Buy Raymarine AIS500 or buy £800 of Raymarine shares?

AIS500 I applaud Raymarine for having brought this unit out earlier this year, it is good product marketing and market positioning (pun intended:-)

But if you already have a reasonably sophisticated set up, and already have AIS, is it worth spending £800+ to upgrade to this unit?

Here is my take on the list of features for the AIS500:

Feature Comment
* Class B AIS Receive & Transmit Good – and so do all the competition at this level
* Dual Channel AIS Monitoring Ability Good – and so do all the competition at this level
* Targets displayed on chart and radar screens Clever – but I normally overlay radar on the chart plotter or display AIS targets on the chart rather than the radar which could be very confusing if not misleading due to the different methods of target acquisition
* LED Status Indicator Good – Surprising omission on so many marine electronics and very annoying when there is no status light and you are troubleshooting.
See my posting here on the RaymarineAIS250
* NMEA 0183 – Compatibility with Raymarine A, C, E and G Series Good – the great majority of Raymarine users must be on C series (or lower) still.
* Buddy Tracking via Raymarine MFD – Distinguish favourite targets (MMSIs) from others by adding to favourite list Clever – but is this really needed – oh ok could stave off boredom in some situations to switch between “favourites” and “all” targets. In between calling your buddy on the radio…
* Silent Mode – Turn off transmit function during tournaments or races if you do not wish to be seen. Good – But only if you expect to be sailing in regions where piracy is possible – not really a problem in the Solent – yet!
I did refer to this as a good thing in my posting here:-)
* Built-in NMEA multiplexor Not Good – I have a principle of using separate dedicated pieces of electronics instead of multifunction devices ion this situation. A faulty multiplexor can take down the whole backbone and all links between devices I would not want to troubleshoot that with a device that was doing so much else as well.
See my posting here on multiplexors.
* VHF Splitter – No need to buy a separate antenna. Utilize your existing VHF antenna and cable. Not good – don’t use splitters on your VHF cable!. keep the radio and its aerial as separate as possible. Yes I know that DSC has meant connecting the VHF to the NMEA circuit – but just don’t mess with the VHF aerial. This is a critical lifeline. Install a separate VHF aerial for AIS on the pushpit IMHO.
* Includes dedicated external GPS antenna (16 channels) Not good – as per comment above. Keep the GPS separate, you probably already have one, get another one for backup don’t get one built in to another multifunction device.
* Configure via PC Software
* Software upgradeable through PC and RS232
Ok – but why use serial connections and then very probably a serial to USB convertor when you can use high speed USB. Most modern laptops don’t even have serial ports
See my posting here on serial / USB convertors

I last did a quick survey of transponders (or are they transceivers) in June 2008, but I have held off updating this since I believe that we can expect another revolution in AIS for small boats in the next 6 months.

On that basis I would not buy the AIS500 now, if you already have AIS – if you don?t – then it is a very capable unit with the benefit of a back up GPS.

If you already have AIS and you want to spend £800 buy Raymarine shares, if you made 30% profit when Garmin buy them, that would be an extra £240 to spend on the next generation AIS – then again shares can go down as well as up:-)

    Hiya, I’m starting up a blog website and I’ve started making somewhat varied articles. Would you mind if I write about this blog? Obviously I’ll give you and this site full credit.

    "Funny" thing: You cannot switch to silent mode with the software included in the package. Both, the hadrware and software Manuals telling its possible, but well, its not 🙁
