conversion but it was on a bot with T-balls so it goes over all the added pets needed to make it work on the mast side of the stay. As for setting the splice, you don’t have to but it will save A LOT of time. If you don’t, you will be taking creep out of the line for about a month. If you set the splice, it becomes just a few weeks and very minor during that time. To set splices, I attach the stay to a tree and the other end to an old F150, then I drive away from the tree slowly until the stay goes tight and the truck stops. I measure on the ground where the tires meet the ground and do this until the tires stop advancing. Then I leave the truck in neutral on a hill held up by the stay and tree. I leave it like this overnight and come the next day it’s pretty much done creeping.

the german yachtmagazin palstek.de had a nice article on the topic dynema rigging. You might get big problems with the peak loads at the points where you fix the dynema to the boat. the 7x19 stainless wires usually used have a lot of strech when there comes some power to the boat. You would never ty your boat to the dock with dynema because you might lose your clamps when some heavy swell will move the boat. you will use some polyester with 10 -30 % stretch to cut of the peak load. the palstek rigg doctors recommend to strenght the points of fixation the dynema a lot !!!

Shrouds will give me the precision I need. Could I use turnbuckles to tension all of the rigging like you did to your forestay? Your opinion is much apreciated. Thank you in advance.

@RiggingDoctor 5 жыл бұрын

Turnbuckles can certainly be used and will make the process of tuning much faster and easier. The reason I didn’t use turnbuckles is because they were out of our budget, so this helps show a way that it can be done without turnbuckles. With turnbuckles, you either get your splice perfectly measured so the throw of the turnbuckle is sufficient, or you simply cut your stays shorter and have the lashing and deadeye which attaches to the turnbuckle. The latter arrangement makes the construction process much easier since the lashing will correct any inaccuracies in the length measurement. You could think of the lashing as the macro adjustment and the turnbuckle as the micro adjustment.

Is there any particular reason you don't use turnbuckles so the tension can be adjusted quickly and easily with any change in temperature? Tensioning the rigging using the winches and frapping knots seem very time consuming.

Turnbuckles would be nice, but we needed 11 of them and for our size, they cost around $100 each. To save on the cost, we went with deadeyes which cost about $24 in materials.

Hello. Super video, and synthetic rigging will be perfect for me on my next "old" boat. Very informative and good video. Only one question, why not "turn buckles" on all lines to tighten them. Is it just a cost issue or are there other considerations. Hope to hear from you. Norway.

Just a cost issue. For my size, they were $100 per turnbuckle where a deadeye was $24 in materials. With 11 turnbuckles, the choice was simply based on costs.

To make them for turnbuckles, your measurements and calculations need to be 100% perfect. I did that with the headstay and most of the fabrication time was spent counting threads to get it perfect. Then you have to get all the stretch and creep out before you install them. This can be done but it is labor intensive and needs some hefty equipment (or a tree on a hill and a heavy vehicle to hang by the stay for a few days while the creep occurs). If you have dead eyes above the turnbuckles, you have more flexibility with lengths and you can get all the creep out on the boat. The dead eyes take out the major stretch while the turnbuckles do the tensioning.

Would you be able to mix/match synthentic with steel standing rigging? For example, replacing the lowers with synthetic, while leaving the uppers as stainless. Or replacing the shrouds with synthetic and the fore/aft stays with stainless? I replaced my lowers last year, but the uppers were swaged in place and I couldn't take them off without cutting them. I would consider replacing the uppers with synthetic. My forestay requires a metal stay for the roller furling that is presently in place, so I probably would stay with the same. But my aft stay could be easily replaced with a system like you mentioned. Is it fine to mix/match or are there some other considerations that I should know about?

@RiggingDoctor 4 жыл бұрын

The headstay and backstay can mix and match, but shrouds should all be one type. Synthetic and steel expand differently as temperatures change. Your mast will only be in tune if it is the temperature you set it at. This means you would need to tune the Rigging every time you went out because of temperature changes. If they are all steel or all synthetic, then they will all change the same with temperature and the mast will remain in tune.

@@RiggingDoctor Thanks! I'll consider it as an option! I think it will be a good match for my Contessa 26. As boats get larger, are there limits to when synthetic stops being appropriate?

Great video very informative. I notice you use "standard" Thimbles on your rigging, my question is was this a purely economic choice or would you have chosen the cast polished thimbles given the choice thanks

@RiggingDoctor 4 жыл бұрын

It was based on cost. The regular thimbles cost me $1.50 each where a sailmakers thimble cost me $12 each. The regular thimbles crush down until the ends meet, then they stop closing. They work well unless they are hit hard from the side and cause the ends to slip next to each other. Under the tension they hold, the thimble buckles and crushes, then needs to be replaced. A sailmakers thimble would be far stronger and safer, but cost significantly more where I was when I made the rigging.

Could you skip the toggles and go directly into the tangs? If so it would save even more weight at the top of the mast where it has the most effect on heeling. Cons?

@RiggingDoctor 5 жыл бұрын

Yes, but the tangs for the lowers are close together and the eyes would rub. The toggle simply flips the eye by 90*. The toggles at the top are not necessary but they looked a little less “chafey” than the tang of the eye were to ever rub on it. In steel rigging, the toggles are mandatory because they provide a universal joint at the end and greatly reduce the incidence of stress fractures in the end fittings and wires. Dyneema won’t fracture, so it’s more focused on space. 1/2 a pound at the top of the mast is about 25 foot pounds on a 50 foot mast, so small numbers can make big differences! Definitely try to use the least amount of parts that will safely accomplish the task at hand.

Hello guys!, thanks a lot for this informative video! (I understand its 3 years old by now btw). Two questions: 1. you mention you have to service the spreaders protection; so..How often do you service the dyneema protection in the spreaders?. The second question: It is my understanding that Dyneema gets degraded with the sun light; how do you guys deal with this; would it make sense to cover somehow the rigging to protect it from UV lighting?. Again, many many thanks! :D

@RiggingDoctor 2 жыл бұрын

Hello! While it’s an older video, it all still holds true. Service is when you wrap another line tightly around the one doing the work. www.riggingdoctor.com/life-aboard/2015/9/1/line-service I haven’t had to do anything in those areas and we’re entering the 7th year now! As for UV, yes and no. The outer 0.1μm gets destroyed and protects the rest of the line, so there is no loss in line strength and it’s easier to inspect without a cover hiding it.

Rigging Doctor I wouldn't mix steel and dyneema rigging because of the different elasticity properties of the two materials. Personally I would stick with the dyneema and wrap it with kevlar for the length needed to prevent chafing. The kevlar string will ruin a pair of scissors trying to cut it.

Actually Brent, the thermal expansion difference isn't such a big deal in practice. We have all synthetic rig, except the two headstays. It all functions exactly as required, I havnt touched the tensions for 6 months, despite a temp difference over that time of up to 40C. The only difference we notice is the tune of the rig hum when the wind blows through it.

They have been 7 years and thousands of miles. This rig is actually the prototype for synthetic rigging. When I made it, I was told by Colligo that it couldn’t be done on a boat my size with deadeyes. The reason those are not fully seated is because I was testing the bury portion to make sure it would hold appropriately. If the bury ever slipped, the lock would close and take the load and I would know that the bury had slipped and should be even longer. As you can see it has been holding up for all these years and never budged!

@RiggingDoctor 6 жыл бұрын

1. I already had the bronze toggles on hand. 2. It gives full range of motion to the top of the stay by creating a universal joint which lowers the stress on the tang. Being rope rigging, this isn't as necessary as the rope itself has flexibility. Since I already had them, i decided to use them. 3. The lowers needed the toggles to make everything fit closely together without chafing. For the sake of symmetry, I did the cap shrouds with the same setup as the lowers and check stays.

So it's no good in the winter unless you somehow make it work.... what is the UV rating?

Interesting concept the synthetics.... still some kinks to work out.

@RiggingDoctor 5 жыл бұрын

Yep, winter stretch is pretty intense. The Rigging goes slack in the cold and comes back to tension in the spring. If it’s too cold for the Rigging it’s too cold for me! UV resistance is fine, DSM has found no detrimental effects of UV exposure to uncovered Dyneema. The truck and tree method was me on the blog, also a few of our early videos (I don’t know if those early videos are still public though)

I like the idea for the weight saving and also it looks great to use something with a more traditional look, but I want to keep things simples. Any technical problem doing this?

Turnbuckles are wonderful, they just need to be inspected (just like deadeyes) to make sure they are in working order. The biggest reason I didn’t use turnbuckles was cost. We needed 12 turnbuckles (at $100 each) which would have cost an additional $1200 to re-rig the boat. I was trying to do it in the most economical way possible, so I went with deadeyes which cost $24 in materials. I personally and currently have two turnbuckles (one on each forestay) to make life easier, but the rest are still deadeyes. If you can afford turnbuckles, I would use them in a heartbeat as they will make adjusting the rig so much easier! If you are trying to save some money and have lots of time on your hands, deadeyes are an option available to get you on the water for less money.
