[C38] Dynex for lifelines?

[Max Soto]

Don, I've heard that they have to be replaced religiously every five or seven years. I saw one of those backstays fail from sun degradation. 
Regards, max

>>     When we replaced the standing rigging on Macavity we         replaced  ALL our lifelines. The rigger called them "death-lines". Our old lifelines were coated. Our new ones, conforming to the new ocean racing rules, are uncoated. The white coating can hide corrosion.  Years ago a friends wife died when the lifeline she was leaning against failed and she fell overboard during a winter trip back from Catalina. She had a heart attack in the water.   While on the subject of dead friends, my buddy Frosty, a rigger at a yard in Channel Islands died from a fall from the masthead when a wire halyard failed. I hope everyone follows my practice to ALWAYS use 2 halyards when hauling someone aloft. Joe (and happy thanksgiving everyone)

A few weeks back I noticed a broken strand in the aft end of the port upper lifeline wire at the eye that the upper gate section attaches to it.  I removed the lifeline from the boat and was detaching the cotter ring from the pin that connects the gated section of the lifeline to the long section lifeline, when the eye “fell” off the wire.  Apparently all of the strands were at or near failure.  I replaced the two upper lifelines with the thought of removing the lower lifelines for replacement next.  A couple of weeks past and a week ago I noticed that the lower starboard lifeline was sagging.  It was separated at the turnbuckle at the front of the lifeline.  When I tried to screw it together again, I noticed that the stud was broken off inside the turnbuckle.
>>> I am amazed and pleased that the lines didn’t break when someone was leaning on them.  I am also amazed that there was so little evidence of a major problem.  I would highly recommend that you thoroughly inspect and watch your lifelines if they are more than 15 years old or maybe less.  The breakage of the upper lifeline could have resulted in a fatality where the water temperature is now a brisk 49 degrees near the surface.  I hope you can learn from my experience.
