If you are looking to upgrade your yacht halyards and sheets this year then you are probably wondering if it is worth upgrading and using dyneema for the ropes.
The large majority of yachts or cruisers use a double braid rope, sometimes also known as braid on braid. Upgrading your ropes to dyneema has a number of advantages which we'll explain below.
First lets look at the options and compare them.....
As we said above you might hear people also call this braid on braid, essentially the rope is two bits of rope braided together which is where it gets its names from.
The double braid rope we sell is heat set and is an ideal rope for cruising, the rope is good on hands and is also easy to splice. The two braids are a low stretch polyester core with an abrasion resistant braided polyester cover.
Dyneema cruise is made with a polyester braided cover and has a braided dyneema core within the rope. Also included is an intermediate cover which prevents slipping between the cover and core.
Dyneema cruise has been designed as an upgrade to polyester ropes because it is lighter and provides higher strength and less stretch.
In the below table we are showing the key rope data and statistics for double braid and dyneema cruise in diameters from 6mm through to 14mm.
| Rope | Diameter | Min Break Strength (kgs) | Stretch at 20% of Min Break Load |
|---|---|---|---|
| Double Braid | 6mm | 820 | 3.7% |
| Double Braid | 8mm | 1300 | 3.7% |
| Double Braid | 10mm | 2400 | 3.7% |
| Double Braid | 12mm | 3200 | 3.7% |
| Double Braid | 14mm | 4500 | 3.7% |
| Dyneema Cruise | 6mm | 1100 | 2.8% |
| Dyneema Cruise | 8mm | 2100 | 2.8% |
| Dyneema Cruise | 10mm | 3400 | 2.8% |
| Dyneema Cruise | 12mm | 5200 | 2.8% |
| Dyneema Cruise | 14mm | 6700 | 2.8% |
As you can see from the data dyneema cruise offers over 29% extra in terms of the minimum breaking load of the rope with less stretch. This means you can look at reducing the diameter of your rope which will reduce friction at every turn in your systems.
It is a higher performing rope and also tends to last longer as it has a harder wearing outer cover. The rope is also lighter than double braid which can take essential weight out of your boat, especially if you are looking for that extra knot of speed while racing.
In summary, dyneema cruise rope offers the following benefits over double braid:

Really good selection of rope sizes, delivered speedily. Great idea to put the offcuts to good use. Caused a few laughs when people realised what I'd ordered ;-)
The sales team were quick responding to our questions, dispatched to us promptly, and the product is a perfect replacement for our old tiller which ended up at the bottom of a lake!
Love the fact they don’t leak.
You do need to squeeze to get liquid out. Which is so much better. Don’t lose liquid etc.
nice size and robust
Great for when it’s not too cold. But is windy and wet. Needing to stay dry on top.
Very easy to install. May need some additional sealing for complete water-tightness.
It was time for me to upgrade to a newer Ilca and it was recommended that I get a Devoti. The price was competitive and the service from Andrew and his team was fantastic. I received lots of communication and the boat was delivered to me within 2 weeks. It is really great that Sailing Chandlery take the time to set up the rigging so that you can get straight on the water. I am very pleased with my new boat and am loving sailing it. Thank you Sailing Chandlery!
Excellent fit for a topaz. Great service on collection.
Perfect
Love this bag. Great wet area within it as well.
Excellent to use as for a birthday gift to family members keen on sailing
Currently 2 weeks into an Eastern Mediterranean trip with these shoes. Grip is great and they drain really well. Comfort is brilliant… as long as you take the right size. I followed the measurement guidelines and they work well. Highly recommend shoe!
Quick despatch and a good quality product. Moves smoothly along the boom.
Ordered a dyneema RSAero halyard on the Thursday. It arrived by mid day on the Friday and was used on the Saturday. Excellent product and service. Thank you
Reeves really easily, jams well and excellent grip
I bought the burgee and clip for a Hartley 12 and found downwind sailing much easier single handed. The clip came with the screws so it was a 10 minute job including dropping the mast. Website worked well again and the items were delivered quickly so a good job all round.
