Chafe has always been a concern with Dyneema or any synthetic rigging
As a by product of Hurricane Earl, my synthetic rigging went through a real torture test. There have been continuous questions about how this new technology will hold up to chafe. People have visions of wild eyed Haitians with machetes cutting down there rig. And what about the main sail chafing on rigging during a down wind sleigh ride of a week or more duration? Well I have had my Dyneex rigging for almost a year and have seen no problems as of yet with chafe. I have been VERY satisfied with the rig so far. Of course I have not yet had the pleasure of a week or more downwind sleigh ride.
To the meat of this post, “The torture test”. During Hurricane Earl Angelsea was was pushed into the mangroves that were close aboard my port side. Please refer to the post “How I secure For a hurricane” for a close look at the setup. as the wind backed during passage of the storm winds of about 40-50kts out of the W to SW pushed my port side hard into the mangroves. I didn’t sustain any damage. But while inspecting the boat I noticed this …
The Dyneema held up well.
I estimate that the wind blew from the W to SW for about 3 hours. And as you can see from the above photograph the rigging severely chafed the branches and even broke some off. The result … a little bit of fuzz or none at all on my aft lower or cap shroud that I estimate were taking the brunt of the load.
OK, nuff said about chafe!
