Stus-List Fw: (no subject) now AIS

Joel, I knew about the time lag, but wasn't aware of the voluntary nature of the app. I will say that it has been dead on tracking the tugs going up the Nanticoke when I'm duck hunting!

Chris, 


Marine Traffic depends on volunteers to relay data. They say there can be a lag of up to one hour. While it was pretty accurate on the Chesapeake last summer when I played with it and great for keeping track of a ship, I would not want to rely on it for navigation.

On a night time trip up the Bay a couple of years ago, the AIS receiver was a blessing. There are so many lights on shore that it is almost impossible to pick up the tug towing or pushing a barge barreling toward you.......

On the Chesapeake most private vessels to do NOT have AIS. There is enough commercial traffic to make it useful. 
I ordered the SiTex transponder and splitter over the weekend. More wires and cables.

Mike, 


Did you want a transponder or just a receiver? If just a receiver, consider a VHF radio with AIS. I have a one interfaced with my chart plotter. 


Also having an AIS can give a false sense of security. Not all vessels have AIS.

Thanks to those that responded. I’m now convinced I want an AIS. The problem is which one. It will be connected directly to the pc chart plotter. The Raymarine, Garmin and SiTex (new to me) all look promising.

No I will connect it to the plotter.

Joel, 
Is this the SI-TEX unit that you were looking at? 
http://www.si-tex.com/index.php/product-information/ais/sas-300-ais-class-b-ais-transceiver-detail 

Although I don't have any of their hardware, I like the SI-TEX brand. They seem to occupy the "value" space. Value, like free wind, = good. :-) 

Full disclosure: I'm just a day-sailor who rarely ventures outside the mouth of the St Johns River in Florida. Despite this, I bought an MilTech AIS receiver 6 or 7 years ago because I thought it was really cool and relatively inexpensive. It once picked up the signal from an old tugboat in for repairs at Green Cove Springs. w00t. 

As for AIS (receivers), do folks think that a radar-like display of approaching targets is OK or even perhaps optimal? 
Or, is it be important to be able to put the nearby boats in the context of a chart? 

I know that many chart-plotters can interpret and display AIS data and predict potential collisions. But, might this be a good case for having a standalone unit, dedicated for nearby "situational awareness" - kinda like radar I suppose. Probably depends upon one's situation. :-)
