Shutting down AIS

Many commercial ships from China. Russia and other nations are "going dark" so as to avoid being tracked delivering goods to sanctioned nations.
This means that AIS can no longer be relied upon for early detection of large ships.....and they are no longer seeing you!

Personally, I think this development will have a positive sobering effect on sloppy lookout practices as a result of yachts and ships relying on AIS, instead of their own eyes and Radar.

I just wonder how IMO will handle this government sanctioned shutdown of AIS?

The IMO will say, "Bad, bad, Ruskie!" and that will be about it.

On the high seas the US Navy turns off AIS. Not much different to my mind.

Re: Shutting down AIS

From what I have seen the USCG also runs without AIS even close to shore.

Re: Shutting down AIS

I'm pretty sure the OP and all the respondees here (so far) are prudent enough to run using radar in conjunction with AIS, especially in low visibility situations. They can be/are just symbiotic tools.

I think this issue just points up the need to have a good radar and know what you are looking at.

'and they are no longer seeing you!'

Not so... I can 'go dark' if I choose to do so..... but I can stll receive...

And anyone who thinks AIS is some sort of new age god should trying crossing the Golfo de Guayaquil at night.... a sobering experience....

Re: Shutting down AIS

No biggie to me I view AIS as a useful tool, but far from necessary. And in my cruising grounds, youd be a fool to rely on it anyway.

But I am curious about your references Pelagic. How did you learn about this? Id like to read more.

Thanks. Interesting read indeed. In my quick search I found articles and references to fishing fleets routinely doing the same.

Odd though in the case of Iranian oil shipments. Given then high priority the USA seems to place on strangling the Iranian economy, youd think it would be easy for them to track these shipments via satellite observations. I doubt they need AIS to monitor these tankers.

Re: Shutting down AIS

The main reason I brought this up is that I can see a growing number of justifications for turning AIS off.

...Some will cite piracy or security concerns
....Others political concerns about their identity.
...Many (including me) , just don't like the Big Brother aspects of AIS

Many cruisers I feel over rely on AIS to warn them of other traffic.
That, I believe, is an accident waiting to happen

Re: Shutting down AIS

I agree this is a an unfortunate development but it’s a tiny number of ships in areas that people on this board rarely, if ever, go. If one of these sanction avoiding ships ever approached US or European ports they’d be boarded and fined by any passing CG - who still use radar (and always receive AIS)

The bigger problem is the large number of cruisers in radar-transparent fiberglass boats who use news like this to justify still not transmitting AIS themselves. Few even put up a radar reflector anymore!

This makes me depend solely on a weak radar return instead of both AIS and radar to see them. I also don’t have a CPA since Marpa on fiberglass boats is useless in any sort of sea.

I’m tired of the jerks who can afford a $200,000 boat and $100 a night for a slip but won’t spend $500 to transmit AIS.

I totally agree P. Its one of the reasons Ive never gone to AIS-transmit. I receive only, in part b/c I dont feel the need, nor do I feel comfortable, broadcasting that level of personal information all the time. It all feels at bit like Facebook a bit too creepy and open to abuse.

I know someones going to say then youre not helping others avoid you. This is true, but its not someone elses responsibility to avoid me. Thats my job. If you want to transmit AIS data to all and sundry, fill your boots. I dont need it, and feel no need to do so.

and on cue enters Carl.

Re: Shutting down AIS

It is overblown. Large ships that do not transmit usually watch very carefully (recent navy mishaps excluded). Small boats usually do not venture at night or in bad weather without AIS transmit. So it is self regulating in a way.

Hi Carl
I have AIS but would shut it off in S China Sea, Borneo and Indonesia. Turning it on if Radar indicates a CPA within 2nm

Not being a jerk, just cautious about being tracked.

As others pointed out, fishing fleets, patrol craft have the same concerns and are turning their AIS off.

So apart from being more vigilant, I think this issue will become political in Territorial Waters.

Already its mandatory for Foreign Yachts to transmit AIS in Thailand NOT Locals
(I think maybe the same in Indonesia)

What if that mindset becomes universal.....ALL FOREIGN REGISTERED VESSELS MUST TRANSMIT AIS??
Exemptions for local craft, so that they can be selective about being tracked.

It then becomes a 'Freedom of Navigation' thing to me and same as Mike,..... I don't like people to know where I am

Re: Shutting down AIS

I’m not convinced. My AIS does not have a “dark” mode so it’s on or off.

The only time I would want to not transmit AIS is if there is suspicion of there being “bad guys” around. And the likely good they will be transmitting AIS is about zero.

While it is my responsibility to avoid collisions I know I’m only human and make mistakes, err. So having a second pair of eyes helps, cuts risk by half.

And for sure there are lots of boats without AIS. And because of that it does nothing to reduce your requirement for a good lookout. I am more and more running my radar, even in fair visibility. It too is far from perfect, but better than not having it. It’s a trade off against power usage.

Also it’s in my nature to not worry too much about people knowing my business, I’m a private person for sure, but take fewer than normal precautions to maintain my privacy. That may bite me some day. But it’s just sorta who I’m am, kinda quick to say “eff off.”

Same here, my AIS is either on or off.

SE Asia is an area where personal security is a normal part of life in certain areas.
