Is it acceptable to add new wire spliced to the old wire to thicken the wire and reduce the overall resistance?

I don’t need to google them, I’ve used them in many practical situations for 20+ years.

I used these to join the instrument wires (below deck) from the mast to the cabin electrics.
Worked really well but I am not an electrician and I hope not to have to undo any time soon!

Blimey, didn't look like them.

You should know better by now then.

I appreciate you’re a marine pro. I’m a network hardware engineer. Canbus is pretty low grade, much harder to disrupt with poor connections. You’ve got a serious and unnecessary bee in your bonnet over this.You should know better by now then.

Looks a lot better that the one that I have and ideal for use in confined spaces, so just going to pick one up from Toolstation - about £10 cheaper than Screwfix for the same make if you can believe it, and the shops are opposite each other!

Thanks but sadly I don't have the space to make these up and safely heat shrink the joint but something to think about if starting from scratch

For data connections I like "blue seas" type terminal blocks - I find them a tidier way of managing multiple connections than the Wagos (that I also use but for power connections).
The screw form means they will take a wide variety of styles - bare wire (braided or solid) or crimped ring/spade terminals etc.

If I have space I like to install a short strip of DIN rail & then use bootlace ferrules on the wire going into them. They are easily available, cheap & there's a large range of stuff you can attach to a DIN rail ranging from a simple plain 2 wire terminal, high current breakers for solar & battery connections up to a mini 5 port ethernet router. The terminals are fixed in place & hold the wires going into the terminals steady and can be easily labeled to correspond with numbers on the wires. They look professional because they are - as used widely on larger craft & ships. You can get enclosures for them as well.

I agree I have used DIN rail mounting fo terminals and circuit breakers on my boat as well as industrial panels I used to design and construct
Just a different way of doing the same job as Wago
You can also easy add terminals in the middle of the DIN rail for additional connections .
DIN terminals cab also be connected together for easy multi connections

Another alternative for thin data wires and modest power wires:
https://media.distrelec.com/Web/Downloads/00/28/04380028.pdf
I use these for wires going up the mast (wind transducer, navigation lights). I unstep my mast every year, good not having to leave bare wire ends hanging out of the mast foot over the winter.
Wires are soldered onto the tags (hole type, -550). You can add a piece of heat shrink where the wires go into the stems of the housing for extra protection.

Thanks for all of the advice.
I am just getting to the end of this job and I used Wago connectors as the connection location is very restricted and the connectors are tolerant of my low ability to make a good connection, and are also easy to disconnect where I have made a wrong connection!
However, I am not able to get the Plotter and VHF to talk to each other and show the AIS data collected by the VHF on the plotter screen. The VHF works but does not show any position or data. The Plotter works and does show a correct position.
The tables below show the connection details for both Plotter and VHF and all that I need is for some kind soul (forumite) to tell me which colours to connect?
It did all work before I moved the electrics about and disturbed the connections and if I can be sure of the connections I will trouble shoot elsewhere.

GPS from plotter to VHF
VHF Yellow to plotter brown
VHF Green to plotter green
AIS from VHF to plotter
VHF blue to plotter grey
VHF grey to plotter green
Your table for the plotter is incomplete, it does not show the connections for port 2 etc
Ensure port 2 is set to 38400 baud

Thanks as usual Paul. I have connected the top two correctly but not the bottom two. Long live Wago connectors!
I will give it a go tomorrow and let you know
Thanks again

On a slight thread drift, I have a Standard Horizon VHF, what advantage is there connecting it to my Raymarine Chartplotter, if any?

Depends which makes/models the plotter and VHF are.

Only thing i can think you'll get by connecting the two is position polling. Not sure if anyone actually uses that.
