Re: Finally saw the 35 Ericson
Actually, AIS is more useful coastal than offshore. Coastal is where barges are coming around blind river bends, commercial ships are suddenly making large turns, one encounters crossing situations with multiple ships, there is less freedom of movement for all involved, etc.
Offshore, AIS is nice, particularly at 3am on a dark night, but its advantage is usually only in giving one a larger margin of time with better data to avoid a single ship in open water.
We have a Vesper XB8000 black box unit with no display. It is connected to our plotter, which displays all the targets there, but also has a wifi server that puts all of the data on a tablet/phone. Vesper has a good app for using these data that shows crossing situations in great perspective. We usually see the targets on the plotter, and if there is going to be a crossing situation, we pick up our tablet or phone to negotiate it using Vesper's app.
The Vesper units all output 0183, so you will be able to connect them to your plotter. The display on the Vision model essentially runs the app software, but at greater cost than the black box and app. It is good if you don't like using phones/tablets for this stuff, and can mount it where it is useful to you for navigation.
I must say that the Vesper AIS was one of the best things we have added to our boat. Behind the lithium batteries, but competing closely with our high-output watermaker.
