Damn! That's some soup.I almost never used the radar during the day when we were on local waters. In fog and/or after dark--ALWAYS.
Take a close look at this first picture below. I was entering the bay where my old yacht club was. I'd been in and out a bazillion times but never in a fog like this. Can you see the levee ahead of me, and the tree that's on it? The levee is only about a boat length in front of me. Now look at photo #2
I took this photo before the one above. The black line extending from the boat is a "Lubber Line". It shows where the boat is pointed. The red line shows the actual course of the boat. They're different because of about a 2kt current that's on my starboard side. The purple blobs are land masses and they're offset a bit because of the delay in the radar sweep. On this pic, look at the corner of the display. My SOG (speed over ground) is .12kts. Just barely creeping ahead. Ya gotta love a good radar display and also knowing what it's showing you.
If it wasn't for that radar and you knowing how to use it.....
