20 to 30 amps is the average usage of the electrical and electronic
equipment on my boat use which is probably representative of well
equipped long range cruisers whether they be sail or power. I agree
that on a boat of your size, doing local cruising, power demand is no
doubt much lower. Obviously your power is adequate for your boat - no
problem with that. My original assertion was that most outboards
offer limited battery charging capability. As a rule that is a true
statement but yours may be different.

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.

Correct. It would be a matter of trade-offs between say running the
batteries into the ground vs. keeping watch at critical times. Of course,
the Admiralty Court would determine this after the fact.

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.
