    Sometimes it is unbelievable how slow NMEA 2000 development is…
    I heard that Navico is going to release a replacement for the NAIS-300, I guess that once that is released they will fix this silly Class B omission in the MFDs.

  2. Don Joyce says:

    Ben,
    Aren’t the Raymarine AIS 650 and Em-Trak B100 essentially the same and therefore score the same on your Shame Sheet?

    Seems to take a while
    http://www.yachtbits.com/navico/_nais_300_class_b_ais_transceiver.php
    ……THIS PRODUCT IS NOW DISCONTINUED – REPLACEMENT VERSION DUE EARLY MARCH – PLEASE EMAIL US AND WE WILL KEEP YOU UP TO DATE WITH THE REPLACEMENT……
    So I bought a digital yacht transponder.
    CTRX+actisense was giving vessels in the wrong direction on the screen.

  4. Kees says:

    Hendrik,
    Guess they are waiting with the release until the chartplotters can actually use the new product aka the new software ain’t ready?
    Are you using NMEA 2000 with the Digital Yacht transponder or have you given in as to the wrong direction? I’ve got wrong direction on some AIS vessels as well, with my NAIS-300 -> N2K -> Lowrance HDS system. Disappointing, and I was hoping every time that new HDS software would fix this. 2 years on and no luck.

  5. Ben Ellison Ben Ellison says:

    I left the Em-Trak B100 running this evening and you can see it on ShipFinder. But more interesting is the fact that big yacht called Blind Date apparently burned and sank off Sandy Hook, NY, late this afternoon. You can see some of the emergency response boats still on the scene and if you look at the track of the yacht Erica XII you’ll see how it ran a search grid. I think everyone survived:

  6. Matt Marsh says:

    Raymarine and Navico are sufficiently large, well-supported outfits that I would expect more up-to-date firmware from them.
    I would have a really hard time faulting smaller shops on this issue, though. Consider a team of four or five engineers and coders, swamped in bug reports and feature requests, with a growing list of products that were supposed to ship yesterday. They can easily be forgiven for leaving something like AIS-B static data parsing on the heap while more pressing issues are addressed.

  7. Doug McEwen says:

    I am looking to purchase a radar/MFD, AIS system and DSC radio, and rather like the Em-Trak B100 for its low cost, so have been following this with interest. Given the issues in this post, the limited NMEA 0183 inputs to MFDs and a strong desire to avoid purchasing a NMEA multiplexer, it would suggest that a standalone AIS display is the best route. Assuming I stick with standards-based solutions, the cheapest option (since I need a DSC radio) would be a GX2000 from Standard Horizen, but the AIS display on this unit has very limited resolution. The next cheapest option would be a display from Vesper, and the most expensive (although most flexible) is a Raymarine i70. I suppose a dedicated Lowrance HDS-7m could be standards-based by using a dedicated NMEA 0183 input, although it goes against my grain to purchase one knowing they don’t currently adhere to the NMEA 2000 standard. Can you comment on your preferences for these last options? Given that Vesper does not publish a manual online, and that Raymarine publishes precious little info on the AIS application within the i70, it is difficult to compare these two options.

  8. Richard C says:

    Ben,
    You mentioned having a sort of “voyage recorder” now. I really like the idea of creating a record of the last 30 minutes of what’s going on around me. Coastal Explorer ECS, the commercial version of Rose Points software, does have a real voyage recorder. There is a YouTube training video that covers this feature. Wish Rose Point would add voyage recorder to the 2011 recreational version or sell it as an “add-on” feature.
    I agree, Coastal Explorer handles AIS really well.

  9. Dominique says:

    A very instructive test, as always, thanks !
    It would have been interesting to add one more test based on iPad with iNavX + the SeaSmart WiFi gateway. Any chance to add this one to your list ?

  10. Ben Ellison Ben Ellison says:

    Weird that the yacht fire off NY turned out to be a false alarm compelling enough to scramble 7 helicopters and all manner of boats and ambulances: http://goo.gl/WvCWK
    Richard, “voyage recorder” is probably an overstatement on my part but the Em-Trak B100 does save your own vessel track (if the GPS strings were enabled using ProAIS) and AIS target data in a standard NMEA 0183 file that looks like this:
    “$GPRMC,192121.00,A,4412.50580,N,06903.72587,W,0.045,,090612,,,D*6A
    $GPGGA,192121.00,4412.50580,N,06903.72587,W,2,12,0.78,7.2,M,-30.3,M,,0000*69
    $GPGLL,4412.50580,N,06903.72587,W,192121.00,A,D*7E
    $GPGBS,192121.00,1.9,1.4,2.0,,,,*46
    !AIVDM,1,1,,B,15N;[email protected],0*54”
    I could not get it to work right using the undocumented and unsupported log file playback in CE 2011. But it plays back in GPSGate fine, and using that I can watch my track and all AIS targets play back in CE. Could be particularly useful if someone strange happened like the Blind Date thing.
    I wonder, BTW, if the authorities checked Marine Traffic (or a more complete private or gov. AIS tracking service). On MT I see one 150 foot Blind Date (MMSI: 378344000) underway in the Med right now, while another one (MMSI: 319009300) was last seen in Miami 83 days ago.

  11. Ben Ellison Ben Ellison says:

    Doug, I’m not following your reasoning well. I think that the Standard Horizon AIS Matrix products are great for certain uses — like smaller boats, backup AIS display, DSC calls to targets — but it would seem a shame to install a full transponder and only have a GX2000 for display.
    I think I should emphasize that AIS over N2K works really well except for this business of Class B static data, which is what makes that ongoing glitch so irritating. Especially as it could be easily fixed, I think. Maybe Kees can confirm that the way NMEA 2000 works, his Lowrance HDS could be deciphering the standard 129809 and 12810 PGNs while also still supporting Navico’s proprietary equivalent?
    I haven’t heard back from Navico but I think Raymarine is surprised about the problem I’m seeing (which I double checked yesterday using a different N2K network). And they may have the same problem with their own AIS650 as Norse found that it claims to use the standard 129809 and 10 PGNs (and also, as Don notes, is very likely manufactured by the same company that makes the Em-Trak).
    I think this glitch will get straightened out, but, Doug, have you considered Garmin? I’ve already seen that my test 7212 works fine with the Em-Trak B100 — and probably all the other new N2K transponders coming to market — and I’ll bet that it can use this standard target data to place DSC calls on its VHF radios, all via N2K.

  12. Bill Lentz says:

    I like my early NAVICO 300 unit with my Garmin network. My best MFD is a Garmin 6212 but it does not provide me with the Class B vessel name. Other then no vessel naming of AIS class B vessels all the other data shows up on all the MFDs those on the NMEA2000 network and Garmin network and can be reviewed.
    I have the latest software in the Garmin 740s, 4210 and 6212. My NAVICO’s AIS300L has firmware revision is 1100 100101.
    Is there a Navico update for the AIS class B transponder I am unaware of?

  13. Ben Ellison Ben Ellison says:

    Bill, Apparently Navico never updated the NAIS 300 (now discontinued according to a comment above) or the Simrad AI50. Nor did they update their MFD software so that it can also decode the standard Class B static data messages. So while Navico transponders and MFDs work fine together over SimNet/N2K, neither is completely compatible with other brand MFDs or transponders.

  14. norse says:

    If your AIS indicated that there was a danger, one of the options that is a valuable feature is the ability to call the other vessel on the VHF. For that it would be helpful to know the name of that vessel. That should be there now.
    Another feature is to call using MMSI. For that it would be helpful to be able to avoid keying in all those digits. That should be coming “soon”.
    Eventually, all AIS units will follow the standards and the features which distinguish them will be things like VHF antenna splitters and other things not specified by the standards. (The standards for Class A and Class B should be pretty stable by now, although other new features can be expected and it takes time for them to filter down through all the layers of organizations involved.)
    The real action will be in the MFD or dedicated displays, in how they present the information to the user. There is a lot there that could be improved. Personally, I like the idea of layers, each of which can be quickly and easily flipped on and off: chart, radar, ais.
    BTW, it seems someone forgot to tell Simrad that the NAIS-300 is discontinued; it’s still on their web site with no mention of that or its replacement.

  15. Kees says:

    @Ben,
    Yes, receiving multiple PGNs should not be hard to program. There are various strategies of course: – listen to both, – ignore the standard one if you see any proprietary ones, – ignore the proprietary one if you see any standard ones.
    @Bill,
    Unfortunately the NAIS300 cannot be field upgraded apparently. It is a slightly different beast from other Simnet devices. It actually contains a normal NMEA0183 SRT AIS circuit board as well as a Navico built NMEA2000 interface. I had a Simrad distributor round about a year ago and he was able to update my IS20 displays etc., but he did not have any updates for some others such as my WR20 and NAIS300. This did not matter as they were running the ‘latest’ version. Having customers flash new updates is something that is both good (we get updates) and bad (companies feel they can ship not-yet-ready products).
    What Navico doesn’t have yet is some user capability of updating non-MFD/Radar devices as the updates are only given out to dealers that have a programming device.

  16. Hendrik says:

    Kees,
    Could be, it is silent at Navico a this time. Expecting new NSE/NSO software and Gofree any minute, day, week, month.
    Direction is okay now with my NMEA2000 Digital Yacht transponder.
    Don’t know what you mean by …or have you given in as to the wrong direction?…
    I also complained about the moored AIS vessels that still sound the dangerous vessel alarm mor than a year agoo, but still no solution. Very annoying in our harbour

  17. Peter Daum says:

    Thanks to everybody for raising this. As I am about to upgrade my equipment, reading this I get annoyed. I exactly have the combination of an AI50 together with i70 displays and a Maretron compass. The latter two talk well to another. However, it seems that the representation of AIS data on the NMEA2000 bus will be incomplete. To make things worse, it seems that the AI50 does not accept HDG data through its NMEA0183 interface, ut only through 2000. As I also face the challenge to channel all this into and out of my Transas NaviSailor plotter, it seems I will eventually end up with two parallel networks. Does anybody know if there is a possibility to
    a) make the AI50 accept HDG data via 183,or
    b) enable it to digest HDG via 2000 without sending AIS data on the bus or
    c) get the proprietary class B static info converted to the standard PGN by an external unit?
    Best

  20. Bill Lentz says:

    Peter I also use a Maretron NMEA2000 heading sensor along with numerous Garmin NMEA2000 sensors and weather receivers. My NAVICO AIS unit works extremely well my main complaint is I can’t find a local NAVICO dealer that can upgrade or program the NAIS300. I have a spare but both have my MMSI entered in them. It is used on my NMEA2000 network using their adapter cable that came with both units. I had a self alarming AIS problem which was fixed with a Garmin update on the MFD’s. The MFD’s thought the NAVICO was a threat but Garmin now gives you the ability to enter your MMSI this eliminated my own vessel from being a dangerous target. It took a bit longer to get the 740s updated. However I would still like to see the vessel name from other class B AIS vessels.

  21. Keith says:

    I have a Digital Yacht AIT2000 which works faultlessly with my Garmin 5008. From the Garmin MFD I can instigate a call to any chosen AIS vessel via my Garmin VHF200. It all integrates nicely over n2k for me.

  22. s/v Haven says:

    I hope that Garmin’s involvement with Americas cup will lead to a new set of plotters that blow Simrad nss and Ray out of the water.
    I just did a leg… arrived a few hours ago
    .. from Jupiter FL to Beaufort NC.
    . 3 day sail. The plotter had to be rebooted about once a day or it went crazy. The Raymarine knotmeter looses its calibration for no apparent reason. The Raymarine autopilot went to standby and the boat rounded up all by itself. This is inexcusable.
    At Miami show a nice guy at Simrad said that since they are owned by private equity they don’t fix bugs. … people buy new products and features not bug fixes.
    Is it true that Garmin stuff has fewer bugs?? I’m a custo
    Typing this on a phone so sorry for the typos

  23. Ben Ellison Ben Ellison says:

    I’m tickled that reading Panbo is one of the first things you did ashore, but maybe you need a nap? I’m sure that Simrad and all the other marine electronics companies — regardless of ownership structure — know that their reputation for supporting their products is a critical sales component.

  24. sumps.myopenid.com says:

    Great article Ben and your findings pretty much match what we are hearing from our customers. Fortunately connecting a Class B transponder via NMEA 0183 is a good work around for Navico and Raymarine customers that cannot get static Class B data via NMEA 2000 but it would be great if new firmware updates become available very soon.
    I think it would be good to add the AIS SART support to your Shame List table as this will be the next area of confusion and incompatibility – one of the reasons we have developed our AIS Life Guard product.

  25. Ben Ellison Ben Ellison says:

    Good news re: Raymarine c- and e-Series and the standard Class B static data PGNs. While Ray acknowledges that they forgot to include them, apparently they are being tested in a beta software update that is scheduled for release in July.
    I have not heard back from Navico about this, but will bug them again.
    PS. Thanks, Paul S. Judging from the other thread, it is looking like a spreadsheet about AIS SARTs and MoB devices and how they’re plotted may be in order. But so far the nuances don’t seem related to which NMEA protocol they’re received on.

  26. Paul says:

    Ben, a few messages above you include a NMEA message string, the last two sentences being:
    !AIVDM,1,1,,B,15N;[email protected] !AIVDO,1,1,,,B5NI4OP00>hugK6DgH86OwbUoP06,0*54
    Note that the !AIVDM message is ill-formed, with no parity at the end. Is this just a typo?

  27. Ben Ellison Ben Ellison says:

    No one typed that, Paul; the NMEA text was cut and pasted from a log file created by the Em-Trak B100. I’ll try to record one that’s reasonable file size and includes AIS SART testing, and make it available for download.

  28. Ben Ellison Ben Ellison says:

    Got preliminary good news from Navico, with promised confirmation tomorrow. When published, the Shame Sheet my be short lived, at least for products currently in production.

  29. Hendrik says:

    Let’s hope so.
    Any news about Gofree by the way?

    Ben, I am all ears hopefully a upgrade for the NAIS300? I bought a spare when they came out.

  31. Ben Ellison Ben Ellison says:

    It was a vague message, Bill, and I think I should have said “MFDs currently in production”; I’m getting the impression that transponders are not easy to update.

  32. Bill Lentz says:

    I would send the (2) NAVICO NAIS300 out if I could find someone who could update them in the southern New Jersey area. One needs the old MMSI removed and a new MMSI put in it for my 22′ center console. If there is a factory update for the missing static Class B AIS I would have both upgraded. My installed AIS300 has my MMSI from the Mainship.

  33. Kees says:

    Bill, you can reset the NAIS-300 to factory default after which you can program in a new MMSI using ProAIS (the software that came with the device.)
    See http://yachtelectronics.blogspot.nl/2011/02/srt-proprietary-ais-commands.html last paragraph.

  34. Ben Ellison Ben Ellison says:

    Navico AIS N2K news confirmed: An “RTM2” update for the Simrad NSS Series expected to “release within a couple of weeks” has “support for PGNS 129809 and 129810 to decode standard AIS Class B Static Data” (and lots of other enhancements).
    Plus, since most Navico displays are based on a common operating system code (NOS), “the AIS feature will make it into other products as SW updates develop across each brand’s product line.”

  35. Peter Daum says:

    Thanks for keeping us posted. So, no good news on the AI50?

  36. Kees says:

    Peter, the AI-50 and NAIS-300 use a technology that does not support user field updates.
    if you have an AI-50 or NAIS-300, and you want Class B AIS information on a non-Navico MFD, your best bet is probably NMEA-0183.
    Another option would be to feed this through an Actisense NGW-1 and let that convert the NMEA-0183 to NMEA-2000. I think Hendrik here did this for a while before he upgraded to a new AIS transceiver?

  37. Peter Daum says:

    Thanks for the clarification. I think the 183 route would be feasible provided that the AI%0 is willing to accept HDG information from the compass by 183 as well. Unfortunately, it seems that the only way to get the compass heading into the AI50 is 2000. A split setup (183 for getting AIS out, 2000 for getting HDG in) is in my opinion not desirable.

  38. Hendrik says:

    Kees,
    Correct and static data was visible then.
    NGW-1 is still at my desk, willing to be sold.

  42. Ben Ellison Ben Ellison says:

    Sorry to report that I am having a (small) issue with the Em-Trak B100. I can not get it to output target data over USB and NMEA 2000 simultaneously. It will do either output fine by itself but not both at the same time. Em-Trak is investigating.

  43. Hendrik says:

    Actisense is sold, sent and delivered to it’s new user.
    Thanks to Panbo!

  44. norse says:

    Good news — I just noticed this on a Simrad website:
    NAIS-400 AIS
    “latest generation, fully integrated, Class-B AIS transponder”
    http://www.simrad-yachting.com/en-US/Products/AIS/NAIS-400-ClassB-AIS-en-us.aspx
    USB type A plug [but the manual says mini-B], NMEA 2000 *standard* connector, plus NMEA 0183 at both speeds.
    Configuration is with proAIS2, which I believe indicates that the AIS engine is by SRT.
    This quote is in the Troubleshooting section of the manual, in response to “My MMSI is being received by other vessels, but my vessel name is not shown on their chartplotter or PC”:

    Some older AIS devices and chartplotters do not process the specific class B AIS message, which provides the vessel name (message 24). This is not a fault of your AIS transceiver. Software upgrades are available for many older chartplotters which will correct this issue. The other vessel should update its AIS unit and/or chartplotting software to receive AIS message 24.

    An antenna splitter specific to this unit is also available.

  45. Ben Ellison Ben Ellison says:

    Good catch, Norse. I agree that it’s likely built by SRT but sort of odd that Navico removed the SD card logger. That’s a feature they pioneered in the Simrad AI50!

  46. Ben Ellison Ben Ellison says:

    Incidentally, I finally made the whole “Panbo AIS over NMEA 2000 Info Sheet” into a downloadable PDF, which you’ll find in the PS above. And, yes, I even took “shame” out of the title, because a lot of headway has been made, or will be made with software updates “coming soon.” But there are still issues for owners of older N2K transponders and MFDs and I hope the sheet clarifies them. It now also has some good reference material thanks to the efforts of Norse.

  47. Hendrik says:

    Oops,
    New Digital Yacht AIT2000
    NSE12 and NSO
    But no names on AIS B Vessels

  48. Ben Ellison Ben Ellison says:

    Don’t despair, Hendrik, but patience may be required. Like the info sheet says Navico plans a software update that will decode the standard Class B static data. In fact, the NSS8 on Gizmo is now decoding Class B fine, because it’s running an early copy of a software release that’s due out quite soon (lots of other improvements and fixes too). The new code will eventually get to NSE, NSO, and I think the Lowrance MFD line too. You will see Class B vessel names, dimensions, type, and call sign with that DY transponder, eventually.

  49. Hendrik says:

    I don’t Ben 🙂
    Maybe all will come at once.
    Navionics chart update, so radar and AIS overlay’s will fit the chart.
    NSE and NSO updates.
    Gofree.
    AIS alarm off for ships that don’t move.
    Current vectors like we were used to on the CX44
    Possibility to draw lines on the charts like on the CX44
    etc.

  50. Kees says:

    I’ll second your request Hendrik, especially for the current vectors!
    I don’t understand your first point though, “AIS overlays will fit the chart”?

  51. Hendrik says:

    Aalscholver symbol, Radarimages and AIS Vessels are 30 metres off position on my Navionics maps. Ehh, I mean the maps are off.
    Map correction is on its way for almost a year now.
    Navionic promised me it would be solved this summer

  52. Knut says:

    I installed a Furuno NN3D MFD8 when this modell was brand new.
    This year i decided to upgrade with
    -AIS Class B Transceiver em-trak B100
    -New instruments Raymarine i70
    Heading data come from a NMEA 0183 heding sensor connected to the NN3D and is shared on N2K network
    Connected the the NN3D and the em-trak to the StNg network.
    First I discovered that the NN3D does not take AIS data on NMEA 2000 (my fault should not have assumed that). Connected those two using NMEA 0183 (also).
    Some observations;
    The NN3D does not know what a AIS base station is…
    When the NN3D unit is turned off, the i70 claims that the AIS is off when it is not (the power to the N2K network is not supplied by the NN3D).
    Guessing that the message on the i70 should be no heading data?
    The i70 is much better at displaying data about the AIS targets and use different icons for base stations and other targets.
    Does anyone know how AIS-Sart’s will be diplayed on i70 and NN3D?

  53. Ben Ellison Ben Ellison says:

    Hi Knut,
    The i70 acknowledges AIS SARTs but needs work, example here: http://goo.gl/V2iCb
    I think it may also need a fix regarding AIS display and Heading. At least once my test i70 didn’t display N2K AIS data from a Ray AIS 650 (sibling to EM-Trak B100) when the N2K compass was detached. Will check out further, as there’s no reason why, I don’t think.
    I don’t have a NN3D MFD for testing anymore but hope to try the TZTouch, which does receive AIS over NMEA 2000.

  54. Knut says:

    Thank you.
    There is probably hope for a new SW from Raymarine since this is new devices..
    Only problem is that there are no Raymarine plotters in my network – so updating will require some work.
    I’m not that optimistic about new SW for the NN3D since it has been replaced by TZTouch.
    Support from Furuno Norway is non existent for the NN3D. The don’t bother to answer support requests..

  55. Jeff says:

    Ben, I am about to install my em-trak b100 and a new NavNet3D 8-inch MFD. Have you heard any feedback as to whether that configuration properly handles the N2k data issues? Thanks.

  56. Ben Ellison Ben Ellison says:

    Jeff, NavNet3D never had any issues with AIS over NMEA 2000 because it doesn’t support it all! But you should be able to wire the B100 NMEA 0183 output to the MFD8 just fine, and if you get another NN3D MFD it will get the AIS over Furuno’s Ethernet network.
    Furuno has changed its AIS ways with the new TZtouch series. It accepts AIS over N2K. The only boat I’ve seen it installed on has problems with AIS over N2K or from Furuno’s own FA50 via Ethernet, but apparently it’s the only TZT install that’s had such problems.

  57. Mikkel says:

    Hi Ben,
    If I understand you correct, the new Simrad NSS software will make the MFD talk NMEA2K AIS with native AIS NMEA2K equipment?
    Do you have any information regarding when we can expect a similar software update for the NSE units?
    BR
    Mikkel

  58. Ben Ellison Ben Ellison says:

    Correct, Mikkel. As promised the new NSS software decodes the standard NMEA 2000 static data messages fine now. I’ve seen it in action. And, yes, I’ve heard that the code will be added to future NSE and other Navico MFD updates.

  59. Ben Ellison Ben Ellison says:

    Good news: Raymarine just introduced software version 4.27 for c-Series and e-Series, and it includes full support for the NMEA 2000 Static Data message. There’s also all sorts of enhancements in what’s called Lighthouse V4, info and video here:

    The Shame List is dwindling fast!

    Ben; just to confirm the nss update which is their 2.0 software version DOES address the missing AIS static data? I read the description of the what is contained in the update and see no reference to anything AIS-ish. It could just be my ignorance showing.
    As always, thank you for your help.

    Kees reviews the Navico NAIS-400 here:
    http://yachtelectronics.blogspot.ca/2012/11/navico-nais-400-reviewed.html
    It supports both the new and old Class B PGNs.
    There is a software upgrade for the NAIS-400 announced here:
    http://www.simrad-yachting.com/en-US/News/2012/New-NAIS-400-software-now-available/

    The new software allows the SimNet or NMEA 2000® network to use the NAIS-400 as the source for position data, thanks to the enabling of new NMEA 2000® sentence transmission.

    The equivalent Lowrance page says:

    The new software allows the NAIS-400 to transmit the following NMEA2000 sentences.
    PGN129026 COG and SOG, Rapid Update.
    PGN129025 Position, Rapid Update.

  62. Mikkel Mandrup says:

    I know this might be a bit off topic, but can anybody explain why we don’t see any ais class a transponders with nmea2000 interfaces.
    As rules are changing now in EU all recreational boats above 18m needs to have class a transponders from 2013 and 15m from 2014, I would expect the market for class a receivers to be a lot bigger soon?

  63. Kees says:

    Mikkel,
    Do you have a reference to a source for that change in EU regulations?

  64. Kees says:

    I did a bit of searching, and EU recreational boaters don’t need to worry.
    There is an EU regulation 2009/17/eg that enforced AIS class A on fishing vessels larger than 15m. See http://eur-lex.europa.eu/LexUriServ/LexUriServ.do?uri=OJ:L:2009:131:0101:0113:EN:PDF
    The only change coming in the coming few years is that these will become mandatory for existing fishing vessels, not just new ones.
    Here is a Google translation of the relevant change for Dutch law, which I presume will be similar in most or all EU countries (as they have to implement regulation 2009/17/eg in some form):
    The Automatic Identification System (AIS) is mandatory on all vessels longer than 15 meters. On new vessels longer than 15 meters and existing vessels of 45 meters or more, the AIS is mandatory.
    For who? Dutch and foreign fishing vessels: operating in the internal waters or territorial waters of the Netherlands; landing their catch in a port in the Netherlands.
    When?
    The amendment shall enter into force in stages. For fishing vessels: 24 meters or more, but less than 45 meters: 31 May 2012; 18 meters or more, but less than 24 meters: 31 May 2013; more than 15 meters but less than 18 meters: May 31, 2014.

  65. Mikkel Mandrup says:

    Ok, I stand corrected 🙂
    Was information I got from a dealer, and I believe that what you has posted was what he got mixed up with some Dutch inland ais rules for recreational boats above 20m
    I haven’t got any links to the specific rules like you posted above, but many Dutch shops have the following information posted: http://www.shiptron.nl/php/ais_transponder.php
    But thanks for the clarification.
    Would still like to know if there is any good reason for class a transponders don’t have nmea2000 interface 🙂

  66. Ben Ellison Ben Ellison says:

    Thanks for the good detective work, Kees!
    I wonder if that over 20m inland Dutch rule isn’t also limited to commercial vessels?
    Mikkel, there are Class A transponders with NMEA 2000.
    I wrote about the ComNav Voyager X3 here: http://goo.gl/0doFx
    And today I realized that McMurdo has just introduced the SmartFind M5 that’s similar but with a color screen and built-in charts:
    http://www.mcmurdomarine.com/en/products/ais-electronics

  67. Mikkel Mandrup says:

    I’m impressed by the speed and qualified responses here – Thanks 🙂
    About the Comnav transponder, I haven’t been able to find information about the nmea 2000 interface ever has been activated.
    In the leaflet from Comnav they still write this will be suported by a firmware update ultimo 2010…
    But the McMurdo seems very interesting and priced decently.
    Thanks again for the great answers from both of you 🙂

  68. Kees says:

    Ben, you are probably right.
    First of all, those inland regulations will mandate EU Inland AIS which is NOT Class A, although I’m not sure what the technical differences are.
    Some countries like Austria have already mandated Inland AIS for commercial traffic. Also, entering Antwerp harbor in Belgium requires AIS for commercial traffic.
    The Dutch authorities have so far been reluctant to make Inland AIS mandatory, largely because of widespread privacy concerns amongst the 7000+ barge shippers. The barges have largely adopted AIS anyway because they were almost free because they were heavily subsidized.
    I’ve heard that the Dutch authorities will probably vote in favor of mandatory AIS on the Rhine in the next CCR (Central Committee for the navigation of the Rhine) meeting though. What this means in terms of who, what and when remains to be seen.

  69. Ben Ellison Ben Ellison says:

    Glad to help, Mikkel. You asked an interesting question, plus I think you made Kees a bit nervous about EU requirements ;-0
    I don’t know what the story is with the ComNav Class A but I’m pretty sure that it’s actually manufactured by SRT, which lists NMEA 2000 as an available interface:
    http://www.srt-marine.com/products/oem/products/class-a
    I don’t know for sure but I suspect that SRT may also make the new McMurdo Class A, but haven’t yet listed it on their OEM pages.

    Class B static data and AIS AtoNs now supported by new Simrad NSE 3.2 and NSO 1.3 software

  71. norse says:

    This is good news. The NSE and NSO update pages say:

    *April 2013 update* Added PGN129041 – AIS AtoNs (Aids to Navigation) support. Will now display AtoNs when interfaced to a compatible AIS receiver that transmits the PGN.
    *April 2013 update* Added PGN129809 & PGN129810 – AIS Class-B Static Data support

    The NSS update 2.5 page says:

    *April 2013 update* – Support for AtoNs (Aids to Navigation)

    I think the Class B PGNs were added in the NSS 2.0 update, but then so was the AtoNs PGN.

  72. Hendrik says:

    NSS new 2,5 version is on line as well from 2013-04-04

  73. Ben Ellison Ben Ellison says:

    Thanks for keeping us ‘updated’ Henning! Looks like the April add-ons are:
    *April 2013 update* – Support for using Navionics Silver Chart Cards on devices with no internal chart
    *April 2013 update* – Support for AtoNs (Aids to Navigation)

  74. norse says:

    Simrad is good now, but Lowrance does not yet have any MFDs, old or new, that do Class B AIS with the 129809 and 129810 PGNs, and no PGN for AtoNs either.

  75. Anonymous says:

    I have an HDS Gen1, and I’ve given up on AIS compatibility. I’d drop in a receiver in a heartbeat if the various manufacturers would all support the proper PGNs.

  76. Henning says:

    It was Hendrik not me updating us on the new NSO and NSS software and thank you for that. It’s downloading right now.
    I use a NMEA0183-based AIS. Can I assume that NSS will display AtoNs from VDM and VDO sentences as well, even if not related to this update?

  77. Hendrik says:

    Ben is not responding to me anymore since I asked him what price I won in the “C-map on Navico products contest) 😉

  78. Andreas says:

    So now I’m totally confused..I really want to add an AIS transceiver using NMEA 2000 to my boat. I understand the Lowrance HDS display have issues with the standard Class B PGN’s. So I contacted Lowrance via their website to ask them specifically about support for class B PGN’s.. Here is the reply.. According to them, they are supported. According to everybody else, they are not.. Clear as mud… Here is their response, and my original question below.
    —————————————————
    Yes, the HDS-8 will support these PNG’S.
    Thank you for choosing Navico products!

    question: I would like to add an AIS transceiver to my boat. I need to know if my Gen 1 HDS 8 will support NMEA 2000 PGN’s 129809 & 129810. I am currently running the 4.1 software. If the two PGN’s are not supported, do you have any plans on adding support?

  79. norse says:

    Andreas, your question was clear and we know that 4.1 doesn’t support these PGNs, so the only interpretation of their response that makes sense is that when they say “Yes, the HDS-8 will support these PNG’S”, they are using the word ‘will’ in future tense. Hopefully that means ‘soon’ and not ‘real soon now’ (for those not familiar with the software world, that is a joke). HDS software update 4.1 is dated 02/09/12 (Feb 2012) and there are no more recent updates listed.

  80. Hendrik says:

    If your Mfd can handle it, make sure your ais can too.
    For instance SRT needs firmware 1.7

    Furuno released a new SW version for NN3D the other day.
    From the release notes.
    “NN3D V2.11 Software (latest)

    *New: Compatibility with AIS-SART. Instead of a generic AIS triangle icon, SART icon is
    displayed. AIS –SART symbols are now displayed on NN3D MFD8/12 and MFDBB
    …”
    Have anyone installed this SW and verified that it is working with AIS Sart beacons?
    During my test I found that it ignored the AIS sart completely.
    It did show up on my Raymarine i70 display and on other (non Furuno) MFD’s around me.
    I use an Em-trak b100
    The i70 get data on NMEA 2000
    The MFD8 get the same data on NMEA 0183

  82. Hendrik says:

    Has the emtrak the latest proAIS software?

  83. Knut says:

    Yes the em-trak is running v1.7
