'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.


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.
