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:

Ordered Harken xd kit from another chandlery but didn’t include this vital piece of kit. Thank you for quickly sending this piece of kit so quickly.
Comfortable but with enough grip so they feel like they'll stay on in a capsize (although I haven't experienced that yet). The lenses are good quality with no distortion and the price was really reasonable. Service from Sailing Chandlery was exemplary. Very good value.
Makes a more secure anchorage than a stopper knot
A stock of rope and cordage is essential for the proper function of any sailing club. Floating and non-floating rope are needed equally. This is a good product, at a reasonable price - if bought on the reel.
My first Zhik spray top, but just like the rest of the gear from Zhik the combination of design, material selection and style are spot on.
I’ve been wearing the top in the Dragon, Edinburgh Cup where there has been a rain and significant spray at time. The top has kept me warm and dry. Especially impressed with the neck seal. Dry, yet not constricting.
Boots arrived quickly and were a great fit
Very Good A+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Service excellent as always . The pads are great for laser sailing
Great
Just what I was looking for, good to be able to buy any number of toggles I needed.
I bought some kingfisher spliceable rope to replace a continuous control line. It's an easy splice and that's down to the quality of the rope supplied by the Sailing Chandlery.
Great
It’s a nice halyard thing and strong, and looped through itself it has a slim profile. Also I need extra length and sailing chandlery where happy to add it on for me! Greatt!
A perfect match, installed and working well.
I do wish there was a less expensive shipping alternative for your international customers.
great products , great service
