When I bought my 2007 J92S used, it included some Tacktick wireless instruments with two displays mounted on brackets attached to the mast. There is a Race Master and mn 100-2 analogue wind display, also a mast top remote wireless windspeed and direction sensor and a through hull paddlewheel. I also have a B&G Zeuss chartplotter in the boat, mounted inside the cabin.
Although the Tacktick instruments all still work, I would like to update and replace these wireless instruments with new wired instruments over the off-season. I am leaning toward the Raymarine i70 multifunction display, although I will also consider B&G which seems to be the main competitor. I will run a new wire inside the mast to the masthead to connect a new wired wind sensor in an attempt to get more reliable wind information than a wireless sensor can provide.
I am considering the best way to mount the new display(s).
For various reasons, I might prefer not to mount the new display on the mast. For short course racing, I have a mast bracket mounted Velocitek Pro, which occupies a fair amount of space on the mast already and it might be too crowded for more displays to be mounted there.
The other obvious mounting location would be the aft vertical surface of the cabin top. While this would provide good visibility from the helm, I see the drawbacks as:
1. I will need to choose which side of the companionway to mount the new display, or perhaps mount two displays, one on each side;
2. This will require cutting holes in fibreglass which I am reluctant to do; and
3. There is a plastic liner inside the cabin that covers the aft face of the cabin top which looks like it would be difficult to remove. If I can't remove it, I would need to cut a hole in this interior liner to wire in the new display(s).
I am interested to see how other owners have mounted their instruments, especially pictures of installations. I don't know whether the classic 92's are any different from the 92S in this regard.
Are there any commercially available solutions to this problem? For example, Scanstrut makes a mast bracket that might work (but could interfere with the Velocitek):
