Spoken like a powerboater who "needs" radar on a sunny day.
You only need to run it once in a while, and understand how it
works. Most power boaters run it constantly for ego gratification.

The point I'd stress, is "practice". Don't just use the radar when
conditions are bad. You need to use it frequently when conditions are
good, so that you learn to interpret what you see .... probably the
biggest problem most recreational (and a lot of professional) boaters
have using radar.
