Yet another useful feature of radar is finding out where the entity is that
just answered your fog signal.

Leaving the Hudson river a few years southbound in heavy fog something
answered my hailer's fog signal...from pretty close range. Found him on the
radar after some panic and all was well.

Another  very useful feature of radar is the "ranging" function. With the
ranging  rings turned on, you can easily determine quite accurately your
distance to  land or intended destination. (Radar is an acronym for "radio
detection and  ranging"). The ranging function gives an accurate
estimation of distance to  other vessels, buoys, or anything else of
interest -- as long as it is in  radar range.

Also, it is my experience that I often see other vessels  on my radar
screen before I see them visually, even in broad daylight. The  screen
gives a 360 degree analysis of what is out there without having  to
continually crane my neck 360.

My take - it depends totally on where you are and cruise.

I live in the med.
When sailing (various boats, I charter about 5 / year) I often have radar.
I mostly dont use it, and never need it.

I can navigate from Barcelona to valencia, or France, or Palma, or
Tunisia, or ... with no electronics whatsoever.
Over here, there are very few narrow lanes, and no congestion outside
the ports.
Almost 0 rocks.
Almost no one has/uses radar. It4s simply not needed. I have never had
fog at sea in 10 years, ie it4s quite rare.

If I was in the Finnish archipelago, I would find it extremely useful.

Only very very narrow lanes, large rocks everywhere, too many islands to
locate yourself.
IF you are 100 m off-side, You can easily hit a rock and sink.
IF your gps fails, a radar will definitely save you.

I like to sail by night. I find we are comfortable without radar.
Also, over here, non-one navigates at night without lights. The very few
who do are either
a. commercial, and 100% have lights all the time
b. people who know what they are doing, and they have/use lights

Coming to Malta, radar would be very good (not necessary but nice).
Off the cost of Tunisia, at night, radar would be good because of the
illegal fishermen (no lights). Malta (Italia) sometimes as well, ime.

So, for me, it depends.
