I’m anti AIS. BUT......

When Rule 10 applies. But in open water they for sure are looking at their AIS targets. You really want to appear on their screens not just with radar.

Listen? You can't always hear a fast ship coming down a busy TSS in time to be out of danger. And what if they are so busy that there is always a ship audible? Or see it, especially in fog. AIS worth its weight in gold in these situations. Doesn't replace radar, but particularly in heavy traffic it so much speeds up plotting that you can deal with many more targets at once, than you can without it.

Good stuff, Dockhead.

The one think I should add is that I don’t need a robust chart plotter.

I don’t need to leave the salon sailing this new boat. The indoor helm and nav station are one thing. One area. It’s L-shaped. Wheel in front of you, nav computer to the right. So it’s all indoors and climate controlled.

To go without a plotter/MFD he can use OpenCPN, which has a good radar plug-in. This works with a number of radars, but I can tesitfy that it works flawlessly with the Navico 3G and 4G radars. A used 3G radome will be dirt cheap and works pretty well.


OpenCPN can also use data from a black box AIS.


But a 7" Vulcan or Zeus MFD, especially one which is a generation or two obsolete, will cost peanuts, and is vastly better than using a fragile home computer or IPad.



AIS Type B has been replaced with a new type some call B+. B+ is better, but B is good enough. These are being sold cheap as they are now obsolete. Used will be even cheaper, but make sure you can still put your MMSI into it -- some of them can only be reprogrammed once before going back to the factory.


If you are going to be single handing and not always keeping a watch (which I don't recommend), then you REALLY want to be broadcasting AIS so that people see you. You really should not use a receive-only AIS.


You will also want to be sure that your radar reflector is up to snuff.

Are you not familiar with required sound signals in fog?

What are you trying to convince me of here when I’m the one asking for advice on what AIS transmission device to get???

I'm not trying to convince you of anything, and I hope have given useful advice on AIS.


Not all vessels sound proper fog signals, or better say very many vessels don't sound proper fog signals, so fog is a pretty dangerous situation. You will be happy, or least you will be much safer, when you have your new AIS and radar set up

Vesper 8000xb ais / iPad and Furuno dsrw4 or 1620.

Probably the cheapest way to do what you want without diy electronics.

If you're not planning on transmitting AIS all the time, you might consider a radar transponder instead. It will paint an enhanced target on the radar screens of the other vessels, like a racon buoy, and alert you that there's a vessel in radar range.

Commercial Captains and crews have enough to do trying to get from point A to B while using AIS, good communication and prudent watches.
So YOU find some aspects of AIS irritating? Really? Interesting.
You choose to take “cat naps” ? OK ...When you get run over, be a gentleman and please go down with your ship.
The problem is that the manatees are not always on a nice steel commercial vessel which can run you over with some paint or prop damage. They have an aluminum yacht and while it will probably sink a lot of plastic toys, it might get dented...Now they have to fish your carcass out of the drink, use cold beer and frozen pizza on you till the medical examiner begins dissection.
Waste cold beer on someone who wants to sail without AIS.

If you want to sail with no AIS some itty bitty plastic toy...have at it.
Just don’t ask anyone to risk their life saving you. BUT..unfortunately...
We are Legally obligated to do so. A fact which does not change our opinion of you. And you can fill in the blanks.
The manatee crew are trained professional mariners who use every available technology and proper watchkeeping to avoid injuring others.
They respect not just the letter of the law, but the work of all those who continue to improve safety at sea. AIS is just such an improvement. Your choice to not transmit speaks volumes about you.
Merry Christmas and a safe New Year.

Most AIS units i have seen have a silent mode that can either be activated via software, or by connecting a toggle switch to it. I've done it on rare occasion with my vesper, and a close friend does it on his raymarine. So this part of your question is easy.

The most inexpensive Radar units use wifi and will work with an ipad an no chart plotter needed. Navionics can also connect to a wifi AIS to display AIS targets. Getting radar and AIS on the same screen on an ipad might be tough.

OpenCPN might be the best option there, as it supports both radar and AIS. You will need to confirm what radars work with it before buying.

If a chartplotter is an acceptable cost, the Axiom 7 is relatively inexpensive (as cheap as a new ipad) and supports radar and AIS. The biggest downside is the ridiculous cost of charts for it.

Buy a second hand chart plotter , a second hand radar and a new SOTDMA class B transmit AIS. Do not bother with receive AIS.

[Chotu]

Your post makes me not want to get it AT ALL.

I used to think you were a decent guy. That was trash.

Plus I ASKED WHAT HARDWARE I COULD USE TO HAVE A DECENT TRANSPONDER AND RADAR SETUP SO I COULD HAVE A PROXIMITY ALARM.


Are you encased in ice up there? It would seem the cranium of the manatee froze over solid. Very dense.

Or maybe you don’t know what a transponder is? Either way, the manatee cranium seems dense as can be from all the ice this year.

This post is so objectionable and such a personal attack, I should report it. Shame on you.

Really?? I’m surprised to hear this, actually.

So you would say the radar targets are sufficient as a proximity alarm?

I was trying to get a little more reliability so if something that didn’t show up on radar as a target ventured into close proximity, I’d get them on AIS assuming they had it.

Not worth the extra hassle?

Thank you! I will look these up!

[Chotu]

Thanks to all. Some good advice on what transponder and radar to get keeping costs under control.


To the jerks of the thread... why????

[Time2Go]

If you decide to only receive
and as you have stated
your VHF has AIS, Do this
But a YAKER from Yakerbit
connect positive , negative, one wire from the
VHF ( on my SH 2400 it’s the blue)
and presto you can see AIS on most
WiFi enabled tablets ( mine an Ipad running
both TZIboat and INavX)
Soon I will test the “AIS RADAR “ App
For what it’s worth as soon as I feel
like dropping another BoatBuck
it will be for a Vesper TX/RX with it own
dedicated display
Don’t really understand the reluctance to
broadcast, the one exception would be in
pirate infested areas.
You going there?
I know of boats that have been boarded by authorities
because of the flag up the pole , look at me , behavior
of toggling their AIS on and off
Cheers
Neil
