In getting electronics for our upcoming boat, I'm debating AIS. Not to get into any political discussion about surveillance etc., but I'm curious who has and uses AIS here? If getting electronics now, would you get it?

Thanks!
 
Are we talking receiving or transmitting?

I receive only. Mostly for being able to see the big ships coming from a distance. With AIS and the shipping lanes I can plan safe crossings well in advance. Also helpful when crossing the ferry lanes.

I do not find it very useful with pleasure boats. Recreational boats are unpredictable and the AIS only tells me where they were not were they are. I much prefer radar for dealing with recreational boats.
 
AIS is probably the best and biggest advancement in navigation tools in the 21st century. I would definitely add it, and only consider a transceiver. Receive-only is just freeloading off those of us who transmit.

Agree completely. Transmitting is just as if not more important than receiving. I want the big commercial ships to see me and be able to call me by name on the VHF. Let them tell me what to do do to stay out of their way.
 
You didnt ask abput those that dont have it and arent running out to get it.

It can depend a lot on how and where you boat.

Might give your specific requirements and look to those responses that match up.
 
Thanks everyone!

Good point. It's for a new Helmsman 38. Usage area will be coastal New England, Long Island Sound north to the Maine coast.
 
I would have found it nice to have on our trip up the Hudson. Not really needed here on Lake Champlain. In my opinion I'd like it for communicating with the commercial vessels and them to us.
 
It’s invaluable for running around New England in the fog. Now the target on your radar has a name and info available and the radar target can see your name and info. The Navy Warship would have known that he was talking to a light house if he had AIS. :)

FWIW I'm getting send and receive.

I'll never know if it prevents some yahoo from running into me. But I'll go for the protection. One the least expensive upgrade choices in my package.

I have a receiver and I find its utility very limited as few pleasure boats in NE have transmitters. Price would have to drop dramatically for me to purchase transmitter.
 
I have it and like it. I transmit and receive. It was great being able to other boats by name when meeting them on the ICW. When crossing to the Bahamas, I had a freighter call us by name to make sure I was going to cross behind him and not in front of him.

I do wish that people that have it would input their correct info into it though. I came across several boats that changed the boat name but never updated the AIS. Maybe they don't know they have it after buying a boat.
 
Send and receive. Boat buck for boat buck, best value in onboard comnav equipment in my view.
 
I have had AIS (receive only) on my previous boat and sure miss it on my new to me Mainship 350. I loved being able to see the large ships since I cross the shippin lanes, Port of Los Angles regularly on my way out fishing. It is very busy and it is not unusual to have heavy fog roll in on no notice.
I got AIS back then on a Standard Horizon Matrix radio with AIS and GPS. It wired up to my Garmin 942xs no problem. I loved that the AIS targets showed up on my chart plotter and radar,
I will be repeating this same set up very soon. Highly recommend.
 
Have it and use it. Agree with those who say it's the best thing to come along in a long time.
 
We use our AIS transceiver 24/7 and never turn it off. It shows up on our radar screen and is used with the radar.

I think Twisted tree's comments are spot on. If you ever run in open water it should be mandatory. :)

Yeah this is really annoying. Cruising South from Hilton Head to Bahamas, I find 50% of boats , especially sailboats for some reason, have not entered any name so hailing is a PITA.
 
Ive had receive only on previous sailboats and now tx/rx on our current trawler. I like to be able to call other vessels by name. Also getting closest point of approach and time to that point are helpful in deciding course speed changes. Easier in many ways than radar which we also have.

Ours is a simrad modular vhf/ais unit with upper and lower microphone and speaker handsets. Can provide hailer/listener but we don't use those. Integrated with nmea2000 we get the ais presentation on both simrad chartplotters.

AIS is nice. The biggest problem is that is AIS xmit is not required on all boats (say for all boats that have radios). Currently large boats and commercial ships are required to have it, but even then sometimes it gets turned off. IMO, it's not the big boats you have to look out for.

If AIS was required, then lots more installations would be necessary and hopefully the price would come down.

It's sort of like seat belts, air bags, or backup cameras in cars. They have demonstrated a safety improvement and now are required equipment.
 
I’ve had a tx/rcv on my last 2 boats. Find it very helpful on overnight nearshore runs past ports like Charleston and Savannah. Also fishing boats which may or may not maintain a proper watch are easily avoided if they have their unit on. I vote you get one.

Pulling out of my slip in Commencement Bay (Tacoma WA) the other day before dawn I needed to get into a channel but in front of me was a large barge moving towards the same channel with two partially hidden tugs hip tied on its far side. It was also raining so visibility was crap. I could also see the lights of one free tug presumably awaiting pilot duties for an incoming container ship and another which appeared to be leaving the area with a barge in tow.

Using AIS I was able to identify the name of the one tug I wanted to speak with (lead tug hip tied to the barge) and discuss an order of passage into the channel. In the absence of AIS I would have had at least two possible responders to my hail (two tugs on the barge) as well as potentially the other towing tug.

Case proven for me.

I don't find the cost of an AIS transceiver too high for what it gives me. A quick search turns up many affordable options. Screenshot_20230118-174508_Firefox.jpg
 
For those who boat in areas that have reliable cell coverage, go to your APP Store and get one of the many AIS Apps. Marine Traffic is there and loads quickly, but is not real time. The one I use combines good navigation charts with AIS, and is Real Time, all for a low annual fee, though unless you leave it on, you may want one that loads more quickly.
When I leave cell service, unless I have my phone as a hot spot, I get charts where there is GPS, but no AIS information.

As it is on my phone, I have it with me wherever I go. A few days ago I used it to navigate on a shoreside walk in Honolulu, far from my boat.

Which APP is real time? I've compared Marine Traffic and Vessel Finder to onboard AIS and found the lag unacceptable.
 
We were crossing Lake Ontario in a torrential deluge. The radar was in white out. We couldn’t pick up any returns. But on AIS we could see 2 freighters on th plotter. On obviously would pass ahead of us. The second one was on a collision course with us. Just as I was preparing to call the second freighter he called us by name since we had a transceiver. We were stand on and he was give way. He told us that he was preparing to make a turn to pass astern of us. If we didn’t have the transceiver we would not have even know he was there and he wouldn’t have been able to call us by name. It made it simple to make passing arrangements.
 
Hi Nick14, I have recv and xmit ais on my Mainship here on the Tennessee River. Most of the big commercial traffic is large river barge tows. sure is nice when one calls me to co-ordinate a pass in a narrow channel. Also running up and down the ICW occasionally puts me in the Gulf with both military and commercial traffic. River traffic can see me on AIS when line of site radar is nearly useless extremely helpful in the winter when fog is prevelent on the river. I can see a tow coming on AIS long before I can pick him up on radar and take action to give him room to maneuver or tuck into a cove or duck behind an Island to hide from his wake.



Frankly I would not leave the dock with out it.
 
It's a pretty easy call, I think.
As Comodave points out, it will give you a solid target for AIS equipped vessels in circumstances where radar is ineffective or less effective including, for example, around the corner in narrow channels and passes.
It is far simpler to operate than radar, and less expensive to fit.
And it is just as good to be seen yourself... so get a transceiver. Make it easy for commercial vessels to understand what you are up to in close quarters. I am willing to let the NSA know that I'm going down current in Dodd Narrows if the tug and boom on the other side can also see me.
 
I can’t imagine doing the cruising we did without AIS. Yes we were class B, and we had correct information in the system. We did experience less service when away from US and Canadian waters. We treated AIS as an enhanced radar feature, but best of all was when we contacted large commercial ships and asked what we could do to avoid close contact. I dont care who has the right of way, we could change course much easier than a 1000 ft freighter and make our trip so much safer and smoother. If you have ever had a 800 ft tanker overtake you in a river system like the Columbia river (US waters, not the country) you know what it like.
Dont skimp on this feature, you wont regret it.
 
Boatbeacon



Used to be called Boatbeacon. When I renewed a couple of years ago it had combined with the Nav App and is now called SeaNavNP $37.99.
I watch ships gping past my house and have this App and Marine Traffic. Marine Traffic can be a few seconds but is usually a few minutes late. Boatbeacon is almost always RealTime.
 
What surprised me in our encounter with the 900’+ freighter was that he readily charged course to go around me. He was the give way vessel but I expected some grief about it, but no he did the correct thing right away. It was refreshing.
