Dyneema and Spectra

According to Wikipedia, “Dyneema® is a registered trademark of Royal DSM NV (The Netherlands)” and “Spectra is the brand name of the chemically identical product developed independently by Allied Signal (now Honeywell) in the USA. Though the production details will undoubtedly be different, the result is comparable to Dyneema.”


In the end I rang a rigging crowd in Sydney, who advised that the product below is what they use for trap lines on the Sydney Harbour 18' skiffs. Having seen these boats I decided what was good enough for them was good enough for me.

Splicing this stuff is a cinch, and @ AU$2.73 a metre seemed like a good deal.

Check out the breaking strain below.


DYNEX 75 3MM HRL-130


* Price per Metre
Dynex ropes are impregnated with Duracoat to improve abrasion resistance and endurance. It has neutral buoyancy (ie. it floats) and low diameter to strength ratio. Dynex is made form Dyneema SK75 fibres with a polyurethane coating. These ropes combine good strength retention with good flexibility and dynamic properties. Termination is easy through splicing where up to 90% of linear strength is retained. Dynex ropes exceed the strength of steel wire ropes of the same diameter while floating on water. They have low elongation and are extremely flexible, yielding easy handling in all respects.
