Class B AIS

They are also excellent radio operators (the radio training in the UK in general is vastly better).

ASIDE: I can't comment on radiotelephone procedure and operating skill in the U.K by their Coast Guard, but I will say that lately the level of skill and radiotelephone procedure I hear from USA Coast Guard operators is not very high. We have done a lot of boating in Canadian water, and for decades enjoyed listening to their live operators reading weather and other marine bulletins, almost always with a Scottish accent. Sadly they're all gone now, too, replace by computer generated voices or recorded messages.

Am I the OP? If so I absolutely want to xmit

Sorry, your thread has been lost in a mud slide of techno talk, acronyms and initialisations.....

Just go buy the one you can afford with a usb plug.

Oooops, USB is an initialisation

Hey no problem, until they got way over my head, I was learning something

I want Wifi, I assume there are plotters that are Wifi and can display AIS targets?
I would also assume that soon if not already that RADAR etc will be wifi, hopefully meaning all you would have to run to it , is power? Be nice to only have one power supply cable going up the mast and everything be wifi, even the anchor light wouldn't it?

I have the vesper marine vision mate. Great purchase! I use it as a stand alone and when I m cruising any distance I mount my iPad above my wheel and use INAVX with all of the AIS data sent to it by wifi. I agree that it has been one of my better purchases. We do a lot of night sailing and it is a nice added feature. I have had a few problems understanding something and the guys at vesper respond extremely fast to my questions.

The vesper vision mate is both transmit and receive. I use an antenna specific for it and can see out around 24 miles

That one is I believe what I will end up with, question becomes buy it now, or wait until we actually leave full time?
I was about to order it, but Mon morning I found out the wife's car needed two tires $300, and the washing machine finally died $500
Maybe next month

Unless you frequent crowded shipping lanes I would wait until you are about 6 months from leaving. Technology is moving fast and bugs are still being worked out. Prices are still going down too.

I think you are a little off the track. While the AIS and the plotter may have WIFI, they use this exclusively to communicate with an iPad or similar device. An AIS will NOT transmit the data to the plotter via WIFI. This is exclusively done via NMEA0183 or NMEA2000 or derivaties of these standard AND this travels via cable. I don't see RADAR coming any time soon with wireless data transfer to the plotter.

I may be wrong, but that is what I know.

I believe Furuno recently introduced a radar unit that sends via bluetooth (could be Wifi) from the radar unit to the screen (I asked, but they said I could not rig this unit to my MFD12)

Yep , saw one of the Furuno radars at the Auckland boat show.... wifi(?) to your Ipad... not for me....
Scanner still needs hard wired 12V
My AIS... an AMEC Camino 101.. could be bought with the optional bluetooth.... dunno how that worked or what it worked with.. http://www.milltechmarine.com/custom...101_manual.pdf

I see your point, and I may wait, just I'm waiting for a lot of things and darnit, I want some toys Plus honestly from a financial perspective it's sometime easier to spread things out a little

Thank you, that is exactly the info I need

I hope soon that we will see more wireless devices meant to communicate with each other, be nice to not to have to run all of that wire, except of course power.
Wouldn't a portable plotter that would display speed, depth, position, RADAR and AIS be nice to have? If this data was wireless then you could have that

I'd have thought an "error correction" capability would more likely be associated with the GPS receiver accuracy. IOW, before AIS broadcast. Perhaps either DGPS when near enough, or WAAS-corrected...

Since DGPS probably doesn't make as much sense if way offshore... I expected our unit would tell me ours is WAAS-corrected...

But the manual simply says (on the topic of correction):

4.10 DGPS data correcting By AIS information

And I'm not exactly sure what that means

You have formed the wrong impression. The reference to "error correction" was in regard to forward correction of error in digital data transmission over a one-way broadcast radio link, not to uncertainty or inaccuracy in a position solution of a global navigation satellite system.

Ah. Fair enough.
