  1. PS I only recently learned that Vesper’s Virtual AIS Beacons are being used in San Francisco to mark the spectator fleet boundaries for the America’s Cup: http://goo.gl/auvzJ

    Ben,
    That’s not a Simrad NSS screen for AIS filtering; it is a B&G Zeus Touch screen.

  3. You’re absolutely right, Xavier, and it’s also a Zeus Touch screen via GoFree, which I captured on the Grand Canaria trip. I’m old and confused! But I do think the very similar NSS series has the same AIS controls now.

    How best to present AIS information so the important targets are not missed or misinterpreted or lost in the clutter? Position icons on a chartplotter and position icons on a radar-type display are the typical graphical displays, plus some other displays which are simply lists. All of these have their uses, but none of these is a simple, clear presentation of which targets are most important. That is why there are so many schemes for filtering non-important info from the display. The CPA and TCPA info is not in the graphical displays. It is in the text lists, but it would be easier to quickly grasp in a graphical format.
    Therefore there should be an additional graphical screen which would plot the targets by CPA (closest distance, y-axis) and TCPA (time, x-axis).

    The docs on the Vesper 850 indicate that it can transmit a DSC call to a chosen target, but I see no interface to a VHF to cause the VHF to switch to the chosen channel, nor do I see in the skinny “quick start” a way to configure the channel to be used. Have you looked at this feature?

    I’ve been using Vesper’s AIS WatchMate (WM-670) for the past three years in conjunction with a Furuno FA-50 transponder. Very happy with the usefulness and function of the devices.
    I’ve had occasion to contact Vesper a couple of times and the folk there have been great to deal with. Very customer oriented, responsive, forward looking, and knowledgeable.

    Ben I kinda like the AIS display on my Garmin chartplotter. I can filter out by distance and time and see info like the other vessel’s course and whether our courses intersect. It is all in one place right in front of me. It also places the radar target with the AIS target so you can know they are one and the same target. Nice to have all your data in one place relative to where you are. Of course it is nice to have another device doing the same thing for redundancy.

  8. Ben,
    I installed my Vesper AIS just before sailing direct from Maine to Ireland in 2009. During the crossing, the early warning alarms for targets(up to 30 miles) was much more helpful than radar. At one point, the mainsheet ripped the unit off it’s mount and into the ocean. We turned around, fished it out, dried it off, and plugged it back in. No problem! Later,the rounding of Cape Finisterre in gale force winds in the middle a highway of shipping traffic (10+ targets with CPA’s less than 1 mile through the night)made me a true believer. I love the CPA screen and the filtering features now that I am around Gibraltar where I pick up hundreds of targets. My dream upgrade is one the new units which include WIFI and I can control alarms remotely, and add the target info to my ipad/iNavx charts.

  9. Ben,
    I’m a big fan of the Vesper AIS as well – any idea if they plan a PC application that would enable a user to take advantage of all their advanced menu/filtering options, while using their own charting and monitor display (with AIS overlay)? While the Vision is a nice-looking unit, some folks just don’t have the room for another dedicated display, without the helm ending up like Gizmo’s – no offense!
    Also, I see the Vision webpage claims the following:
    “Routes your NMEA-0183 instrument data over WiFi
    Wind, depth, speed, heading and all other NMEA-0183 data as well as NMEA-2000 heading data is combined with GPS and AIS data and sent simultaneously to up to five devices (tablets, smart phones, computers)”
    Unless this unit also includes a NMEA0183 multiplexer, this would be a pretty neat trick. I’m guessing they mean it supports any ONE of those NMEA0183 sentences, not all of them…

  10. Grant, no offense taken!
    I’m not sure where you think a multiplexer has to go. If you have wind, depth, speed, and heading on one NMEA 0183 stream, as is possible with gadgets like the TackTick NMEA box (though not at high refresh rates), then I don’t see why the Vision can’t mix it with AIS, GPS, and N2K data and send it out to five WiFi devices.
    I’m curious how many N2K data messages the Vision will eventually handle, and I just send a note to Vesper hoping that someone there can field questions.
    Michael, judging from the Vesper App screens I don’t think you can manage WatchMate filters and alarms on an iPad yet, but dare guess that capability is on the roadmap. I notice the neat diagostic screen which even has a VSWR meter for checking your antenna performance (a capability also built into the WatchMate displays).
    Allan, I think the Garmin AIS display is fairly decent, and pretty much the norm for modern MFDs. But didn’t get a bit messy when you went through New York Harbor? Also, don’t you have the CPA alarm turned off most of the time?
    Whereas you are often moored right near me in Camden I imagine you have the same situation where even the absolute minimum settings of time and distance cause an alarm just because we lay close to other AIS yachts, even though all of us are tied up. And then goes off again just when you’re maneuvering back into the harbor even though there’s zero chance of collision?
    I was appreciative when Garmin made it possible to turn off the AIS alarm permanently but it’s hard to call that a feature 😉

  11. jeff says:

    Larry, regarding DSC calling… it does switch channels. You select the working channel when you press the CALL button on the WatchMate. It remembers your favorite so it’s usually just a confirmation. It communicates to the VHF via NMEA 0183. When you press the CALL button it instructs the radio to initiate the call. When the receiving station acknowledges the call, both radios automatically switch channels.

  12. jeff says:

    Grant, it will route all 0183 sentences. If you connect the output of an MFD/plotter/existing multiplexor to the XB or Vision input, then all your 0183 sentences, along with AIS, GPS and NMEA 2000 translations, will be output via WiFi and USB. The WiFi can have many device and application connections to it and they all receive the data stream simultaneously. So, your tablet, phone and computer all get the complete data stream.
    Ben, as you noted it also does this with NMEA 2000 PGN’s too. This requires translation to 0183 sentences and right now it does only heading PGN’s. We are expanding that to include a larger set of PGN’s (eg. wind, depth, speed, etc). Existing owners will be able to just download the new features.

  13. Mark says:

    Ben, I’m confused by your statement regarding the Vespar having a graphical representation of closest point of approach and why hasn’t this view proliferated more widely.
    Every chartplotter and computer charting program I have used in the past 5 years has this function, and it is turned on by default for many of them.
    Predictor lines for both target and vessel can be set for whichever time period one likes, and graphically shows just what the relative positions of the two vessels will be at CPA (ie, will I be crossing ahead or astern of the target).
    Did I misunderstand what you were trying to convey?

  14. Thanks, Mark. Obviously I could have explained better. Please look at those two BARBARA MCALLISTER screens again. The Relative Position at CPA graphic is depicting the future, what’s going to happen at TCPA in 16:59 minutes and about 5 miles ahead. It’s quite different than what you would be seeing at the same time on a standard real time ais plotting screen even with time vectors extended from targets and your own boat.
    Graphics like this have to be individually calculated for each crossing situation and represent different moments in the future so they do not lend themselves to general ais plotting screens. However, I just learned that Vesper has come up with a new way of graphically presenting TCPA on the Vision, because they tried to design the interface so that a user never has to completely leave the overall plotting screen.
    When you tap a vessel it gets a time vector equal to TCPA, your own prediction line changes to that particular TCPA, and added dots at the end of the vectors further emphasize what the pass will look like. More detail and screenshot here in the online Vision manual:
    http://www.vespermarine.com/vision/guide/crossing-situation/

  15. Ben (and Jeff),
    Thanks for clarifying. Yes, if multiple 0183 sentences have ALREADY been multiplexed into a single stream, then I can see how the Vision (with a single 0183 IN)can combine that with other data for output over Wi-Fi. That wasn’t necessarily clear from the features description – and also unlikely that all those disparate sentences would originate from a single 0183 device (excepting, perhaps, an MFD).
    Do you have any insight on my other question (Output and control of the Vespers data and filtering capability to an existing display via PC application)?

  16. rxc says:

    I have to agree with Allan Seymour – AIS information is more useful when it is presented on a chartplotter. And when the chartplotter also includes radar data overlays, you get a MUCH better idea of what is going on around you, especially if the visibility is bad. Two screens, potentially set at different scales, where one has chart data but the other just the AIS data are not necessarily a good thing – it would be very easy to get confused. Also, on the bridge of your trawler, you may have room for additional screens, but in a sailboat cockpit space is at a premium, and a dedicated AIS display does not make sense if the info can be displayed on the chartplotter.

  17. Hi, RXC. I think that overlaying AIS targets on electronic charts is nice too, but unfortunately not a single plotter I know of is as good as a Vesper display at the actual business of AIS-assisted collision avoidance. My intent in the entry was to highlight the Vesper situational profiles and deep control of target icon filtering and alarming that help a skipper make best use of all the AIS info that may be pouring in.
    Please also note that the Vesper WatchMate display was designed by bluewater sailors for bluewater sailors. Hence the very low power draw and excellent night dimming. It’s designed to be run constantly when underway offshore, when a boat may very well not want to run a chart plotter and/or radar, and I believe it’s quite popular for that use.
    Plus I’m not getting how two or more AIS displays could be confusing. In fact, I think it’s fairly common on boats that can afford the space, the power, and the cost. The range a skipper wants for AIS is often much greater than what he or she uses for navigation.
    Then again that could change if CPA/TCPA alarming is improved to Vesper levels. For instance, most boats, say, sailing across Penobscot Bay in fog would like advanced notice that they will be in a close crossing situation with a 20 knot ship. But if you set a CPA/TCPA alarm broadly enough to catch that early on most current plotters you will also generate many nuisance alarms. And you may not want to zoom your main nav screen out far enough to catch the situation early.
    Any plotter or charting program could be programmed to do what a Vesper WatchMate does, I think, but so far none has.

  18. Ben,
    In the open ocean, my plotter does nothing for me. My watchmate tells me exactly which ships I need to worry about and which ones I don’t. When I feel like I’m in the middle of a shooting gallery, I can prioritize the targets and hail the ships with close CPAs. (they usually answer, and sometimes change course for me) These are the things that matter in collision avoidance.

  19. Allan Seymour says:

    Isn’t it nice there are enough options so we can all have what we want . Flexibility is one criteria we should look for in our purchases these days. In building these devices the manufacturer is only limited by his understanding of what’s needed. Programming an extra feature just takes a little code.
    Ben my trips around Manhattan have been made easier by having my own little glass cockpit. All the data in front of me displayed in a easy to understand screen. Just like they are doing in a modern airplane . We came back down the Hudson in a thunderstorm and I was confident I was in the right place going where I wanted and fully aware of the other significant craft. Maybe if I was going to Bermuda I wouldn’t need all of the info I needed in the Hudson River!

    The open ocean situation, particularly on a sailboat, in waves, creates some special problems with nuisance alarms. When your vessel yaws due to a wave, and that puts you onto a collision course, probably the CPA alarm will sound. However a second later you yaw the other way and the CPA solution changes; no alarm. So, it is hard on many systems to mute, or ignore, a ais target which is not even a threat (anymore) yet as soon as you turn your head, it’s back. Dang! And some displays, such as the popular Standard Horizon Matrix radios, they even interrupt whatever you are doing every time that yaw makes your target fall within the CPA window, so once that alarm starts it is really hard to stop it.
    What I need is a list of the targets on which I can highlight one, even if it is not currently causing an alarm, and say, “Ignore this one for a while.”
    That list would also show those targets which have recently, or ever, caused an alarm.
    So when I am at sea on my sailboat and my alarm goes off, loud enough to wake the dead I should add, and thankfully so, I can get to the nav station and, even though the alarm has momentarily stopped, I can see which one it was and mark it “safe”
    As it is now it’s like a video game, can I hit “acknowledge” in the second or two before the cpa changes? Or, on the Matrix, can I get the whole alarm system turned off before the cpa changes back to a threat and the keyboard is disabled?

    I just installed and have been testing the Vesper 850. It really is excellent and seems very accurate. I did have an issue with the DSC direct calling feature not being enabled at 38400 Baud (I use a multiplexer to fork the NMEA 0183 data to my Icom M424 radio at 4800 Baud and my C125 at 38400 baud). Jeff at Vesper was extremely helpful and they issued me a firmware beta to test and I can confirm the DSC direct call feature now works great with my setup.
    I also suggested that they allow you to direct call a specific MMSI number as an additional anchor watch alarm so that if your boat calls your DSC handheld radio when you are off the boat (or at a friends boat) you know the anchor is dragging. I think this would be very cool and perhaps we’ll see this in the future at some point. Vesper’s support seems excellent and combined with a great piece of gear, makes me highly recommend the 850.

    “What I need is a list of the targets on which I can highlight one, even if it is not currently causing an alarm, and say, “Ignore this one for a while.”
    A shameless plug…
    Check out a WatchMate 850. It has the ability to proactively disable alarms for a target. It will also not re-sound the alarm for the same target once you’ve acknowledged it.
    And the WatchMate Vision can be told to remember this permanently for a particular vessel (“I never want an alarm for that ferry”). Conversely, it can also be told “Yikes, I always want an alarm if this vessel is near me!”.

  23. Scott says:

    Does anyone know if Vesper is planning to release their WatchMate app for Android OS soon or at all?
    I am on the verge of buying a tablet and would dearly love to have this but don’t think this alone would force me to go with an iPad.
    Thanks.

  24. Hi Scott, I forwarded you question to Vesper and though they’re closed for the long NZ holiday, Jeff Robbins replied from his boat as follows:
    “The answer is yes, but it will still be awhile I’m afraid. We are about to release an update for the iPad app with radar screen, filtering and more and then we’ll be able to get more time to focus on the droid version.
    However, as you know you can use our Vision or XB with just about any 3rd party app or PC/Mac nav software. You don’t get control & config capability but you can use our PC (and Mac to be released in early Jan I expect) software for that.
    There are fewer droid nav apps though. I saw a very cool new app at METS that will be coming out soon. It’s not fully supporting AIS yet, but we are working with them on it and hope to have much more to say about that soon too. But alas, their first version is also iPad only right now.
    Finally, we missed getting it out at Christmas this year (darn), but we’re putting out an 850 update with a few small goodies like enhanced power-save modes, and external triggers for AIS MOB’s. Should be out in mid-Jan.”

  25. Scott says:

    Ben-
    Thanks, and, inspite of the holidays, Jeff also replied directly to me as well. It is impressive how responsive these guys seem to be – they obviously are very “into” what they do – makes me feel like buying one of their products is more like joining a club! I like it.
    As I replied to Jeff, even though their app is currently only on the Apple OS, it is still not enough to drive me to buying an iPad, so I will likely defer my tablet purchase and focus on upgrading my pc navigation computer instead. Unfortunately, that is a larger issue for my as my hardware is so old (running on Windows 98!) I will have to update my pc first and buy a whole new navgation package and figure out how to interface to my autopilot system.
    Maybe you and your cadre could help me by recommending which navigation software works best in utilizing and displaying the data from the Vesper AIS (obviously I’m thinking towards the XB-8000.)
    Thanks again!
