I think you are doing this the wrong way around.
Choose your chartplotter
first. Radars from the major manufacturers are very similar and they are all very good. I've had Furuno, Raymarine
and now Garmin. Sure you can have an argument about which one sees lobster pot buoys better but we're talking tiny differences in any unit built in the last five years. If money
is no object, you could have a dedicated radar display instead of using the chartplotter - but you've already said money
is an object.
You'll find that you won't be using radar all that often. Chartplotters have already replaced radar for navigation
(e.g. not running into land). AIS
is on it's way to do the same for collision avoidance.
I have my radar on less than 10% of the time I'm underway. And I cruise
. The chartplotter and AIS are always on.
Unlike radar, chartplotter features are very different. Definitely have one in the cockpit
. One below is great too. Find one that has a user interface you like. Better, find one that your wife is comfortable using. Try to get a 12" screen. You'd be amazed at how much easier the bigger chart area makes things.
Next spend money on an AIS transponder (not just receiver). If the other guy has AIS he's going to notice you and see how to avoid you.
Now, if there's money left over, get the radar that works with your chartplotter. Your only choice will likely be whether you want the 18" or 24" size of your chart plotter brand.
