Full AIS transponders.....the sooner, the better for everyone.

If you can afford a yacht, you can afford a small AIS transponder. Noone
HAS to die. Ouzo would have had the same size target on the AIS screen in
that ferry as a big aircraft carrier. No need, any more, to rely on some
plastic reflective ball to make you a tiny blip on someone's 1957 tube
radar screen, fading in and out as the mast lays over. EVERY yacht going
to sea in this traffic needs a full AIS transponder running 24/7.

There's too much big traffic, today, to go on without it.

Larry,
Great idea. I have been in situations where the ships can visually see
me but I do not appear on their radar screen - sea state and waves
etc. - I have the old metal "forget what it's called" aluminium sphere
permanently swinging at my cross trees.

Any idea what they cost and is there a fee involved or do you the
American tax payer foot the bill as you so generously do for GPS?

cheers

AIS is not a "silver bullet". Although many ships are transitioning to
"ECDIS" wherein they will end up having a screen with a chart/radar/AIS
overlay, it is not all that common yet.
In most cases you are still dealing with a seperate AIS screen which only
list the targets and is only usefull if you have some reason to look at
it..... so .....if they haven't seen the target visually and/or on radar,
they may not check the AIS to see what's about/around.
Prudence would say visual..... check the radar for targets with and without
AIS, check the AIS for targets missed on radar.... and back to
visual....i.e., with each new system you improve your lookout
capabilities.....but only if you use them.

But AIS adds an extra dimension - A smaller vessel that feels at risk
of not being noticed can now hail a large vessel by name and ask if
they are being tracked. That would make a huge difference when
crossing busy lanes.

I think it's definitely a net positive, except for the cost. I suppose it'll
come down at some point.

The ability to call a vessel by name is probably one of it's greatest
benefits.....but knowing the name and then getting an answer to a call is
still not guaranteed to be successful.
I like it, I use it, but I frequently see problems with reception while
using it and I stay ready to try different channels while calling and try
to watch my "Boston" accent and tendency to talk fast.

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

Class A AIS transponders and software also ALARM to wake up the watch to
the crossing/collision situation. He doesn't have to be staring at the
screen all night to notice you....LIKE RADAR.

A good radar has a range alarm as well Larry.

The whole point otmbrd is making is that all are just tools for you
and your lookouts.

Now if a ship load of retards are sleeping, not maintaining a proper
lookout, not applying the tools properly.... then none of it matters.
Nadda...zip it's just high dollar usless ****.

Thats all we need......another law to sell products that you do not
really need IMO.

Gotta agree with Joe here.
