Are you sure you got a real rigger?

Or one that is aware of what can/cannot be seen on a failing swage.

Did he recommend using a magnifier?

Freeze thaw cycles are just as hard on the rig as salt exposure. You may not be able to see the micro cracks at all unless they're being pushed open by frozen fresh water.

The more I'm reading your posts, in that thread or in others, or your blog, and seeing the pictures, the more I'm convinced neither you nor your boat are ready for this trip offshore. Every time somebody give you the sound advice to postpone until you are ready you are putting your head in the sand. Are your kids coming with you? I suppose so. Don't play with their lives. For their sake don't do it. Please.

That only reveals broken wire strands, or fish/meat-hooks.

I estimate that in the past 10 years use my rigging has the equivalent of 173 of 24 hour days use. And I bet 75% of that is in wind less than 15 knots. Compare that to loading and time on the cables in the average suspension bridge and I just don't feel my rigging is in a lot of danger.
I agree with this ,I fly hangliders that are 30 yrs old at "the classic" every year and I have had no problems with cables "letting go",as said before check them over and if they aint broke they will most likly be ok,maybe ,perhaps,should be (but who knows?)

Re: How can I be sure my rigging is good?

To be completely sure that your rigging is good on an old boat, you need to completely replace everything including the chain plates. If you have the skills, do it yourself and verify that the materials that you're using is up to stuff. Anything less than that and you become less certain that the rigging is good to go. Proper inspections can take the place of a complete retrofit, but you're loss a little of being absolutely sure that the rigging is fine. Defining a proper inspection is problematic.

Do your hang gliders stay outdoors, live in a salt water / salt spray environment, and undergo continuous cycling/shock loads and occasional freezing cycles? That might make a difference.

But I do agree that the "ten year rule" is probably overly cautious in most cases.

Re: How can I be sure my rigging is good?

I could see the pvc being a pretty good protective device. There is likely plenty of afresh ir in there to avoid crevice corrosion and they generally keep the water and salt off.
You just have to do the best you can and go for it. I can think of a couple of boats with new rigging that broke shrouds in the first couple years off shore... so nothing's perfect...

Re: How can I be sure my rigging is good?

Still don't know if the boat has seen much salt water however, for peace of mind Scoob, I would have a die test done and if the rigger is over 30yrs old I suggest he uses a magnifying glass. Might also need to probe inside strands.

Re: How can I be sure my rigging is good?

Scoobert is at it again...........he asks a question (how can I be sure my rigging is safe), then proceeds to tell everyone that has constructive advice how he is sure that there is no problem. This has happened in several post that he has made. He asks in another post as to how long it will take him to go from Albany,NY to Miami ,FL. Much advice (almost 300 total posts) and he is sure it will take him only 5 to 7 days!!!! He is a master of asking a question, and then telling all that give him sound advice that he knows better.
