  • Commented on Furuno TZtouch2 and FI-70, back in the game!
    Furuno TZTouch2 is coming. Some online outlets say they can ship TZTL15F or TZTL12F MFDs next week, and some say the week after (and some don't mention actual availability at all ;-)....

    Let me add that if you have some professional connection to the AIS industry or related regulatory bodies, please at least state your affiliation. That and other Panbo commenting policies here: http://www.panbo.com/archives/2011/04/panbo_surveys_comments_paris.html And no offense meant to Ross Norsworthy --...
  • Posted SRT acquires Class B AIS patent, consequences uncertain to Panbo: The Marine Electronics Hub

    SRT_Acquisition_of_Patent_release_clips_aPanbo.jpgFor me, this story began with a March 5th email titled "AIS patent wars - a tax on safety?" It referenced the SRT stock market announcement partially shown above and went on to say:

    The whole point of using CSTDMA instead of SoTDMA in the original design of Class B was to avoid any problems with patents to ensure the successful uptake of the system by manufacturers. I see this as a tax on safety and a desperate attempt by SRT to force manufacturers to use their solutions rather than those from competitors and so create a pseudo-monopoly in the Class B world, which cannot be good for competition or the end user. To say I am furious would be putting it mildly...

  • Commented on SOTDMA Class B AIS, the "new" middle way?
    Ask and ye shall receive, every once in a while. From SRT, not me: "The first thing to say is that it is impossible to take a single practical experiment as a defacto statement of fact. The reason for that...
  • Commented on SOTDMA Class B AIS, the "new" middle way?
    The USCG AIS Class comparison document seems to flawed or unclear on several points. Here's clarification courtesy of SRT: * At higher speeds there are two Class B/SO position reporting rates, Normal and Increased Reporting Interval. The latter is used...
  • Commented on AIShub, how you too can put AIS targets online

  • Commented on SOTDMA Class B AIS, the "new" middle way?
    AIS doesn't always help to prevent collisions, but sometimes it provides good documentation: http://maritime-executive.com/article/container-ship-and-lpg-tanker-collide Thanks to Chris at ACR for the link....
  • Commented on AIShub, how you too can put AIS targets online
    Thanks, Leo; great stuff! But I'd appreciate more information on how you set up the Netcom-111 server to upload the AIS target data to Marine Traffic using either TCP or UDP. Keeping a PC running is my main impediment to...
  • Commented on SOTDMA Class B AIS, the "new" middle way?
    Yes, Dan, I'm sure that position reporting gets more frequent as vessel speed increases, just like Class A. So I agree that the Class Comparison table would be clearer if it read "Either every 5, 15 or 30 s based...
  • Commented on SOTDMA Class B AIS, the "new" middle way?
    Thanks, Leo, but it looks from the USCG table that IEC 62287-2 requires a SOTDMA Class B to have an MKD. So there won't be a black box version, though the display doesn't have to be hi res color. On...
  • Commented on SOTDMA Class B AIS, the "new" middle way?
    Thanks, Don, but I've been hearing from the experts that power has little to do with AIS range. Last winter I heard that from Jeff Robbins at Vesper and also from SRT's Simon Tucker, who wrote: "The range of AIS...
  • Commented on SOTDMA Class B AIS, the "new" middle way?
    Yes, the math gets easy at 30 knots. Then a boat is moving one nautical mile every 2 minutes, or 1/4 mile every 30 seconds. So when you plot such a boat as a Class B AIS target there is...
  • Commented on Nobeltec TimeZero, "most advanced marine navigation App for iPad on the market"?
    Karl, charting apps aren't really free if you have to purchase the charts in the app. i-boating looks interesting but folks who want completely free access to all the NOAA vector charts i-boating charges $15 for should check out Navionics...
  • Posted SOTDMA Class B AIS, the "new" middle way? to Panbo: The Marine Electronics Hub

    SRT_5W_SOTDMA_AIS_Class_B_on_way_aPanbo.jpg

    It may be a while before we see the first 5 Watt SOTDMA Class B AIS transceiver actually available for sale, but it certainly is interesting to see a prototype trumpeted in SRT's Summer 2015 Pulse Newsletter (available here). Given SRT's main role as an original equipment manufacturer (OEM) we may first see this "new" AIS technology -- perhaps with even more features -- branded as Simrad, Raymarine, True Heading, Digital Yacht, Comar etc. (and/or marketed under SRT's own Em-Trak label). Or maybe Furuno, AMEC, Vesper or another of the independent AIS manufacturers will be first out with SOTDMA Class B? I don't know. More important is SOTDMA Class B as a coming middle ground between the Class A AIS used on large vessels (which also works on the SOTDMA protocol) and the CSTDMA Class B technology that we're used to...

  • Commented on Coastal Explorer PC charting revisited, with love to WPx
    Sparky, what are the specific problems with Navico GPX files? I know I imported a complex route made in CE into the Simrad NSS evo2 system fine, including verbose waypoint names. On the other hand, a large NSS GPX file...
  • Commented on Coastal Marine WiFi, a winner!
    The RedPort Halo WiFi Extender is another new and interesting boat WiFi solution: http://www.redportglobal.com/marine-satellite-internet-firewall-routers/halo-wifi-extender-system/ While likely similar in WiFi performance to CMW, Rogue Wave etc. what's special here is the use of a RedPort Optimizer router for the onboard LAN....
  • Commented on Coastal Marine WiFi, a winner!
    Island Time has a great reputation for what they do, but it's not really the same thing. To the best of my knowledge they have not customized the radio firmware, let alone developed apps optimized for picking hotspots. In my...
  • Commented on Garmin GNX 120/130, 7- and 10-inch NMEA 2000 instrument displays
    Hi Kevin, Another good source on how to design a NMEA2000/SeaTalkNG is this: http://www.maretron.com/products/pdf/Network%20Installation%20Guide.pdf Without a diagram I can't really tell what you're up to, but here are some thoughts: *Yes you can add the iTC-5 to the end of...
  • Commented on Coastal Explorer PC charting revisited, with love to WPx
    I'm not sure, Dan. In Voyage Plan you can ask CE to "Assign Closest Current Station to all Legs" and also to "Calculate the best departure time" within a user selected date/hour range. The route detail screen will then show...
  • Posted Coastal Marine WiFi, a winner! to Panbo: The Marine Electronics Hub

    Coastal_Marine_WiFi_hardware_cPanbo.jpgSince early May I've used the Coastal Marine WiFi kit with all sorts of onboard WiFi devices and all sorts of Internet hotspots, and I'm very impressed with its smart design and easy, reliable performance. Yes, the overall system architecture is quite similar to several other good boat WiFi "booster" solutions like the various Wave Rogue and Bitstorm Xtreme kits, but there's a lot of nuance to making these systems easy to install and operate. And whereas many boaters are still understandably confused about the WiFi booster/router combo that's so unlike what they use at home or office, I'm going to dig deep into how the CMW goes together and what it can do...

  • Commented on Coastal Explorer PC charting revisited, with love to WPx
    Sorry for the wrong presumptions, Ron, but note that the WPx feature could fit on any size screen. It just replaces Destination info. Garmin HomePort for Windows (or Mac) is excellent and now free: https://buy.garmin.com/en-US/US/maps/trip-planning/homeport-/prod64242.html...
  • Commented on Garmin AIS600 TX problem
    Maybe a dumb question, Jerry, but have you checked out the status LED's on the AIS600? The one marked TX flashes if the unit is transmitting....
  • Commented on Is online boat donation a good idea?
    Here's another example in my area of a real and worthy marine-related non-profit that accepts boat donations and then auctions them off: http://bangordailynews.com/community/maine-maritime-academy-boat-auction-sealed-bid-sale/?ref=regionmidcoast...
  • Commented on Coastal Explorer PC charting revisited, with love to WPx
    Cy, thank you for much for the clarification. The situation is kind of what I suspected but it's good to hear from Rose Point that route uploading over NMEA 2000 could be done using existing PGNs. And I'm hopeful that...
  • Commented on Coastal Explorer PC charting revisited, with love to WPx
    I'm beginning to think that I did not explain WPx well. I just added a PS with a photo Ron took of his Garmin 3210 showing its Active Route page. It's useful for sure, letting you see accumulated distances and...
  • Commented on Coastal Explorer PC charting revisited, with love to WPx
    Thanks, Ron. I found the manual and explanation of Active Route Details, but no screenshot. You can send me files, editor at panbo.com...but am headed off right now for day with WoodenBoat School nav students....
  • Commented on Coastal Explorer PC charting revisited, with love to WPx
    Thanks, Patrick. Garmin let me know that since software update 4.0, their 76xx, 8xxx, 7x1 and 5x7 units can import GPX files directly, and export them too. I've used both functions with the test 741 and they seem to work...
  • Commented on Coastal Explorer PC charting revisited, with love to WPx
    Thanks, Ron. I didn't know that Garmin once had a WPx-like feature and will also look for it on Simrad. And please keep speaking up about how much you value it. I believe that all the major nav developers are...
  • Commented on Simrad RS35 VHF & HS35 wireless handset, testing pretty well
    Thanks for the clarification, but now we have even more evidence that this is an inconsistent bug. I use scanning a lot with AIS on and never see a reboot, even though your radio and mine are running the same...
  • Commented on Simrad RS35 VHF & HS35 wireless handset, testing pretty well
    Again I'm confused by what you mean when you say "had the AIS function on the same time as the scanning." The AIS receive function is always on, so yes it's on whenever I scan. But the AIS display function...
