All good points, Rich. It never really occurred to me to use radar to see other boats on the lake. Too many, too fast, on a crowded night to track on civilian radar. If it is foggy, everybody should be at headway speed. Then radar is useful as a navigation tool, on the lake, mostly to identify land masses.
I have seen digital radar on the Intracoastal that will mark larger, slower, targets, and specifically identify channel markers.

I think some of the in and out images may be related to boat size, changing target aspect and vertical motion of both target and transmitter. Digital set ups can overcome some of this.
