4mm Dyneema Rope Options

4mm Dyneema Rope Options

Dyneema is one of the Worlds strongest fibres, it is quickly replacing wire as a lightweight option when strength is needed. Dyneema rope is sometimes called Spectra and has different varieties which have been developed over the years, SK75, SK78 and SK99.

With a dyneema rope you can expect high strength, a low weight, water resistance, chemical resistance and protection against UV rays.

At Sailing Chandlery we see 4mm dyneema being our best selling dyneema rope, it's popular across a number of sailing dinghies and is the perfect size for control lines and halyards where dyneema rope is a perfect application.

We have two types of dyneema rope available, 12 strand pure dyneema and covered dyneemas to give the pure dyneema proection. We're going to explore the options for a 4mm rope within those categores.

4mm 12 Strand Dyneema

12 strand means that the rope is made of 12 bits of dyneema rope all twisted together to form the final rope product. With a 12 strand it means that the rope is hollow on the inside and that the pure dyneema is exposed to the eye.

With the rope exposed it's easier to work with and allows you to put splices into the rope such as soft eyes. It's important to note that if you are using a 4mm 12 strand dyneema then you should be splicing and not tieing knots, a splice is much stronger and will last longer.

12 strand dyneema ropes are ideal for purchase systems, travellers, trapeze lines and lashings.

4mm Dyneema Core Ropes

A dyneema core rope does what it says on the tin, it has the dyneema within the rope as a core for strength. Quite often you'll find these ropes with harder wearing polyester covers, this is most popular on applications such as halyards and control lines which move through pulleys and cleats often. The polyester jacket will protect the core and make the rope last much longer, it can also provide more grip on the hands.

A mix of both?

There are a few ropes which can be slightly different. Take Maffioli Swiftcord rope for example, it doesn't have a core but the dyneema is built into the cover and blended with other materials to provide extra grip.

You the have the option to taper the ropes, many dyneema core ropes with polyester jackets/covers can be tapered so the core is exposed at certain points. Handy for attaching the 12 strand core and creating an eye, or for having a more lightweight rope where needed. Tapering is most popular on halyards, this would mean the 12 strand dyneema core is exposed where there isn't abraision and then the polyester jacket end can go through cleats, this would cause less friction when pulling the halyards up and down.

Credit Card Fraud Following Transaction

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.

Super gloves

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.

Mainsheet

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)

RONSTAN BUNG AND DRAIN PLUG

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.
