The Unknown Unknowns

Andy’s recent two chapters on Dux high modulus rope rigging were fascinating. He did a great job of communicating his enthusiasm, without being a fanboy blindly extolling the virtues and ignoring the drawbacks of a product, as you see so often on the Internet.

He also wrote that he would explain:

why [Dux] can be considered to have already passed John’s 20-year field test.

And that’s what I want to explore in this post. But first, understand I’m not writing this to set some young whippersnapper straight. In fact, I have huge respect for Andy’s opinions.

That said, my rule in question is probably the one that has contributed most to our track record of successful voyaging—in 25 years we have only altered, or even delayed, our plans once due to a gear failure*.

Here’s my rule:

If your primary goal is to get out there and stay out there voyaging, don’t install any gear on your boat, at least if it’s mission critical, that has not been in common use for at least ten years and preferably twenty.

As you have probably guessed by now, I believe that high modulus rope rigging (Dux or otherwise) does not pass this test. Read on for why.
