Well, I sail in front of Toronto, where there is a pretty well
continuous loom of lights from 20 miles east of the city for 60 miles
west to Hamilton and beyond. Radar in conjunction with GPS helps a
great deal in conditions when the night pilotage is confusing due to
TOO MANY signals.

It's a helpful adjunct, particularly at night, but not restricted to
then. In addition, it can provide an early warning of approaching line
squalls, a great help during hot summer weather hereabouts.
