Re: should I replace my standing rigging myself
Farr? Actually, the topic was originally about replacing shrouds- I was just correcting what I had originally suggested. I have no idea what the load is on my backstay, because I've never measured it. It's gotta be huge, though- 48:1 on a double spreader rig. The size of SK75 is indeed 7mm, and there definitely is a small amount of creep, since I can now easily reach the thimble with the backstay cascade that I regularly connect/disconnect when hoisting the boat out of the water each time we sail. I'm guessing the creep is minimal- probably about 1/2" (guessing) for the 30' or so of Dux that goes up to the masthead crane. I've sailed quite a bit in the upper medium wind range (my own term, but around 15-20 mph) and store the boat with the backstay tensioned about 50% to steady the rig- the idea being to get the system to completely set itself. I've already had to shorten one of the braided dyneema lines in the backstay cascade, and I'm about to do another to regain purchase that was lost in dyneema stretch as well as that tiny bit of creep further up in the Dux. My point was- that if he uses Dux (or NE's version of SK75), he avoids the cost of all those fittings (which I just replaced on my own boat this year- they are the main cost of replacing standing rigging), then he could use Dux-- he'll just have to adjust it after a few times out. On a 26' boat, that is an attractive alternative and I'd probably consider it for lake sailing.
