Creep in Dynex Dux

[jfranta]

So let me ask my key questions, because any further analysis depends on this:

*** Is the graph of creep data for Dynex Dux rope previously posted on the Colligo site reasonably accurate?

*** Also, is the equation that was overlaid on that graph reasonably correct for Dynex Dux rope applied to rigging, insofar as it represents the creep rate as a function of load and temperature?[/quote]

Yes, the graph of creep data that was previously posted on our site is correct and references were listed on the graph. I can supply these if requested. The stretch numbers are correct also being verified by external sources.

When I first started advocating Colligo Dux rigging my first approach was to have graphs and charts in my booth. As an engineer, I am a big advocate of data. I even had a large easel at the Annapolis show the first year with several big posters of data in chart and graph form. I still have this in my office here. 98% of the people that I tried to get to look at the data lasted about 30 seconds before their eyes glassed over, including most riggers and even some well known boat designers, who we consider our customers.

From experience, we have found that it is much safer to work with individual customers in their specific applications when working out the sizing.

In addition, we have found several repostings of our data in various places on the web where we were not referenced and our competition was even recommended so there is also a proprietary reason for not keeping all the information posted. We are in business to make money. I am sure all can understand that. Again, we are willing to work with all on an individual basis.

We, at Colligo, will do all that we can to get all the data out on our products and, I believe that when you compare us to the other synthetic rigging options that you will find much more information from us. Just try to get info on PBO rigging from the manufacturers.

The internet is also a good source for any info on Gell Spun Ultra High Molecular Weight Polyethylene (Dyneema or Spectra).
