Wind/speed/Depth Recomemdations

[sailorgreg123]

Hello, I have an approximately 10 yr old Nexus system with Nx2 server on my 36 ft cruising sloop. It has been problematic since I bought the boat with it already installed (intermittent readings, no data displayed, etc). Nexus was bought by Garmin and is no longer supported. I want to rip it out and install all new electronics that will display the following:

Apparent wind speed / angle
True wind speed / angle - must interface with SOG
Boat speed
SOG
Depth
Temp
Interface with my existing and functioning Raymarine Autopilot (steer by wind angle)
(X-30 smart controller) ST60? Control display

Any recommendations on best system - easiest to install the current thru hulls are 43mm twist lock.

Thanks much in advance for any help with this frustrating problem.

is your current system NMEA 2K bus or 0183?

The nexus is a proprietary network and the autopilot is seatalk I believe.

OK, so you are basically proposing keeping the ST60 and upgrading everything else, and hopefully reusing the thru-hull.

I replaced all the "electronics" in 1974 boat and could not be happier with the result. I installed an NEMA 2K bus and was impressed with the level of compatibility between the brands.

I used a Maretron DST800 for depth/speed/temp, but the Raymarine version I found out later would have been much cheaper (<$200 from Hodges Marine). You will need poke around to see if the thru-hull is compatible with the nexus version.

For wind speed and direction I used the the LCJ Capteurs CV7. The thing about CV7 if if you have 4 wires coming down the mast from the old system, you can just splice in if don't want to run a new wire since it's good old RS-232. That keeps you from having to run the N2K bus up the mast. A quick review below.

Then you just need to get a small Raymarine for display of the wind info. RM makes a dedicated wind display or just get a RM small chartplotter, which would be simple to connect to the seatalk AP.

Even though I have 3 brands of instruments talking on N2K bus, they just work.
