Want to rig your boat with Dynex Dux standing rigging?
See our Feb 2008 Newsletter.

Dynex Dux is the first 12 strand line that has similar stretch characteristics to 1x19 wire rope. In fact it can easily be sized so that you have less stretch than your wire rope with a minimal windage increase.
You can have synthetic rigging for about the same price as wire.

Worried about Chafe? Loggers drag logs thru the woods with it. Toughest synthetic there is.

UV?
Best uncovered Synthetic for UV resistance. At least 5 years with our Hardware (bending radius speciifc).
Our UV study will be published here soon for more detailed info. We expect a higher number.

Easily spliceable, inspectable, 1/6 the weight of wire and,
1/3 the price of PBO!



It's about the stretch...


2 types of stretch: Constructional and Material.

  1. Constructional stretch is about aligning the braids of a rope in a straight line with load.
  2. Material (elastic) stretch is inherent in the solid material properties.
Braided line has constructional stretch, unless you pre-stretch it at elevated temperatures which is exactly what Dynex Dux is. For low loads (as a percentage of breaking strength) Dynex Dux has almost no constructional stretch.?? Imagine a rigging material that you can easily splice and has low stretch properties.?

We recommend sizing line for creep at static (constant) loads, using the creep chart provided, while making sure any predicted sustained dynamic loads will not produce creep issues either. Use the Stretch information to size ilne for desired stretch. While making sure the maximum loads are not more than 20% of breaking strength.

Call or email us for help in selecting the right Colligo Dux Rigging for your boat.

The important thing to remember here is that creep has an exponential relationship to stress (Force per unit area). Keep the loads low relative to breaking strength and the creep goes way down to levels we can manage.

Example: Flying Tiger One Design sailboats have pre-tensioned shrouds to about 1200 lbs-f tension on a 1/4, 1x19 wire. You could use 7 mm dux and deal with less than 1/2 inch creep per year or go with 9 mm and have about .06 inches per year of creep on a Flying Tiger! Not to mention reducing standing rigging weight by at least 75% with most of that aloft and affecting righting moment, sailing more upright and lighter means more speed!
