Just out of curiosity, where would you want to use a soft shackle?

Use it to attach a block anywhere where you need a little more freedom of movement than a steel shackle provides.
Spinnaker or jib sheets with eye splices in them.
I leave one attached to the end of my boom for the halyard to attach to (in lieu of a topping lift).

OK. Thanks for the quick reply. I had heard about putting them at the jib sheet ends. I currently use a single jib sheet with a cow hitch in the middle. Soft shackles better?

I'm a fan of bowlines honestly... but that's a conversation for another thread.

I like the cow hitch too... makes the jib clew slide over the stays'l stay easier than a bowline would.

I could however see using soft shackles for blocks to change the lead angle for the jib sheets. Seems like a great use.

If you don't need to remove or change the jib sheets often, I can't see anything easier or better than a cow hitch. That is what I've always used. I guess the downside is that if you ever chafe or damage one leg, you need to replace the whole thing.

Like mentioned earlier, we also use a soft shackle to connect our bridle to the anchor chain.

Dyneema is more abrasion resistant than high carbon steel. One of its common usages is in chafe protectors for other rope types - also in cut and abrasion resistant gloves. Our shackles show no wear after a year of dragging through sand and rubble. If we regularly anchored in sharp rocks or coral (who would?), then I might have more concern. Even just cutting this stuff is tough to do - I keep a special ceramic knife for this purpose (cuts it like butter). A regular steel knife needs to be sawed back and forth and the dyneema often frays as it cuts.

But the thing to remember is that a soft shackle costs $1 and 15min of time. I keep several around and can just replace one at any sign of weakening, or just on a routine basis.

Thanks Mark. I was just thinking of adding an "emergency" anchor on my stern rail but didn't want to leave the chain and rode attached because I have no easy way to get it into the lazarette and don't want to put more holes in the boat. A simple soft shackle would be a very quick way to attach the rode and deploy the anchor in an emergency.

To clarify, we use a soft shackle to attach our bridle (snubber) to the chain - not to attach the chain to the anchor.

However, quickly attaching the rode to the anchor in an emergency situation like you describe would be fine, although I would consider that a short-term usage only.

Hopefully any "emergency" requiring a quick deployment of the stern anchor is short lived! I would have a standard shackle on the anchor in the event my emergency wasn't quite that time critical. Thanks for the input.

I've been practicing soft shackles with various line I have but want to make some for real now for Code Zero blocks. What size line and type should I order to start making a few?

@JRT... here are some ideas.
The soft shackles are beyond strong enough. You can use different dyneema line diameters. The last one pictured is tested to exceed 10,000 lb breaking strength. More than most boats might need. The design breaks at the point the knot goes against the loop. In the design the dyneema is double strength for both loops. Design is Brian Toss's

I assume the blocks you are implementing are to turn the sheets. If so this is an interesting product I came across. Notice the side load capability.

Thanks all, those links are helpful for sure. Looking a bit into this more I think I'll use 3/8 Sampson Control-DPX from the SBO store, any feedback?

JRT that will make a very strong shackle.. Use a 50” length of to make your shackle. It will be a good length to teach yourself the knot. PM me if you have any specific questions.

I use them for my change in direction blocks for my genoa and some other rigging attached to my toe rail. I also use a splices ring to attach my main sheet fiddle block to the traveler car. I have a handful of different sizes tied up and ready to go. Very handy and strong and very replaceable.

For splicing dyneema, ask a welder friend for a piece of stainless TIG wire and bend it in half to form a wand. Maybe get a thick and thin piece of wire for different diameter dyneema. To use, just slide the bent end down the splice from where you want the dyneema end to exit toward and out where you want the dyneema end to enter the splice, pinch the dyneema end in the bent wire loop, and pull through. Easier than trying to push a fid up the splice with the dyneema end taped to it.

3/8" will make a thick shackle (and way overkill in strength), so make sure it will fit through what you want it to attach to.
