Dyneema rope has fast become the market leader for performance rope. Dyneema is an Ultra High Molecular Weight Polyethylene fibre that was developed in the Netherlands just over 20 years ago.
Dyneema is lightweight and is the World's strongest fibre. Being lightweight and strong are not the only characteristics, the dyneema fibre is also water and UV resistant.
Here at Sailing Chandlery we sell a huge amount of dyneema rope in various formats, whether that be a 12 strand dyneema rope, or a dyneema core rope with a harder wearing jacket. We stock a good selection to help you with everything from your trapeze lines through to yacht halyards.
If we have a think about where dyneema could be used on your boat there are initially two areas to review:
Think about your trapeze lines, can you replace the heavy wire with 2mm dyneema? A 2mm dyneema will come with around 450kgs of average breaking strain, plenty to hold you up above the water.
Your shrouds are the same, many pre-stretched dyneema ropes can act as shrouds too.
Also think about your shackles, probably metal and probably bouncing on and damaging your deck and boat in some areas. Our dyneema shackles are lightweight, easy to connect and certainly won't leave chunks out of your deck.
If you put a polyester rope under strain it's going to stretch. If you are using a 10mm braid on braid rope for your yacht halyard you will see around 3.7% stretch at 20% of the breakload. The average breakload would be 2,400kgs. If you change that for an 8mm dyneema core halyard rope the stretch would be 1% and you would increase the breakload to 3,570kgs with a thinner rope. Thinner rope means less friction while hoisting and retrieving your sail.
With dyneema being stronger is does mean you can work with thinner diameter ropes. Another popular thing to do is to taper halyards down to only the dyneema is showing along parts of the rope. This retains the strength you need but reduced friction where fast launches are needed.
Having less stretch in your rope will help to keep the sail where it should be keeping the sail shape leading to more speed through the water.
With just these two options you should have been able to help reduce the weight on your boat, along with the friction of your ropes as they go through the systems. We've also potentially improved your sail shape, or at least kept the sail where it should be in the gusts. This has made your boat lighter, easier to sail and hopefully faster.
We sell a variety of dyneema cord at Sailing Chandlery. Our most popular are the 3mm dyneema and 4mm dyneema ropes but we also supply dyneema from 2mm through to 12mm.
You will need to choose whether you need a 12 strand dyneema rope or a dyneema core rope with a harder wearing jacket.

Thanks for the swift completion of my order for ILCA, 2000 and Pico training sails. The material looks first class as is the workmanship. ILCA & Pico sails ordered late afternoon Wednesday received 10 am Friday. 2000 sails complete with 2 reefing points as requested made to order just arrived - delighted.
I used a particular credit card for the first time in 12 months to purchase the voucher, which an brand new email address due to work, and 5 days later a card fraud took place on that card. Fake bank employee also called me and knew the email address and confused the billing address for the company credit card eith my home address. Only one possible source was Sailing Chandlery.
Also a pair of sunglasses were not dispatched
All that I expected.
I brought the superwarm v wetsuit from sailing chandlery online. It was very quick delivery & good support for the owners.
The wetsuit is brilliant & keeping my son warm while doing his winter training.
I required 5 rudder retaining clips for our junior sail training clips, the e mail site showed the exact clips I required I ordered them and they were with me in 2 days great service I will use the site again.
Many thanks for the swift delivery of this excellent top. It is warm and comfortable and my daughter loves it. Your price was good and the service efficient
Very good price and delivery on time.
Product superb quality.
Great firm to deal with.
Very friendly and realistic service - ordered this item at the dinghy show and was told would be dispatched by Wednes latest - it arrived on Wednes!
Took the gloves on an trans-Atlantic row. Very comfortable and great when chilly at night and to keep hands dry. So impressed I’m taking another pair on my Pacific row from Monterey to Hawaii in June.
Fast delivery awesome customer service!
Great product but worth running across something across something first as is very slippy for the first few sails ( we pulled it back and forth on a smooth part of our trolley)
Very nice to pull on/off and cleats very well
Great covers and excellent fit.
Just what I needed and great service.
I've been asked to leave a review for this bung. I had bought this to give to a politician as he had requested a bung to help out with a question, but it turned out not to be the 'right sort of bung'. No matter, since luckily I have a boat and this one fitted the hole at the back and seems to just the item required for this. After inserting into the said hole, it transpires that turning it one way lets the water in nicely for the water ballast effect, and turning it the other way helps keep the water inside. Turning it again the other way then lets the water back out sometimes. It also seems that sailing backwards with the bung unscrewed is not wise but there was no warning in any of the instructions that didn't come with the product.
In summary - useless as an encouragement to politicians, quite good as a manual boat hole valve.
