You probably know this already but per the COLREGS boats equipped with
radar are supposed to use it:

Rule 7

Risk of Collision

(b) Proper use shall be made of radar equipment if fitted and
operational, including long-range scanning to obtain early warning of
risk of collision and radar plotting or equivalent systematic
observation of detected objects.


'Proper use' does not compel you to have your radar going at all times.


Wrong! Look at the way the sentence is written. What it's really saying is
this: (b) Proper use shall be made of radar equipment if fitted and
operational. Proper use includes long-range scanning to obtain early warning
of risk of collision and radar plotting or equivalent systematic observation
of detected objects.

Now, I ask you, how is one to do long range scanning, radar plotting or
equivalent systematic observation of detected objects if the system is
switched off? The answer is you cannot, therefore you are in violation of
the rule.

No, it is cleat that if radar is installed and operational it must be used
for the above when underway.

I disagree. It depends on circumstances, and you have the right to make a
choice.
If you are in a yacht going 4-6 knots with several miles visibility it is
pointless to keep on long range scanning.
If you are in a VLCC with six miles stopping distance it is quite a
different ball game.
But Jon is quite correct in his post.in that if you get it wrong it is not
going to look too good in court

I disagree! If you are in a yacht going at 4-6 knots it has little bearing
on a ship going at 25 knots on a collision course. At those relative speeds
you have less than twenty minutes to sight it, plot it's course and take
evasive action. You can look all around the horizon, go below to prepare
some hot coffee and right about the time it's perking away you'll be run
down.

If you are in a VLCC with six miles stopping distance it is quite a
different ball game.

But, YOU can see a VLCC on radar much easier than he can see you. In a small
yacht the radar is more defensive in nature. If you have it you need to be
using it.

The big ships have bigger, better radars. This mitigates the
difference in targets size somewhat.

Correct. You'd be better served, at least with commercial traffic which is
typically the situation, to use AIS.

When someone falls over the side you put the rudder hard over, leaving
the engine alone. You make a circle a mile in diameter and are down to
three knots when you get back to the spot.

My position is that if the radar is turned off, it's not "operational." :-D

Weird position, Karin!

If I were to ask you if you had an operational hair dryer would you say no
unless it was plugged in, switched on and blowing hot air?

If I asked you if your dish washer was operational would you have to schlep
your rear end into the kitchen to see if it was on and washing dishes?

If I were to enquire if you had an operational automobile would you say no
unless your were sitting inside with the motor running and the transmission
in gear and the emergency brake disengaged?
