We added an EmTrak B951 last spring and it has been great, more useful than radar in most cases (although radar was great the few times we needed it - we were even able to spot humpbacks nearby that we could hear while ghosting along in the fog). A big advantage of AIS is being able to hail commercial traffic by name from a safe distance if we need to. We haven't done any night passages yet, but knowing that we are as visible as possible was a key reason for getting the transceiver vs. a receiver. Our solar arch came with a separate VHF antenna and wiring, so I replaced it with a homemade AIS specific one and it will act as a spare for the masthead antenna as well by just switching cables. Range is good, with lots of visibility to 30+ NM in most areas around here, less in the inlets/fjords of course. I don't have AIS integrated with the VHF radio, but did install a new N2K backbone with the other new gear, mainly B&G wind/dst/compass/gps and plotter. Having not sailed much with accurate wind instruments, I appreciate having them, especially when the wind comes up when going downwind - sometimes it is easy to get complacent with a lot of sail up in 25-30kt in warm summer air, then get a surprise with a windshift or course change!
