[PUP] AIS Drama

Sun Aug 12 04:25:53 EDT 2007

Travelling north to the Whitsunday Islands in Australia close to the end
of a 540 nm not stop passage, our radar came alight with a field of
green AIS targets anchored in a zone off the port of Mackay, about 10 km
out. These were ships waiting to be loaded up with coal, and all ships
were tightly packed, and none of course were underway.
We decided to leave them to sea and head almost due north when clearing
the zone, but found red radar targets continuing on as the AIS maxed out
at 70 targets. We decided to bite the bullet and thread our way through
the Armada. Big mistake was not to turn our AIS transceiver off when we
did it as our VHF went mental with chatter about a very nimble target
moving through the zone. It was like a Chinese laundry declaring it had
just run out of washing power.
On our way south next month we will leave them well to shore to save
some angst.

John,

Next year, we plan to leave Hawaii headed across the Pacific.  High
on our list of priorities is getting two of the Xantrex battery
chargers for dealing with European power.  We are looking at the
Xantrex XC5012 multi chemistry battery chargers.  They handle input
voltages from 100 to 260 VAC and can be configured to charge our AGM
batteries.  All of our appliances would then be run from battery
power through the inverter with no adjustments.  I'm still working
through the details on how to run the air conditioning yet, but I
have some good advice.  Below is the URL for the Xantex (sorry I
don't know how to do the little URL thing).

Thanks to Bill's help, this is a much more manageable URL for the
Xantrex charger:

Recently we have found ATON's that are AIS beacons. These have a very
long
range....we've seen them at 24 miles so far and they give you their
exact
location within 10 meters. Very good news I think as an additional nav
aid.

We don't seem to find that the software in plotters or the nav programs
seem
to handle them very well. They don't treat them as "ships" so you don't
get
a range and heading from them unless you move the curser to them.

Has anyone encountered these yet and if so does your nav software treat
them
as you would expect..or perhaps it doesn't even "see" them.

As always YMMV..

I've seen a number of things that report as "Base Stations" on AIS.
Not sure it that's an ATON. I've seen them at ranges out to 60 miles.

If I recall you have a Furuno AIS. Is this true or is my CRS acting up
again?

We have been told that these AIS units may be replacing lighthouses if
they
are on land and leading sea buoys if they are in the water. How much of
this
is true seems to be hard to find out.

In the UK there are many many of these "base stations". More to follow
according to a UL friend of mine. The new "smart buoys" will be equipped
with SIS transmitters to help their identification and also as an ATON.

Coastal Explorer only identifies them as "base stations" with their MMSI
numbers, location and accuracy of location. I have an earlier version of
the
Captn which does a similar readout, Sea Clear also. Sure would be nice
if
the software computed the range, bearing, CPA, etc as it does on ships.

I can see lots of great uses for all of this....looks like the software
folks have to catch up with it.

Cheers

How about a concoction of regular household ammonia cut with two thirds
of
water. Put it in a squirt bottle and hold off an army. Unless they are
armed
also. Rumor has it that it will stop an attacking dog in his tracks and
will
temporarily blind it just like pepper spray. I hope I'm right about the
dilution formula. Maybe good against bears also.  Maybe some one will
try it
and comment   ; )
