The best way to be seen on someone else's radar is to have your own radar
turned on.

I like it, I use it, but I frequently see problems with reception

Yah, like you really need it driving a little pilot boat in and out of a
harbor in a marked channel... Lame, otn, lame!

Great idea Matt,
That's fine if you have radar which a lot of yachrts crossing the
oceans don 't. It's also fine so long as you don't mind turning the
engine on to charge the batteries. To have the radar on 24x7 means a
lot of battery charging even if you use the sleep/sweep function that
some have. There are other drains on power - eg navigation lights etc.

Technology is there but in practice it may not be practical.

I wish the technology with fuel cells would advance far enough to be
economical to address applications of this nature.

What type of fuel cells are you talking about? The fuels cells most
people refer to convert hydrogen to electricity. But the hydrogen is
either taken on as fuel requiring high pressure tanks and hydrogen
filling stations everywhere, or its created with electricity, and thus
works just like a battery. There are maybe reasons why this works for
cars, but it isn't very practical for boats.

Quite simply, if you are on watch you can glance at the radar when you
do your "stand up and slowly scan the horizon 360 degrees with your
peripheral vision" The oncoming ship may not see you at all or even be
aware of your presence but at least you can take avoiding action.
Also, if you have a guard zone set, an audible alarm will warn you of
approaching shipping.

I do not want to place my life in the hands of someone I do not know
and whom I cannot ensure is attending diligently to his instruments
and thus I take sole responsibility for not being run down by a larger
vessel.

I have installed external piezo alarms (a few dollars each) of the
loud lazarus variety (awaken the dead) on all of my instruments - GPS
for anchor drag, wind for increase above a set level, depth and so on.
I am in the process of installing a seatalk one for the Raymarine
radar as the unit's internal one is not loud enough. I couldn't do it
for my last solo sail as it needs a "box" to attach an alarm to.

None of this is intended to allow me to armchair sail. They are merely
an attempt to make life easier and longer. At anchor now for years
with a 60lb anchor down on 5:1 depth of chain, I can sleep more
soundly knowing that should the wind turn or the anchor drag, I will
be awakened from the deepest sleep by a strident alarm that can be
heard on the other side of the planet. It's amazing how much better
one sleeps. Note - I test this alarm very often. When it does go off
in the night I don't even have to think. My body leaps out of bed and
heads towards the deck, followed by my mind shortly thereafter. Anyone
who neglects to add a $7 peizo, available from any electronics shop
(make sure they are 12 volt) is avoiding very cheap and very easily
installed insurance and peace of mind.

All understood, Peter. My question was directed at Matt O's statement "The
best way to be seen on someone else's radar is to have your own radar
turned on."

You forgot something very important. How about a low-voltage alarm in
case your battery goes flat in the middle of the night from all the
excess draw from all your electronics and alarms? ;-) I suppose I use
different tactics. My Allied Seawind 32 only draws four and a half feet.
I use this to my advantage and always try to anchor in shallow water
where a ship couldn't run me down if it tried.

Bull. The commercial boats don't mind knocking a few of us over. To
them, we're sea trash.
