My BCC Shanti just went through Hurricane Earl. During the storm Shanti was pushed into the mangroves with about 4-50kts of wind. The Dynex Dux chafed against the mangrove trees for about 3 hours. Tore up the mangrove trees but only raised a little bit of fuzz or nothing at all on the rigging.
I have more details and a photo over at
http://garyfelton.com/shanti/ if your interested.
But I have extreme faith in the synthetic rigging now as far as chafe goes!
Cheers,
Gary
