Excellent news: Shine Micro has figured out a way to ship its Class B AIS securely locked into silent mode (receive only) so that it’s legal here in the U.S.A., even though the FCC commissioners continue to drag their feet on Class B approval. The idea is that you can install a high quality, true dual-channel AIS receiver now and as soon as the FCC relents you’ll be able to unlock the unit’s transmitter via an online activation scheme. Shine Micro is even sharing some of the “risk” of this proposition, not collecting $200 of the cost until said activation, as explained here.
Sometimes you-know-who works in mysterious ways. On Saturday afternoon I watched a long-time friend, Tom Amory, set sail for Finland with his daughter and her friend, but without the Simrad AI50 Class B AIS transponder he’d tried so hard to obtain. I was excited for him, but also yet further ripped at the FCC. Tom ordered the unit from a Canadian distributor who agreed to ship it to the U.S. for use in international waters, but insisted on putting its true identity on the customs form. It got turned back at the border! Then Tom employed an alternative importation technique, which didn’t work in time. Note to the FCC commissioners: What the hell are you doing, making an upright citizen smuggle in a U.S. Coast Guard approved safety tool that he can legally use about 3,988 miles of his 4,000 mile voyage?!?!
Milltech Marine is carrying a new AIS display of particular interest to power-sensitive offshore sailors. The Vesper Marine AIS WatchMate has a 5–inch “daylight readable” monochrome screen, but purportedly only draws 1.2 watts average, 2.5 max. The $499 unit is not a receiver and does not do graphic target plotting, but I read through the preliminary manual and was impressed by how thoroughly the designers—who are offshore sailors—thought out the details of collision avoidance. For instance, WatchMate not only has range and CPA/TCPA alarms with sophisticated filtering, but also supports four “profiles” so you can easily switch setups in different conditions like “offshore” or “coastal”. It strikes me that WatchMate would also work well with a Class B transponder, though of course you’d still need a PC connection to set it up and, sigh, you can’t buy one in the U.S. yet. Note, too, that those NMEA 0183 ports shown below are actually wires in a single cable, and should be fairly easy to install in a waterproof way, plus there are several other possible install configurations. Hopefully Milltech or Vesper will make the manual available soon.
I haven’t done one of these AIS miscellaneous entries since last June, but even then was wondering why the FCC hadn’t yet approved Class B! Now it seems like the U.S. marine safety community has gone into a state of depression about it. I’m no longer getting e-mails guessing when the FCC commissioners might finally act, and don’t know of any recent efforts to make that happen. Color me guilty too, though I did turn an April PMY Q&A into a mini editorial on the subject (it’s below the electronics maintenance story some of you helped me with). But I’ve been encouraged to try another avenue, which I’ll describe below, after a few this’n’thats
I guess this sort of thing was inevitable, thanks to FCC recalcitrance, but still it’s a sad sale for all but a few. Apparently PortVision, an interesting U.S.-based commercial marine information service, has concluded that the FCC is not about to allow Class B AIS anytime soon, and is liquidating its inventory of SRT transponders (update: sorry, all gone). You may recall that SRT Marine Technology—which once did business as Software Radio—developed the core technology that’s in every Class B transponder currently approved by the U.S. Coast Guard and other certification authorities.
OK, admittedly I’m in a foul too-much-work mood, and maybe that’s why I find NASA’s new AIS Engine 2 so totally exasperating. Sure, they added “Power” and “Data” LED status lights, a big improvement over the original, but that’s just catching up with the Smart Radio SR161 that has deservedly stolen much of NASA’s business at the low end of AIS receivers. And note how Milltech carefully explains that the SR161 only receives one of the two AIS channels at a time, scanning back and forth, while the NASA specs are, um, less clear about that limitation.
Last Wednesday night, the 97' clam dredge Captain Joe sank suddenly 30 miles off Point Pleasant, New Jersey in 10' seas. Air and sea temperatures were in the low 40’s and the wind NW near 30 knots (according to a nearby C-Man buoy). You can hear some, maybe all, of the bone-chilling May Day call here. It’s unclear whether the crew gave any position info before jumping into their liferaft, yet within hours rescue swimmers helped all four into the baskets of two USCG helicopters.
A month or so ago reader Derek Love (thanks!) wrote in about an interesting combination VHF transceiver and AIS receiver previewed by Icom UK at the London Boat Show. It got a little coverage plus there’s an Icom UK web page about it, though that page seems oddly inaccessible from the main site. I’ve tried to find out more and what I hear is that the prototype is a small board that can be added to Icom M505 and M603 radios, but preferably during manufacturing, not as after-market mod, because of the waterproofing.
Whereas I got the week started on what’s largely a trade subject, let me add an unsolicited suggestion to everyone who makes plotters, multifunction displays, or any other marine electronics with a dedicated screen and some sort of accessible memory. If possible, please add a screenshot feature! My intent is obviously selfish; dumping .jpg or .bmp files to a CF or SD card is so much easier than photographing displays, and the results so much better for web and magazine readers.
Man, the AIS traffic was heavy out there in the Gulf of Maine! Actually I was using the very neat AIS Simulation software created by Mats Kågstrøm of Firma Mats Kagstrom. Specifically I was testing how many AIS targets a Raymarine E-Series can handle simultaneously, as I got a report from a user who says his resets randomly when more than 100 ships are within range. Well, I did see the test E slow down, even stutter a bit, but I was able to feed it the maximum number of targets the simulator can produce without causing a reset. That’s some 510 Class A targets (!), plus a Class B (which the E “saw”), and even SAR aircraft and ATON AIS target messages (which the E doesn’t seem to understand). You can see Kagstrom’s software in action below, and bigger here.
AIS Simulator is very thorough and is going to be terriffic for testing navigation hardware and software. But I’ll write more about later, because I don’t want to head back to my judging duties until I pass on the good news about Class B AIS. To quote one of the many cautiously optimistic emails I got on this subject yesterday (thanks, all!): “We heard from the FCC that it looks like the AIS Second Report and Order will be on the Commission's Agenda for the Feb. 26 meeting. There is a *chance* that the item will be voted on before that time.” Maybe our letters and emails helped, but I also know that the GMDSS Task Force, the USCG, and the RTCM have all been making their feelings known to the FCC. The latter even spoke with an FCC legal aid, very effectively too, as judged from this PDF documenting the meeting (also a good summary of the situation). Cross your fingers!
