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 used a 5/16” doubled soft shackle to attach the large low friction ring to the tack fitting on the gammon iron as part of our releasable forestay system.
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.
