DYNEEMA [Part 1]: Replace Your Rigging | Sailing Wisdom

[@braithmiller]

Finally going Dyneema forstay? Good explanation there. Like it when I can say watch you rather than me explaining it. Anyone want to add? Top ten ways to know your standing rig needs replacing: Mast is hanging off in the water. Furler is a wrecking ball. Mast is now topped at spreader.

[@robw2379]

Great video. Lots of sailors assume that stainless steel == good forever, which is of course untrue as you point out. I remember you discussing stainless rigging age & insurance issues in a previous video, and I think you said that your boat is uninsured by choice. I would love to hear about insurance implications of a dyneema rig, insurance decisions in general, and your thoughts about when to get/skip boat insurance. I think boat insurance is in general a very murky topic for novice sailors. Thanks again for the great vids! Stay safe. 😀

[@RiggingDoctor]

That would be a great topic for a video! We have liability insurance only on our boats. Insurance doesn’t shy away from synthetic rigging as long as it’s under 10 years old for the most part.

[@jonathanoasis]

my boat insurance company didnt seem to care when I updated my policy to state that I had synthetic rigging. i dont think it made any difference in the premium cost either. I am forced to have some policy like $500,000 in liability insurance because my marina demands that for every slip owner. the marina doesnt care (but they should) what kind of rigging anyone has either, the only thing they care about, is if you have 2 fire extinguishers (which are nearly useless for any sailboat fire) and flares (also useless in an emergency) and life jackets etc.

Oh that’s some good info you two. Just fir the hell of it I’m going to inspect the cabling I just replaced with dyneema to see if I can spot more things on them. Question though. Being that’s your stay and you got your jib on there will it be possible to use dyneema fir that

We do but the stay needs a chafe sleeve to protect it from chafe caused by the hanks.

Thanks Herb, was soon as my knee gets better I'll do a complete inspection of my stays. Also wouldn't it be a good idea if when replacing or new stays to put some kind of sealer at those spots where the cable and fittings.

On steel, yes. It keeps out the water which makes it last a bit longer

[@hyperfilmprod]

This is very helpful, thank you for this! Did you replace this stay with dyneema?

[@RiggingDoctor]

Yes indeed! When I bought the boat, the inner forestay was brand new so when I converted all the rigging to Dyneema, I kept this one to help reduce the cost. When we were in Spain, the steel stay died and needed to be replaced, making it the last stay to be converted on the boat.

I just bought a 1985 Nauticat 44 boat. It's a ketch. The rigging needs to be redone. I'm considering Dyneema (because of your videos...).

Please send me an email with your questions at [e-mail] 😊thanks

[@joewalsh7656]

Great videos I am close to the 10 year mark on my steel standing rigging on a gaff cutter. LWL is 23.5 feet, and the length of spars is 32 feet. The current wire is 6mm. What yound you recommend in dynmea? I was going to start with my runners. Thanks in advance.

[@RiggingDoctor]

Dyneema will be great for you. Gaff rigs have really low tension at rest so they are easy to setup and adjust with Dyneema. You will love the stuff!

[@joewalsh7656]

Do I match the wire size with dynmea size ? Or Air on the side of caution and go a size up ?

[@RiggingDoctor]

I look at the equivalence to make sure I’m not going weaker than what is there, but then I do a bunch of math to see what size it really needs to be. I use the RM30 to figure out the force exerted on the rig and then a few other formulas to figure out the static load on each stay and therefore determine the appropriate line size based on strength. Most of the time, it comes out to be near the size of the current steel but I have had a few cases where the boats original steel rigging was undersized and swapping Dyneema size for size would have led to some problems with creep.

[@TarasKalapun]

would you replace the compression fittings (StaLocks) same time you replace the wire? Like every 10 years?

[@RiggingDoctor]

If they are still in good shape, you can reuse them. Those fittings are the best way to go when building steel rigging

[@monaghanpete]

Amazing tutorials as always, PMSL at the pronounciation comments, whats wrong with people, what is your prefered brand of Dyneema for standing rigging?

[@RiggingDoctor]

The manufacturer has to be DSM, the others are not as good of quality. Marlow sells one called DM20 that is amazing but expensive, whereas New England Ropes sells one called STS-HSR which is heat set SK75 or heat set SK78 which is really good and a lot less expensive. The heat set creeps a little bit and is stiff to work with but it gets the job done. DM20 is so soft in your hand and doesn’t creep at all, it really is amazing!! Marlow DM20 or New England Ropes STS-HSR are the two brands and models to use.

[@vaidotasratkus7619]

I live in Norway, temperature can change 10degrees in 24 hours, can I use dyneema? Or I will need to retention it every time I go sailing?

[@RiggingDoctor]

You would be at the limit for what I am comfortable with. We sailed with the same tune all the time, and the temperature range was from -6°C to 43°C. If it was between 38°C to 15°C I didn’t worry about the rigging. Less than 10°C I would keep the sails lower on the mast (stay reefed instead of full sail). Less than 4°C, I wouldn’t put sails higher than the first spreader. This worked out well for us and our relaxed style of sailing. We also have lateral spreaders which accept being loose much better than aft swept spreaders which MUST maintain a high tension at all times or the mast could invert and break! It depends on many factors, but if your spreaders go straight to the side and don’t sweep backwards, then you will be fine. Just give the rigging a jiggle before you sail and act accordingly to the tension. If it’s tight, go full speed! If it’s loose, take it easy and don’t crash gybe.

[@vaidotasratkus7619]

@@RiggingDoctor perfect answer. Thanks

[@jacekcentkowski979]

You can always use a bucket to keep afloat but you can’t lean against the mast to keep the sails flying.

[@lenwhatever4187]

So why choose a stayed mast? It would seem an unstayed mast might be a better deal. Oh, I understand that if the boat came stayed, changing is not easy, but why stayed in the first place? The only place it seems to matter is racing where an unstayed mast dings the rating adversely. For that matter there is yet another option of lightly stayed where the mast is designed to be unstayed but has "loose" stays to help keep the fore stay taught should the vessel have a fore stay. (The Gazelle is loose stayed for example) Aside from that, why stainless? considering how long stainless wires don't last, why not use galvanised? Work boats do. But you will use synthetic anyway I guess so not an imortant consideration. :)

[@RiggingDoctor]

Unstayed vs stayed masts really depends on what the boat is designed for. In a perfect world, all bots would have junk rigs, but the vast majority don’t. I prefer galvanized over stainless for rigging, but I prefer synthetic for its ease of setting up and fabrication. You can splice braided wire, but it will hurt you where splicing Dyneema is actually fun! A well maintained galvanized rig will outlast a synthetic and grossly outlast a stainless rig, but the maintenance is messy. For that reason, I like synthetic on my own boat.

Great stuff! A linguistic aside: In former incarnations re US Navy propulsion/industrial construction/electrical power generation/petrochemical industries trades, we were taught to pronounce 'Swage/swaging' *sWAYj* and *sWAY-jing* - I'd not heard it pronounced 'swahdj/swahdjing' until this evening.

YOU HAVE A BIG PROBLEM!!! NEVER, NEVER, NEVER PUT COPPER AND STEEL TOGETHER (YOUR BRASS SAIL CLIPS). YOU WILL GET COPPER PITTING CORROSION ON THE STEEL.

[@RiggingDoctor]

Copper and steel are an issue but bronze and steel pair well together. Think of your prop shaft (stainless steel) with the prop (bronze) bolted to it. In a relatively dry environment like a stay, there is no need for electrolysis collars, as the bronze hanks will grind away faster than they could corrode. In this setup, there is no copper, everything is bronze or stainless steel.
