If not mentioned already in other places: Synthetic rigging comes with a huge safety advantage: It can be cut with a knife when dismasted. A knife which should be in your pocket anyways. Dismasting usually comes with chaos in the cabin. Murphy will bury your hydraulic shroud cutter in the mess if it's not properly stored. This increases the probability of hull damage by the beating mast and boom (and a subsequent loss of vessel and life in the worst case).

Thank you for this informative video. Educational to watch. Wish you beautiful trips and lots of sailing pleasure.

for about 1 year I'm doing a refit of my 33f sailing boat on a very tight budget and being a liveaboard @ the same time makes it even more challenging but I'm getting there. And since my mast came down 9 months ago I was thinking about Dyneema Rigging, and now watching countless hr of YT videos special yours and reading a lot about it. The decision for Dymneema Rigging is done, in 4-5 months when I'm ready to get the mast up I will do it by myself even with no practical experience. Here in Germany Dyneema Rigging is not so common and for this very hard to find anybody to help or getting advice. But with your YT videos, I'm very sure I'm getting it done. Thanks a lot for this!!!

Hey Ben... I agree with you too. I mean rigging will gradually, always stretch. Especially if you've been sailing hard, or gone thru some good blows. That a screwdriver and wrench. I could re-tweak my rigging, in minutes, in a couple turns of the screw. Or unscrew it, to check it. Never had a turnbuck fail, with a little grease. I mean, synthetic lashings will fail as well from from salt drying in the fibers, and dry rot.👍

The fibers are some pretty nasty plastic fibers that will probably still be around when cockroaches inherit the Earth. I have actually seen Hayn turnbuckle screws with crevice corrosion in the threads, as well as crevice corrosion in the toggle to the chainplate. Deadeyes still have a steel toggle that can get crevice corrosion, so neither option grants you freedom from inspection! Personally, deadeyes are great if you are poor or on a really tight budget. They are inexpensive and get the job done but they are a pain in the stern to adjust! If the wallet will allow it, always choose a turnbuckle!

@@RiggingDoctor yeah...Hayne cast bronze turnbuckles will definitely corrode in salt water. Especially the open turn buckles styles, that arent barrel tubes. Ya gotta keep em greased. Every year I do a haulout, I open the turnbuckles and regrease them. I replaced all the swedged fittings, especially on the rigging lower end...as they quickly cracked in the Carib. Replaced them with Stayloc's and Norseman. I could even open them and clean em, and recaulk, or recut the cable, if needed, if it stretched. The fiber route, is less expensive, but becomes much more time intensive. And you can't open them to inspect as needed, without having to be redoing it all again.

To check for port - starboard tension equality, pluck one and if tension is close to even, the other one will resonate. Resonant frequency is a function of mass, length, and tension. Mass and length are equal. If both have the same tension they will have the same resonant frequency.

You can easily pull the end of the frapping knot through with a loop, no need for all that forcing it through with the marlinspike . Just place a loop under the perpendicular wrappings before doing those, then put the looped end of the frapping knot through the loop and pull it through under the perpendicular wraps. That is how traditional archers hide the ends of the lines used to fix the fletching to the arrow, they just don't pull through all the way.

Hello Herbie I’ve like you videos on your standing rigging. I’ve been a professional rigger for over forty years and have seen many new ideas in that time. I’m a proponent of synthetic rigging and have done a few replacements over the last few years. I like to do any soft attachments as much as possible. Please continue to spread your hard work on this subject. Let’s be professional now, on some of your descriptions of the standing rigging. Specifically what you called “check stays”. Check stays are usually attached to the runners and support the mid section of the mast when you load the runners. In your arrangement we would call them “Standing Intermediates” or “D2 Aft’s” They would connect to the mast to support the staysail. Please continue to support the good word on synthetic rigging. “Safe travels”

Thanks for the practical how to on tensioning. Very informative to see the steps and straight forward thought process. As I sit here getting ready to replace all my standing rigging with new SS and turnbuckles, a timely reminder. My big concern with synthetic rigging is the reverse ? temperature coefficient. By that I mean as it get's colder, the rig loosens up? Seems a recipe for disaster. Has this been an issue for you? Note I am on a 36 ft steel sloop, so not much flexes right now. And I will still need a SS forestay for the furler, as I recall. Seems strange to mix and match.

The negative coefficient is a bit of a pain. Our Rigging is tuned perfectly at 80F. It works great all the way down to 60F. Colder than that and we just don’t go full sail. You can mix and match fore-aft, but not arthwatship. Steel headstay and synthetic backstay work well. Steel and synthetic shrouds will make a nightmare! Due to thermal fluctuations, the mast will always be out of tune. All of the shrouds have to be the same material so that they all expand and contract at the same rate.

Once again I am impressed beyond words of this channel!

Cotter rings have a tendency to work themselves free which is a bad thing, but they won’t snag sails or lines. The first choice retaining pin is a cotter pin; but if it’s a high snag risk area, a cotter ring is the go-to (but it needs to be checked frequently to make sure it’s not working free).

There is: with SK78 it will creep back whatever it shortened With DM20 it comes out about 8% shorter than the buried lengths.

I take your point about using gauges but for a simple check or repeatability a gauge could be useful. Also for the less handy folks they have something to compare. Like if one of your chain plates is going bad or you have unseen chafe causing loosening you can have a simple way to tell. Applies to regular rigging of course too. Also I have found many people are afraid to tensioning their rig properly ( enough) leading to a dangerously loose rig in windy conditions . But I guess if your going to use synthetic rigging you will probably know a lot more........ Cheers Warren

The goal was to establish the orientation of the eye at the mast. The lowers needed it or they would rub each other in the tang, the others were just because they were already there, but they didn’t need to have them. When you re rig, the only reason you would need a toggle is because the eye would rub on something in the orientation of the tang and the toggle would turn the eye 90* and give you more clearance.

Thanks Herbie you make it look so easy. I'm tempted to try out synthetic rigging. My boat has a fractional rigging setup, what I am thinking about is where the upper shrouds passes through the ends of the back swept spreaders, how do you get by this snag. Should there be some friction at this point or can it pass through a low friction fairleed thingy... And also i have a selden mast with T terminals on both upper and lower shrouds. Have you ever seen t terminals for synthetic rigging? Best regards from Jarle

Rigging Doc. Many thanks for the education. While keeping the rig tensioned keeps the fibers moving and myself in tune with it, I’m at odds with the micro climates I experience in Northern Cal.

@RiggingDoctor

Жыл бұрын

That depends on how big your boat is. The amount of creep is relative to the length of the stay. On our rig, the mast is 55’ and the longest stay is a tad over 60’. We can see as much as 1/2” extra in the dead of winter. If the stay were only 30’ we would only see 1/4” extra in the dead of winter. I sail without issue over a +/- 20°F variance. I tune it at 80°F and I’m good from 100°F down to 60°F. Any colder than that and the rig is loose but not about to fall over. I keep the sails reefed and at 40°F I won’t go higher than the spreaders with the sails. I’m keel stepped so I always have the deck member helping hold the stick up, but being deck stepped you won’t have that. My suggestion would be: 1. Have turnbuckles so you can adjust it quickly, 2. Try and set it at 75°F on those kind of days. At 85°F it will be tight but not too tight as to break stuff and when it cools off for the night, the mast will stay up without any sails up. When your rig goes slack due to cold, all the stats expand at the same rate so your mast is still in tune (just a tad bit off to leeward while undersail) but it will still be in column. When the rig is loose, it is especially important not to have an accidental jibe as this will shock load the rig and since it’s loose, it will pick up a lot of momentum until it snaps to a halt and will most definitely break something in the process. *All of this is contingent on you having lateral spreaders (pointing straight out). If they are swept back, ignore all of this as you need to maintain 20-25% breaking strength tension on the cap shrouds at all times of the rig could fail! If you have aft swept spreaders, you need to stick with steel. If you have lateral spreaders, and do a combination of deadeyes and turnbuckles, you will be fine as long as you keep an eye on the weather and adjust the rig tension to follow it. -a trick for flipping seasons with a turnbuckle is to use electrical tape and mark the threads of the screws. Wrap the tape on the inside of the turnbuckle to mark your warm setting and wrap the outside threads of the turnbuckle to mark the cold setting. When it gets cold, you just pull the cotter pins and spin the turnbuckle until the “cold tape” reaches the turnbuckle. If it’s going to get hot, loosen it until the tape inside the turnbuckle touches the turnbuckle.

great video. my new to me small 19' boat is missing the innner stays. I thought I would use soft rigging for a try. My thought is to just use a masthead or double clove hitch at/above the spreader bar and around to the other point on the deck. what do you think?

On a boat that size, that would serve the purpose. Just make sure that the area the stay ties to is solid and will resist the force of the loop going around the mast. If the section is hollow, you could buckle the side of the spar and break the mast.

You can mix and match in that method, but when you get to the shrouds, you have to do all of them at the same time. If you mix the shrouds (steel/synthetic) you will struggle with keeping the mast in column as temperatures fluctuate. You can do all the shrouds on one side of the mast and have a steel side/synthetic side for a while until you finish the other side. That would work :) But the backstay is the easiest to switch out to start your synthetic conversion!

Hi, you are absolutely correct. Sorry to appear a smart-arse. 😉 However, I can’t help it, so here goes again. Crevice corrosion happens when the stainless is in an oxygen-poor environment, not generally the case for the rig components. With the major exception of the chainplates where they pass through the deck. I replaced all the chainplates on my 20 year old boat with nickel aluminium bronze. Expensive but I now have peace of mind. I did consider hi-mod rope for replacing the standing rigging, but decided eventually on stainless with swageless fittings. Easy with the old rig as a template, but I should not wish to have done it without that help. I find retuning the rig after re-stepping the mast is pretty time-consuming, and use a Swedish produced tension meter (about €100) to ensure correct tension. How do you do this with your set-up?

I wouldn't consider passing through a deck an oxygen poor environment. I would consider an oxygen poor environment to be keel bolts encased in epoxy. Now that's airtight! By the way he said he doesn't use any tension measuring gauges, only relies on feel. Because of the physical differences between the hardness of metal cabling and synthetic lines, I don't believe any commercially made gauges for metal cables would really function properly on synthetic rigging anyway. If you think of a steel cable under tension vs. a rope, you will always be able to pull the rope a bit more sideways IMHO.

In the situation of the pin in the tang going head up. At the top of the stay it would be really hard to install that pin the wrong way as the space between the mast and the tang is smaller then the length of the pin. So if someone managed to put it in head down they would really need to try hard to put the pin in the wrong way around. But I get it’s general advise as in some situations like a shackle that swivels up you could put it in wrong easily so head up when the rigging is in its final position or the position it will be in when tensioned is good advise.

@RiggingDoctor

I've always done it one at a time with the mast in place since the crane is expensive! There is a deciding factor in the matter: Keel stepped or Deck stepped. If you are deck stepped, then you need the stays to hold up the mast or it will fall. If you are keel stepped, then you could technically have the mast hold up without any stays on it at all. For quick connecting, I would have the lashings ready to go and simply pull them hand tight with a greater emphasis on the lowers. They will do wonders for keeping your mast up and are easier to set by hand than the cap shrouds. I would tie them all off with a series of half hitches just to make it fast. Once they are all tied, have the crane go slack on its end and see if the mast holds itself up on its own. If all is good, the crane can disconnect and you can take all the time you need to get the rigging tensioned. If the mast starts to lean really far, then the shrouds need to be tightened a bit more before the crane sets you free.

For the SK type, you want to get Heat Set (like New England Ropes STS-HSR). It happens to be SK75 but by being heat set it works better than regular SK78. If you want a more specific and definitive answer, you can email me at RiggingDr@gmail.com. I charge a consult fee of $120 and will go over the specifics that I would need to calculate the appropriate size for your rigging.

It’s called a tang and it’s specially made to mount onto the mast. The good ones are actually bolted on with a backing plate to spread the loads out better while others are simply screwed on with a flange that wraps around the spar so that the screws are being pulled sideways in a sheer force instead of being pulled off. Remember, the aluminum wall of the mast is very thin so if the forces are not well managed, the mast will tear and make a big hole to fix!

My bet is for more synthetic rigging on sailboats as time goes by. Change comes hard and this looks like a better way than stainless cable and stainless hardware. Try swaging a stainless cable at sea. Oh well I guess I'll just wait till I get to port in a couple weeks. 8-)

herb did i miss it ? what are the sizes of the deadeye line and the frapping line? dm20, sk ? i heard the stay is 9mm ?

@RiggingDoctor

Жыл бұрын

It’s all dependent on the size of the boat and the rigging loads. On our boat, the stays and deadeyes are 9mm. The shroud frapping knot can be tied in the smallest and cheapest Dyneema you can get. I switch between is 1.8 and 2.6mm Dyneema depending on which spool is cheapest. It just needs to be very small so that the turns are very tight so that friction is at its highest in the knot and the knot hold.

synthetic fibres are the way forward, so much so that ppl in that industry say that we will look back and see these last 150 years of metal use for standing rigging, as an anomaly. Dyneema will become even cheaper, is it super easy to splice, you can carry spares to do your rigging twice over if you want, way lighter, 3 to 5 times stronger than steel (for the same diameter). cons: chafe and UV. for uv you have a sheath to cover it, (in time they will be synthesizing a fiber which will be highly UV protected to begin with) for chafe you need to know your boat, so it is easily avoidable.

@benjaminsmith5433

Like, not the line you do your frapping with but the actual material that makes up the smaller line in the dead eye.

@RiggingDoctor

4 жыл бұрын

It’s a pulley system, so if you do 4 passes with the lashing, the load is spread over 8 strands. I size the thimble to fit 4 passes comfortably and the lashing material has to be at least 1/8th the breaking strength of the stay so that it is strong enough. I like to make 4 passes the minimum since the line is still small and easily worked with plenty of mechanical advantage. For heavier load stays, I do 7 passes, but using the same size of lashings as I did for the stays with only 4 passes. Basically: if you do a minimum of 4 passes, the lashing needs to be at least 1/8th the breaking strength of the stay.

That's a Phillips Spike hitch.

Two points: Most quality turnbuckles are plated bronze, not stainless. Agree on the cost factor. Second point, the thimbles used on hi-mod rope should be the closed type, not the open type use here.

@RiggingDoctor

4 жыл бұрын

The turnbuckle part is bronze, but the screws and end fittings will still be stainless steel. Ideally, sailmakers thimbles would be used because they can’t distort like these open ones can. The reason I didn’t use sailmakers thimbles all those years ago was because they were out of my budget. Five years of sailing later and my finances have improved. I’m going to be replacing our inner forestay (our only steel stay) with Dyneema in a few weeks and I’m going to be using sailmakers thimbles :)

You got to give it to the scientist the fact that they figured out how to make a plastic stronger than steel is impressive I don’t know if I’d want plastic rigging but too each his own. I guess the boats plastic too so that makes sense

@@RiggingDoctor I like your dead-eyes. I ran a freshwater boatyard for 30 plus years and have seen many many galled turnbuckles. Your dead eyes would certainly cure that! But rig tuning could get a little tedious each spring. BTW I never encountered a shroud failure in that time from crevice corrosion but then again this was fresh water. The racing guys love all this high tech line but mostly because of the light weight. My major concern would be the resistance to cutting or chafe with the highly stressed line. I enjoy your videos. Don't mean to argue, just a different point of view. Keep up the good work.

I will need to rerig it before we can launch it, and it's all the salt's fault! I wasn't arguing, I have just come to learn that there are three ways of doing things: One way, the other way, and the right way. The problem is that we only know one way and the other way!

This one was. If you didn't pre-stretch, then you will simply take the stretch out with the winch. If you are using one that is not pre-stretched, I would recommend keeping it on the winch because it will creep a bunch for a few days and if it stays on the winch, you can easily tighten it up as it creeps.

Bending the legs really far actually stresses the leg right where it exists the clevis pin and makes the leg more prone to breaking off there. The result is the leg breaks off and offers no retention for the pin. Bending them just 15* gives enough retention without stressing the metal in the cotter pin.
