autopilot

I have to agree with Boris on this one. Over lay is always on and running regard less of the weather. it really helps pick out fast movers in the sun and glare around here. boat s that I would not have seen other wise on clear days. Going back and forth from map to radar just sound useless to me. But as with most things in life is what you learned first that works best for you.
 
Amen, Radar is always on if the boat is away from the dock, and it is on a plotter overlay, generally in the 3 to 6 mile range, beyond that, the AIS is showing me what to watch farther out.

I have the radar on at all times now too. How does the AIS work?

A boat with AIS transmitter (A or B) transmitters the location, the speed, course over ground, and vessel name at a minim. The value of this is that the message of AIS comes in from beyond the horizon of the radar, and around corners to some degree...(It is line of sight, in the VHF spectrum, but being digital, the range and "clarity" is better than voice.)

The reason I use radar without overlay, is that I began with radar long before chart plotters, and thus learned to superimpose mentally the radar image over the paper chart image. At times I still use radar plotting boards. In the modern boat the two images are next to each other and at the same scale--making it even easier. You don't have all of the clutter of radar on the chart (which may allow you to miss some chart information.--to me this is distracting--as is the AIS data is on the primary chart. Perhaps a little more difficult--but I believe it gives me more positive information, and less false information. For example, I have watched DEA boats "hide" in the radar shadow of a buoy. I have seen one echo, and assumed it was a buoy--when it was a boat in close proximity. When you are at closest ranges, the Radar will show slips, boats, pilings etc which are not on the charts.

I find it easier to do MARPA and CPA with the plain radar. Range and bearing are always your friend. As noted some newest radars do differentiate boats moving toward and boats moving away, by color. To each his own.

Dr Bob will my existing equipment receive ASI transmissions or do I need to buy something?

Ken, I don't know what radio you have. If it is the S H2100, 2150 or 2200, The Icom 605 or 506, Garmin; 210, RayMarine;70, the Lowrance Link 8, Sinrad: NAIS 500, RS and RE 35, RS 90, B & G V50, Uniden UN450, you have the capability...(I may have missed some lesser known brands. You can add any number of AIS receivers stand alone, or transceivers class B stand alone. Milltech has stand alone receivers for $189 on up. Some have "radar like" screens. Vesper also has receivers. Digital yacht has the cheapest at about $160 for a stand alone receiver. All of the major chart plotter manufactures have stand alone receivers.

Sorry Dr Bob. I have a 2017 Garmin 741xs with the RADAR package and just added the 1040xs.

Ken , a radio receiver picks up the AIS data. Either of your Garmin chart plotters will show that information, if the radio (listed above) has the receiver which picks up The AIS information.
 
Like Bob, I also like using my Radar in it's own screen. Yes, I do frequently have it in the overlay mode, but when it's on it's own screen it shows targets much more clearly. (In overlay, it's somewhat cluttered and the targets don't stand out as well.) In reality, if I am running "blind", I will switch back and forth between overlay and radar. With past experience it's not too hard to tell if I'm looking at a moving target, or a stationary one. And the bottom line is, the target is not on a collision course with me! Colby
 
Trick for overlay that you may not be aware of. You can adjust the opaqueness of the radar. This allows you to see targets and chart features at the same time. Its a menu item in all MFD I have used. Some times you have to dig for it.
 
From raymarine guide book for MFD

Enabling radar overlay
With the radar turned on and transmitting, with the chart application
in 2D view:
1. Select Menu.
2. Select Presentation.
3. Select Layers.
4. Select Radar.
The radar overlay opacity slider bar control is displayed showing
the current opacity percentage.
5. Adjust the slider bar to the required opacity, or
6. Select Off to turn the radar overlay off.

Got it! I'm on it!
 
I have the Icom M324 Vhf Radio Black IC-M324 01 which has Common NMEA Interface
When receiving DSC information from another vessel, the IC-M324/G can transfer it to a navigational device via NMEA 0183 connectivity.

and MA-500TR AIS transponder compatible.

Which I think means I need to buy one of these http://www.icomamerica.com/en/products/ ... fault.aspx

I was out on my boat this past weekend and getting used to the RADAR. It's my first boat with RADAR and I'm really really liking it! It's amazing how many boats it sees that I don't. I'm trying to spot each boat as I see it on the RADAR and it's amazing!
 
The Icom MA TR 500 is a class B transceiver--it will both send and receive AIS information on its small screen. The Icon Transceiver is a good unit.

If you don't want the full transceiver and just the receiver there are going to be less expensive options. For example if you want a second radio, which has the
AIS receiver, plus hailer/fog horn, the Standard Horizon GX 2200 is a little over $300.
