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.

Nearly 40 years on from my first "Laser" I have just taken delivery of my second - a Devoti Ilca 7. Buying this new ILCA has been a 5 star experience, and dealing with Andrew, Jason and Steve at Sailing Chandlery have all been great - candid advice, all the help and assistance I could have wished for. And to cap it all Steve delivered the new Devoti to my home address - 5 hours away, and up in the hills, not easy to get to - and what's more Steve then stayed to help me sort out the rigging - all very different from what I remember. When I last sailed a Laser you had to lean on the boom to put on more kicker. I'm very happy to give the team at Sailing Chandlery a fulsome recommendation.
quick and easy to deal with prompt delivery on order will use again
We ordered a 100m reel of sheet rope for our sailing club's training fleet of Toppers and Fevas. It runs through the blocks very easily and is great to hold. The children on the courses love it!
Great little piece of kit, use it for giving me an idea of wind direction in the marina on my narrowboat!!
Great harness, really comfortable, looks to be good quality and well made.
Great service from Sailing Chandlery.
Delivery was super quick after bank holiday, and product is just as described. Super convenient pockets inside a comfy backpack kitbag so great and practical for walking to/from dinghy parks
Just a small item, a bung! The super quick delivery got me back on the water. Thank you.
Good rope for low load jobs - easy to splice, smooth and flexible.
Perfectly layed out numbers
WIP have really pulled out all the stops on this impact vest to suit all forms of hi-performance watersports. Feels great on, good snug fit - no restrictions to movement and doesn't impact on trapezing like a lot of buoyancy aids. A very well made, high quality vest that has everything you need to keep you safe on the water.
Purchased for my old Albacore sailing dinghy. This is a well made quality cover with straps and clips that look like they’ll last many years. I no longer have to bail out the boat before sailing!
Found the staff at Sailing Chandlery most helpful to a no-yachtsman with flags to fly to cheer the day.
It may seem strange but my husband purchased this item as he was making me some wooden bunting for our outside space. The range of colours was fab and the rope is ideal for our needs.
