so based on this information from the sh manual i don't really need the transponder ......

.... allows you to contact an AIS Ship directly using DSC....
To help on the above....they won't see you just because your AIS receive only radio allows you to see them. Once you saw them then you could contact them and using the DSC function on your radio give them your location if you felt the situation warranted it but it won't do that without you getting involved.

Like wise if you and I wanted to meet but weren't within sight of each other we could send our locations to each other via the DSC if we both had that on our radios. At the same time no one else would see our DSC location since we didn't contact them directly. The only time anyone and everyone with their DSC radio on will see you is when you hit the distress button on the radio.

If I had an AIS transponder I would only turn it on during times I really felt it was necessary, such as out in shipping lanes at night otherwise if everyone had one and they were on all the time our screens would be cluttered with information we really didn't need at the time and just add more confusion to everyone out there, just my opinion,

Based on the forum discussions and watching on line videos, it seems to be beneficial to have AIS, but not required. I have the opportunity to get it installed and have decided to do so. That way it will be installed by the dealership and treated before delivery.
I really didn't mean for this to go off tangent quite the way it did but sailors are an opinionated lot. Thanks.

I have had an AIS receiver for 4 seasons. I also have radar. I use both when navigating up and down the Chesapeake Bay.

Some friends got an AIS transreceiver a couple of years ago and they swear by it. They said it paid for itself when entering the C&D Canal at 0300 in some snotty conditions and a merchant ship hailed them by name to relate his intentions. They continue to praise it today.

So this weekend at AC boat show I purchased a Raymarine AIS650 at a great price and there is also a $50 rebate from Raymarine.
