Need Help/Advice new P42 Owner

[HYPERBARICBOB]

Hi, just bought an older P42 1997 build and need to replace the old radar with new. Anyone have any advice on where the cable runs are? The headliners in the saloon are separate panels, but reluctant to give them a good pull without knowing how they are fixed up? Any advice on how to find the cabling route from lower helm up to the radar arch would be very much welcomed.... Thanks. Called Fairline Yachts and very nice lady tried to help, but still don’t have any good advice where to take down the headliners for this project.

On the Princess 360 of similar vintage, cables run down the starboard upright of the radar arch, ie the helm side ..You will need to remove the panels on inside of radar arch..Cables then enter saloon and run down next to window .Removing the interior saloon settee seating and the wooded panels hidden behind should give you visual access to cables as they run forward.
You may well be lucky and find some pull through cords still in situ hidden away, installed during build.
The Princess actually has some corrugated tubes going from top to bottom preinstalled.
Removing the old very heavy and thick radar cable(in this case Raymarine ) usually leaves plenty of space for thinner more modern cables to pass .
Tie a lanyard to old cable and use that to pull new cabling back up.
The hard bit might be getting cables from repeater displays on flybridge down to interface with main displays in saloon.

I think the OP might be referring to a Fairline Phantom 42, rather than a Princess P42.

I had a 1999 phantom 42 and even back then 3M dual lock existed and Fairline used it to hold up the ceiling panels. So just pull them down using the holes for the lights and they will be easy to refit, and dual lock is easy to buy if you need more.

Thanks one and all, we managed to fit the radar using the existing power cable from the old Furuno as the Raymarine Quantum is a Wi-fi connected unit it only needed power. I had an electronics engineer with me when we fitted it and used the passerelle upright with a ladder cable-tied to the bottom of the passerelle and the aft rail of the Flybridge so we could wedge ourselves between the two under the radar arch with side safety lines rigged between the two. It felt safe enough ?

The only problem was when we opened the old radar cable the engineer had to aggregate the +ve feeds together as they were pretty thin on their own to deliver the voltage. But once enough of these were bundled together, the radar powered up fine. The common -ve lead was a bigger wire and didn’t need anything done to it.

Just have to Sikaflex the panels back on the radar arch now and job done!

Thanks to all that commented!? and very helpful to know the panels are only Velcroed up!
