As a sidelight to this discussion, I wonder how many here turn their radar on to calculate and mark other boats and shoreline or points of reference. We have poor ability to judge distances for one thing. And chart plotters only give you a good theory as to where you are. I found the radar handy on a few occasions, even in daylight, and alsways in poor visibility, as it was already on anyway.
I do it all the time. I usually set up a VRM just touching the closest objects so I can tell at a glance if and how we have moved. And if the wether is unsettled, I leave it on all night so I can check it at any time.
