No, I agree that it didn't seem likely, and perhaps by the time that
all navaids have lights, some of them will have AIS. On the other
hand, too much clutter on a display can be a bad thing sometimes.

Or that, after you had a car accident, the person suing you would have
the computer chip memory from your GM car seized and read under
discovery to prove that you were going slightly over the speed limit
when his client ran the red light and you are therefore at fault.

It's difficult to envision a time when all navaids have AIS
transponders installed, don't think it will ever happen except for
the
very biggest/most important. Look at how many unlighted navaids we
have now, which is very low tech/low expense by comparison.

If you have a good quality color radar with all the bells and
whistles, it is not that difficult to get the information you need.
My Furuno for instance has the ability to overlay the chart and
radar
image on top of each other, and keep it aligned with your heading.

WOW!! I am blown away by that site......had no idea such an
application existed, thanks Larry! Any more like that??



There's quite a few, but lesser, AIS sites like www.aislive.com who will
let you peek through the delayed window at the products they sell. Do a
Google Search on "AIS Live" and AIS and Google will find them for you.

Wrong concept. It matters not WHERE the AIS signal comes from, only that
it is in range of your receiver. To plot all the navaids and
obstructions for the entire area, say Charleston Harbor, only requires
ONE, centralized transmitter, high up on a tower for maximum range. That
shore transmitter broadcasts all the data for all the navaids and known
obstructions from a database kept up by the local authorities, in our
case USCG. Every time a bouy is moved, the database would be instantly
upgraded directly from the terminal on the bouy tender, say over Marisat
or a military link. The very next beacon transmission from the area
shore station, you'd see the bouy moved to its new location on your
boat's AIS transponder, not 4 months from now when a notice to mariners
was ground out by the bureaucrats.

The navaids and other "targets" do nothing and have no AIS equipment at
all.....

Yes, you see "something" on your screen, a blip. On AIS you see:

Name: Vaky Junior
MMSI: 377203000 [VC]
IMO: 7532650
Callsign: J8B2518
Speed/Dir: 15.2 kts / 262° W
Status: Underway
Dest: Portbury
ETA: Aug01 10:30
Type: Cargo (70)
Details: Bulk Carrier
Size: 245m x 32m x 11.8m
Tonnage: 41300 gt
Built: Oct 1983
Received: 18:32:28 31 Jul 06

which I just copied/pasted from Liverpool AIS live as I type this. You
know WHO he is, WHAT he is, WHERE he's headed, WHEN he's going to get
their, WHAT his course and speed currently is, HIS radio call and MMSI
for DSC calling.....and, armed with 41,300 Gross Tons, you'll keep a
respectable distance not available on Mr Furuno's green blob. AIS data
also tells your plotter his exact lat/long not listed in this listing
from the webpage so it can VERY accurately plot his crash potential MARPA
on the radar is only guessing at, frequently making gross errors if your
boat's rolling around a lot and the target's going in and out.

Just no comparison.....

"Coast Guard Charleston, we have AIS transponder aboard and running.
Please relay this information to the helo and cutter headed our way."

Not only would they have your 406 EPIRB data from the overhead satcomms,
but they can look at their AIS (assuming they ever get the damned things
installed) and plot your exact position for intercept course to help you.

I think AIS is FAR more important to marine safety than GMDSS will ever
be.....operational as well as emergency....

The sooner the government gets a constellation of AIS SATELLITES in LEO
polar orbit, the better!....

I believe it is called RADAR.


If you got a Radar, that goes around corners, you need to get to the

I agree that AIS is way cool and gives you a lot of information. A
*good* radar gives you a lot more than a blip however. For example:
Speed of target, Course of target, CPA (Closest Point of Approach of
target), TCPA (Time to CPA), Target Lat/Lon, Target Course/Speed
Vector, etc. About the only thing missing is name of the ship but a
quick call on channel 13 will get you that.

All for well under 10 boat bucks, and relatively easy to self install.
Even the admiral likes it and she is not easily impressed by
electronic gear on a boat.

Musseler ( yeh, I really was a clammer)

Muesseler,

I think you have done a nice job putting together your website. You are
simply trying to put together information for people to share and learn
from. I myself have put together a website, and the biggest rule that I
always tell people that I work with is, you have to assume that all who
visit your site; the last thing they want to do is think. make things
as intuitive as possible...believe me, its not the easiest thing to do.
But you have done a nice job with your left hand navigation menu. You
can get to the "meat" of the site most of the time within two clicks.

One suggestion I have is to spruce up your homepage, throw a little
color in, possibly a picture or two. Your homepage is your landing page
and studies show that you less than a second to capture the attention
of a passer through.

Nice job overall though, if you would like to talk more, I would be
happy to. I think you have a nice idea with you virtual voyager, have
you played around with Google Earth??

Best,
Brandon

Thanks Captain B, I need all the help I can get.

Yes, I tried to use Google Earth, but my pc only has 128M memory, and
they reccommend 256 minimum, I think. I'm holding off until next year
when the 64 bit machines with MS Vista come out, and then plan to get 4
gigs of memory, which I hope will carry me another 5 years. I really
think I'll like the Google Earth stuff more, and they seem to be using
XML much more than MSN, which I need to learn more about, but I like
what I've played with in XML so far. As you can imagine, MUCH much
more can be done with the Vir Voyagers, but I'd rather not have to slow
them down with database access, which is where XML may help...I think.
I just hope that with the new 64 bit operating systems, the client
side code size limits increase greatly, to support larger javascript
arrays, XML, etc., and database access may not be needed. I don't
have the money to put into anything fancy like Coldfusion & SQL, altho
I've coded in it and it's great, so if db's are needed, it'll be PHP +
MySQL. If MS Access comes with Vista (at no extra charge), I've coded
in it and Visual Basic (VB3) many years ago, and if Visual Basic comes
for free (no extra charge) I'd consider going to VB & Access.

Microsoft seems to think all programmers are wealthy enough to just run
out and buy the latest software updates they come up with, but I can
tell you, IT AIN't SO.......my wife and I make less than 1/3 of what I
did make before retiring, and freebie software is all I can use.

Thanks again for your input, there are so many things to take your time
these days, its hard to get anyone to actually go thru a newbie
website.

Considering how delayed Vista/Longhorn has been and how reliably M$ has
missed announced release dates, I expect you'll maybe see Vista in
2008, and it won't be even minimally reliable until '09.

I get paid quite well to support M$, but have *no* M$ products on my
home machine, as I just want to USE it, not have another career of
making sure I'm safe at home.

Apple sold machines using Core Dual Intel chips *before* any Windoze
supplier did, never mind that Apple performed a complete OS change in
the process.

Good luck waiting for a reliable 64-bit M$ OS.....
