Could have done with a no AIS option!

Nasa standalone & nasa engine into Opencpn. What a wonderfully useful source of data.

Good support even if the problem is on equipment from other vendors.

"Other" here as well.
Receiver is built into the Standard Horizon VHF, display is a Watchmate by Vesper. They're AIS specialists, seems odd you would omit them from your poll.

A good watch keeping routine all the time my boat is at sea, all my crew have a pretty good working knowledge of the COLREGs, with the caveat of "If in doubt, give me a shout.", a pair of binoculars, hand bearing compass and RADAR (I do, and so do my crew know how to plot targets even if it does have a MARPA facility), do I need anything else, am I missing something important?
Apart from giving me a name and the MMSI number, what does AIS give me that the above doesn't? Bearing in mind that for me most of time I've had a potential problem it's with small unlit fishing vessels (Morocco, Senegal, Gambia all over the Caribbean) or vessels under 300 GRT that are not fitted with them in any case. The big ships tend to be seen well before they are any sort of danger to me and I take appropriate action to avoid a close quarters situation, considering that most of them are doing 15-20kts+ I tend to give them a bit of sea room, even if it's just to avoid the wake!
Unless you are talking about a transceiver set up, and that's a different discussion.

Digital Yacht transponder; does what it says on the box. Good support too.

Garmin - 'cos it was the cheapest NMEA2000 compatible device with antenna multiplexer I could find at the time.

Instant sog, cog, relative bearing & cpa for ships you haven't even seen yet for 0.1a and couple hundred pounds. Takes all the guesswork out of it. Know if it, s a survey vessel or RAM or NUC miles away. Offshore watch ships alter course to give your more searoom while still over the horizon then know their name to radio up and say thanks. An ais sits quietly in the corner dishing out lots of very useful accurate data for next to no power, whats not to like?

The MMSI alone is worth it - a lot of big ships don't seem to keep a very active channel 16 watch these days - and even if they are listening, it's hard to make contact if you can't see the ship's name.

Plus ROT. (Rate of turn.) Let's you see if they are turning. May be to give way to you.

Back in 2007 when AIS kit was thin on the ground and very expensive, I was at the Hanover CeBIT exhibition on the last day when all the smaller stalls were packing up and a Taiwan company, San Jose Technology, was happy to sell off its stock rather than pack and ship - I bought one of its AIS-2 receivers for peanuts. It's been on board and providing faithful service with its integrated GPS and AIS signals to a netbook running OCPN ever since. I have never subscribed to the class B transponder principle so having just a receiver is fine by me.
Negatives? The fact that despite being two channel it is, like most of the early generation receivers, not simultaneous reception so often the static data sentence takes a long time to show - sometimes when the target ship's name could be useful.
It also was programmed before the class B protocol was finally defined, so while it reports the dynamic data correctly, there is never any associated static data. Even so, still one of the most useful pieces of kit I have ever invested in.

Not installed yet - but managed to lay may hands on a used Digital Yacht one.
Intend to use it with OpenCN on a forces surplus Toughbook which also found its way to me.

SH RX only in the VHF set, quite interested in Brigantias set up which seems to work very well in 3G coverage areas.

Garmin 600 because it suited with the rest of the Garmin kit on board.

Also a Garmin in the VHF. Very useful but annoying that all the wee boats transpond and don't switch off in harbour. It means that the plotter alarms and half the screen dissappeared. Since my plotter is down below but in sight it is a pain to cancel alarms.
