So I have made our first Mobius Locking Brummel splice, with thimble, for our guardrails.
This is in 6mm Hampidjan Dynice Dux from Jimmy Green Marine.
This will be used with a lashing to tension the guardrail. This bit of line will lead to the gate which has “pelican” hook into another thimble. Something like this:
Mostly following this blog post from Rigging Doctor.
Our latch doesn’t include a screw thread to tension the gate so I think we will need to have a separate lashing to tension the gate.
However, we do have a big decision to make about our stanchions. The gates, in particular, are all a bit bent and the diagonal support braces are clearly moving where they are bolted through the deck – obviously a likely source of leaks. Also the stanchion tops, through which the lines pass, have some UV damage.
As we are already replacing the aft most stanchion with the supports for the solar panels using the Tula’s Endless Summer method the question is whether we can afford to replace them all now (well after we fit the chainplate ply backing plates all the way along).
If we do replace the stanchions then I would do so with longer ones for better security (700+mm compared to 600+mm) and with 3 lines instead of 2.
At the bow, we would refit the pulpit onto pads for better waterproofing, but the guardrail lines would slope slightly down to it.
At the stern we have a couple of options. One possibility is that what we build for the aft solar panels replaces the pushpit and so would match the new height. Otherwise a slope similar to the bow will be mostly hidden behind the side solar panels.
No instant decision needed. We can sort the supports for the side solar panels which replace one stanchion per side and see how that goes. That can inform our decision about the other stanchions and the pushpit.
Sustainable Sailing 
I note that there are SS rails atop the stanchions on most modern Amel Yachts.
I am not sure of the height, of the modern Amel ones, but of course taller (within reason) is more desirable from a safety standpoint than shorter, as you have indicated.
So I agree with your upgrade here, and would like to know if the Dyneema in your setup can be tensioned with enough force so as to provide comparitive ‘SS Like’ levels of safety.
One can fearlessly hold oneself by one hand and the stainless railing will not sag. You can place your full weight upon the Stainless rail as you lean out over the gunnel to retrieve something with both hands from the water without having to readjust your stance to compensate for Sag of the lifelines, as is the case on most vessels without SS rails.
In short them Stainless Steel Pipe atop the stanchions is very confidence inspiring. While I believe they are superior to wire, will the Dyneema lines offer SS levels of confidence and safety.

I totally agree that the stainless steel solid top rail is the gold standard. As well as the personal security I like the lack of things for lines to snag on and the reduced chafe for sails.
However, that comes at a high financial cost.
We won’t be able to achieve the same rigidity as solid rails but much better than traditional stanchions and wire (stronger and a thicker line to grip). Plus much easier to maintain/fix.

Well done sir. With unlimited funding we could all theoretically have every feature and amenity aboard our perfect One-Off designed yacht, but very few of us live in that in reality.
You are living the reality, most of us find ourselves in, and are applying your life skills and accumulated knowledge from disparate sources to transform what you have and can afford into what you want it to be.
You have a get-er-done mentality that serves as an inspiration to me. I have criticized you on some things, but you seem to not be put off by that. You take on board legitimate concerns, and just laugh off idiotic critiques as you see fit.
I respect all that you do here, and appreciate you passing on the good and the bad of what works and doesn’t as you go along.
Good on ya.

Thanks.
There are three things that particularly suit us with carbon fibre stanchions.
a) any length you want
b) zero chance of leaks (no bolts, just epoxied pins to drop them onto)
c) cheaper than new stainless steel stanchions and bases
Plus we can have an integrated solution for stanchions, side solar panels and pushpit with aft solar support.
