For a sailboat definitely the B&G autopilot which has the legendary Robertson AP blood in itís veins.
For radar and chartplotter you have to select the same brand as itís the same display unit. I went for a B&G 4G radar (Simrad is the same unit but has a shorter cable, i.e. is for motorboats). You can get much better radars with Doppler technology etc. from either brand but with AIS
today the role of radar is reduced to smaller range during fog
, tracing squalls and the occasional target without AIS
. To keep things simple, a 4G Radar fits pretty good.
Also, you can run the 4G Radar with only OpenCPN
so without chartplotter. You can even do the setup that way.
I choose the cheaper B&G Vulcan 9Ē display/plotter because we use iPads and iPhones for charts
as well and the plotter mostly for sending course info to the AP and instrument display. I use the charts
to quickly point to a waypoint for entering it and overview.
