marpa

I sent some time on a 165' research vessel this November in the fog. Anybody using ARPA/MARPA or AIS? And along those lines which charting software do you (With arpa, ais) do you use. I'm still with OSN and was looking at rosepoint/chart navigator pro and RNS. -Regards, Ethan

I've been putting together a Raymarine Radar/chartplotter system out of bits and pieces over the last few years. I'm starting to tie it all together and needed a few bits of information and your experience. I've asked for a few parts in this thread...
