Hi Steve, Dynex Dux is certified for strength by Lloyds of London. We have provided certificates to several insurance companies now and this has been enough for them.

Extrusion style furlers still need a steel stay as the bearing surfaces are just to small for synthetic fibers.

We size Dux for a maximum of 0.1 inches of creep per year, 1 inch in 10 years, not too much different than steel, depending on the type. But, you will not notice any creep issues when it is sized correctly.

When you put some thought into it, Colligo Dux rigging is really safer than steel rigging as it is fully inspectable. The only failure modes are short term, chafe, and long term UV damage. Both of these failure modes produce highly visible signs as the fibers get real fluffy when they break down. Using it does put some amount of responsiblity in the hands of the user as it needs to be inspected regularly but it is much easier to inspect. Having a rig that is almost 5 years old now I take alot of comfort in knowing that I can see all that is going on with my rig. Also, since it is 2-5 times stronger than wire in the same application, I have a considerable window of opportunity to address any chafe issues before they become catastrophic.

Splices have been around much longer that swages or swageless fittings.

A recent customer of ours with a 60' performance cat (rotating mast) in the Carribean, sent an email explaining his 4 day upwind slog in 30 knots of headwind. Here is a quote "I sure am glad I have Colligo shrouds, ss dyform connections would have been scary."
