I’m after a bit of advice. I’m designing a radar arch to mount radar, wind generator, etc. To fit my oceanis 35. My question is what is the best way to run the cables, internally inside the stainless tube? Externally? Advice on how to run thro the deck etc? Thanks in advance
 
To run the cables inside the arch you need a fairly decent diameter tube and each outlet needs a grommet to prevent chafe. I did this on my rib with 45mm tube but it wasn't easy getting the cables through. On my motorboat the radar arch is about 25mm dia so not practical to get the cables through. As for deck exit I used a stainless inverted 'J' from asap supplies. Stainless Steel Cable Elbow Outlet (35mm OD)
 
My radar/solar arch is made from 50mm dia tube with the cables running inside conduit inside the stainless tube making sure the conduit extend outside the arch to the inside of the boat any where the wires come out of the stainless tube to the connections
 
In case this is your first radar installation - the cables for radar have the flexibility of a game fishing rod - I do exaggerate - but narrow tubes, sharp corners and radar cable really don't mix. The tubes you will need for the arch to accept the radar cable will need to be quite hefty - and might be a bit out of place on a Oceanis 35. Your arch will need to be quite high to keep a wind gen out of reach - why not place the radar on the mast, which will give it more height and a less obstructed view forward. I would not bundle the cables but keep them separate - if you need to remove anything you don't want to remove everything!

Ours is a totally different installation, being a cat, but our wind gen (which we would not be without) is on a tall braced pylon on the transom and above boom height and the radar at the first, lower, spreaders.

Most modern radome units seem to offer wifi data connectivity meaning only 12v has to be supplied via cable, that might ease the issue of running a radar cable?

Radar cables have moved on Jonathan. Modern cables consist of a 2 core power cable and a data cable, similar in size and flexibility to a N2K cable.

I would do it as Roger did (#3)
If not for the radar data, but for the power & wind gen. I don't think that they have made wifi wind gens yet ?

I also have a water pipe going p one of the legs to take water to the stern outdoor shower.

The biggest issue I had with my old radar cable was getting the connector through the conduit
