Hello To You All,
Following up on posts regarding dynex dux as a rigging alternative
firstly i must state that my business is fittings and furlers and in particular rope
including dynex and dux, i am happy to update all on progress within this field but apologies to all if this may also seem somewhat commercially driven, hopefully any information i can provide may be of real use generally as it has all been very extensivly tested .
Its great to see an interest in these high strength UHMPE derivatives, (ultra high molecular polyethelene).
Dynex dux is definitly suited to standing rigging, it is very strong, reliable, light and well proven. As opposed to some of the other fibres it is what can be considered "workman like", its properties are well known and it is proven in some very tough environments, probably far tougher than we as yachtsmen will ever subject it to.
The first generation of high strength spectra/dyneema was regarded as being "stretchy", this perception has lingered possibly longer than it should have, with the Dux version we can produce standing rigging that has tested to equal the stretch parameters of 1x 19 stainless dyform but at 85% less weight and usually 30% plus more strength but at a similar price
To achieve this we have developed some techniques ,it takes care and time and a little skill, but we can succesfully terminate this to standard rigging screws, and expect the same kind of adjustment as high quality wire.
My own yacht a 1936 42ft S&S sloop
1936, was fully rigged in dux using this method a year ago, she is moored on a very exposed mooring
, and is sailed a couple of times a week all year round. To date i have added one full turn to the lowers, one half turn to the shrouds and nothing to the backstay in the 12 months since the mast
was re stepped.
We have also rigged a number of widely different other yachts, with no problems.
What is being produced may be beyond what is possible DIY, but does not rule
this out, the rope
is very user friendly.
To date we have had no difficulties with insurers, and our industry experience ( suppling deep sea fishing
, energy exploration) suggest the rope will last at least as long as steel
, we produce a covered finished product and UV is not an issue
Our rigs can, coupled to turnbuckles, appear to a casual glace to be more "steel like" than rope.
As to malicious damage, there are unfortunatly always idiots about, but wire cutters, angle grinders and other implements are freely available at your nearest bulk store, to date i have heard of no sudden upsurge in the cutting of wire rigs because the possibility exists.
Hope this is of some help,
