A friend who has circumnavigated several times has rerigged his 39’ steel cutter with Dyneema for the shrouds.
Very strong, light, straightforward to splice. Definitely DIY. And having extra material aboard to make emergency replacements for rigging is very easy. I think I recall the project cost more than replacement with stainless wire and swaged fitting, but I can’t swear to that. He found it a bit of a problem to source the proper hardware to connect the Dyneema to the toggles in the mast and the turnbuckles at the chain plates. But the hardware was available – probably more so now than 3 or 4 years ago. Since the install he has spent a winter in the islands and made a trip up the East Coast, across the Atlantic to Portugal, into the Med, and back across the Atlantic. He told me he has had to adjust the rig tension periodically, apparently because the Dyneema is slippery and the splices tend to creep under load when subjected to cyclic loading from waves.

As far as those tang (toggles?) fittings that were used on our rigs, it was explained to me that they were a cause of rig failures. The caps were designed to move in tandem with the rod but given that they were a combination of stainless steel and aluminum they quickly seized up and cause the neck of the rod to be nicked and weakened. Hence the newer K200 style of tang which I converted to. Like John Sandford, I had to break all of the original K100 tangs to get them out of the mast. Interestingly, I was thinking Dyform when the rigger started to discuss replacements but he specifically said that it was not Dyform (which he called old technology?) so that?s why I?m at a loss to understand what the type of standing rigging it is. I?ll find out in a week or two when we get together to go over my rig.
