The latest version of our own DIY mast tangs to attach dyneema shrouds to the mast. Significant changes from version 2 including the materials and way of making them. Thanks for all the help in getting this far! Now made from single pieces of Acetal-C with grooves cut on the router. Shaped to fit the curve of the mast.
We are going to test these by putting up our mizzen mast for an exposed Welsh winter.
Our goals are
- reduced potential points of failure compared to traditional tangs, pins and thimbles.
- a tang that is very Dyneema friendly without sharp bends or edges. We have a diameter 7x the shroud diameter!
- simple for DIY, so replacement tangs can be made anywhere with a router, drill and sander providing you carry some spare Acetal-C rod.
This design will be a huge cost saver if you are renewing the rigging on an older boat when you might otherwise need to replace several of the stainless steel parts of the original tangs even if you are fitting dyneema shrouds. This is experimental prototyping of a design that began on our blog a couple of years ago. We have had loads of help improving the design which is very much appreciated.

We are changing all the standing rigging on our 1977 Rival 38 to Dyneema synthetic rigging. That includes all shrouds, stays and even the chainplates for both masts of our ketch rig.
This is the 9th episode in our Dyneema series that will cover all the design choices, the practicalities of a completely DIY re-rig and then how it works out when we go sailing.
Our goal is a rig that is:
- stronger
- lighter
- cheaper
- allows us to sail faster
- lasts longer
- can be DIY maintained even replaced, anywhere in the world
We are refitting a 1977 Rival 38 for a Sustainable Sailing retirement in a few years. Three years ago, when we bought Vida she was in a very tired and damp condition with all original equipment and fittings (much of it not working). We have removed all the gas, diesel and paraffin equipment, and are installing all-electric (motor, cooking etc). Lots more detail on our blog at sustainablesailing.net/
