Anyone had experience of getting wires from the Doghouse down to the Nav Station. I have managed in the past when there has been a panel blanking the coachroof winches ie halfway house but I am now faced with getting from the 'hole' in the breakwater down to the Nav station. Thus far I have tried an Electricians nylon rod & various stainless steel wires without success - it is probably the transition from horizontal to vertical thats preventing success. Is it just a case of patience & repeated attempts?
All suggestions welcomed!

I found that job a lot easier by removing the roof panel from the pilot berth. 

Good Luck

This probably doesn't help but there is a lot to be said for Tacktick wireless instruments.

Thanks George
Don't think they do a GPS Repeater!
The head lining panel above the 'coffin' berth has been removed but its the transition from horizontal to vertical thats the problem. I am too chicken to use one of the existing Seatalk cables to pull a 'string' through.

If you get the NMEA interface box (that is probably not it's correct name) then Tacktick displays will repeat GPS data.  That said I have a Nasa repeater, but only because it came with the boat and works surprisingly well.
 
Sorry, still not much help to you though.

We were faced with this challenge when fitting new instruments. The first couple of cables went through fairly easily, although the last one took a few hours of fiddling! A few things I found to help:
1) Can you use one of the existing cables as a mouse? If you have a few feet of spare length, you can tape a piece of string/cord to the existng cable and this may allow you to pull this through as a mouse, you can then attach the new cable(s) to the mouse and pull them through
2) Is there anything compressing the deckhead to the coachroof? I found that the bolts on the jammers on the coachroof were slightly compressing the two together. By loosening them off temporarily it freed up enough space to get the cable through.
3) Can you remove any of the old cables (or use these as a mouse)? this may just allow enough space for the new cables.
4) if you can't go in one direction try the other. Most instrument cables can be cut and reconnected without a problem if the wires are single cores. I would be hesitant to do this with Coaxial cables.
5) If none of this works it may be possible to use the old cables if they are still there for this short part of the cable run with the new cables.


Good luck! You will need it with this job.

Thanks for your input. This is the 4th GPS Repeater I have fitted! Thats 4 different CO32s. The problem is that the other instruments are Raymarine ST60s & the Seatalk cables are not really easy to disconnect.
Where the winch has been replaced there are 'bungs' and I guess with patience I might be able to work to & from the bung holes - just needs patience and warm fingers!

Hi Colin,

It was ST60's and Seatalk with GPS repeaters I installed. It can be straightforward to tap into. If you want to give me some details of the instruments you have and are fitting I may be able to help you out and might even be able to save you running additional cables. If you feel a phone call may be easier our phone number is under Liz Wisdish on the Committee page of the website. 

Best Regards,

Mark

Thanks Mark
Patience paid off in the end this morning - I was able to run a thin stainless wire through in stages via plugs in the headlining where the clutches and winches had been re-fitted. I now have 2 mouse strings to pull the wiring through. Just the final wiring plus NMEA interface to do once I have fixed the very smart new black acrylic fascia to the garage this afternoon.

Really pleased you succeeded - I had B & G and was unable to shift the old cables at all. While Raymarine don't recommend it, after talking to the local installer, there are just enough cores in the B & G to run a full set of ST60 instruments and compass, so while most of the cabling is Raymarine, the last few feet are B & G! Works fine.
