Re: NMEA 2000: what can I actually display?

For more clarification on what iNavX specifically will display, here is the page from the manual showing the 0183 and NMEA 2000 sentences it will recognize and display.

So if your N2K to Wifi bridge can relay these, it will show them.

Iíd tell you to put the money in a new sail, or a sail you donít currently have.

Agreed. This is not about need.

Perhaps more context is helpful. Navajo Lake on the NM/CO border is about half the size of Lanier, and the boat is a 89 Catalina 30. As far as I can tell, all the instruments are original, and the SR Mariner Nav-10 isnít working. The problem may be (in part) wiring issues in the mast.

The only thing I really *need* is depth; the water level varies around the sunken islands around here too. Iíd like the four functions (depth/speed/wind speed & direction) from my current (broken) system, and Iím likely to need to replace at least the display, if not all the transducers. (My research on new transducers versus a analog-digital converter is still inconclusive; advice on that score is also welcome.) Paying the cost of the basic four is worth it to me.

As it happens, Iím also putting in solar, and the Victron controller, which seems like one of the best options out there, claims to have NMEA 2K support. Which is why Iím wondering would I actually be able to display the data, and if so, where? I agree that seeing it at the helm is not the most useful thing, but as Iím not putting in a chart plotter, the only other place would be to get it onto a tablet.

Iím not going to pay $Ks for the privilege, and Iím not going to spend a fortune upgrading all my engine meters, but if there is a solution that is not too expensive, I could have the flexibility to put other future upgrades on the system, if I set it up correctly now.

FloatHub looks cool, but investing in 0183 now does not seem like a good strategy for future proofing. The XB-8000 seems like overkill for me, although I would be tempted if I was sailing off coast.

Thanks for all the helpful input. Online reading varies between breathless brochures (ďNMEA 2K makes everything work together and solves all your problems instantly,Ē Iíve worked with too many computers to believe that) or goes into highly technical details about how to connect this specific devices via this converter, with nothing in between.

Re: NMEA 2000: what can I actually display?

The original transducers from 1985 are still in place, at least until I get a chance to haul out for a bottom job. The original displays were burned by the sun and the cables (with three sections each connected by RCA jacks) were terribly corroded. I ripped the cables out and will do the same to the transducers when I can.

There are several analog to NMEA2K devices out there. Tank Levels, Rudder Angles, etc. So you don't have to spring for a total replacement of existing analog sensors.

To the trolls who say you don't N-E-E-D NMEA2K: Yeah, your right. I don't NEED a windex, telltales, compasses, VHF, charts, engine, electricity or most anything besides a hull, rudder, sail, mast, halyards and sheets. So what's your point?

Can you clarify how iNavX expects to receive "N2K" data? I'm guessing the chetco "seasmart" DIN sentences or the PGN sentences used by the miniplex but when I tried asking your support this I was told it was a programming secret that couldn't be shared.
