I selectively and carefully incorporated dyneema and it’s heat treated cousin Dynex Dux into the rebuilt Far Reach. I used Dux for the forestay and later modified it with a quick release pendant. The link to how we made the forestay releaseable can be found here. https://farreachvoyages.wordpress.com/2017/10/23/a-new-forestay-release-device/
We also use dyneema for our lifelines and various shackles with and without toggles. The dyneema has performed very well. We continue to find ways to use dyneema in a manner that suits our philosophy of reliability, simplicity, and self sufficiency.
