Old charts can still be used so long as they are accurate. Keeping them

up
to date with all the notices to mariners can be a full time occupation in
itself if you have a lot of charts, but its rewarding work. You can
download the notices to mariners digitally now, or if you have time, you

can
go to your local maritime office and sit there in luxury with a cup of
coffee and update your charts there.


Just don't get behind with the work. It is frustrating to start to catch up
with a heap of Notices in front of you and spend time plotting,say, the
position of a wreck obstructing a channel, and then find three or four
Notices later that it has been removed and you have to erase all your
previous work. Don't ask how I know that....

''lights change characteristics''

how so?


Well ,around here there are lighthouses that were built on convenient
islands but have more recently been replaced with lights on concrete pillars
placed somewhat nearer to the channel. These can have different
characteristics to the disused ones.
But lighted buoys are more likely to be shifted and changed. There was a big
change of light characteristics in most of the world many years ago now when
the IALA system of buoyage was introduced internationally.
The USA did not sign up to this so all your channel buoys are opposite hand
to the rest of the world and AFAIK you do not use the same cardinal light
system to mark offshore obstructions that are familiar elsewhere. :-(

More bullocks! The USA uses the IALA system of buoyage. Here's proof:

Oh, BTW, US sailing is trying to keep people from stealing their pictures. So lame!
I like the background with the compass rose. Not only did I steal it but here's the link so
all of you who want it can steal it too. Their little protection scheme is so dumb even a
blonde can get around it.

Not bullocks! The IALA simply recognises the difference.
IALA region B covers only the Americas, Japan, S.Korea and the Phillipines
and in region B the lateral buoyage system is different to all the rest of
the world which is region A.

Good wiggle there, Edgar. First you said the USA didn't sign up for the IALA.
But they did. So you were wrong. Then you admit the US is a signatory of the IALA
but they use IALA-B along with half the world. Tell me Edgar what makes IALA-A
better than IALA-B? Seems to me they are both equally correct because they are
both sanctioned by the same treaty.
It's the same as Yanks saying Brits drive on the *wrong* side of the road. No, it's
not the wrong side. It's just an opposite side as we drive on. Both are equally lawful
and acceptable.... You can't look down your nose and say one is stupid and the other
is smart.

Cheers,
Ellen

I did not say it was stupid or unlawful but I think it is regrettable that
the USA did not comply because the other countries in 'B' would then have
had to follow suit and we would have had one uniform worldwide system.
So I think that IALA, needing to publish something that would be studied by
mariners worldwide, had no option but to create a 'B' category because
obviously their publication could not leave USA out.

Its a learning process just the same.... the person with the right frame of
mind can actually find it fascinating to watch 10 or 15 or even 50 years of
history unfold right before their very eyes, and to make judgements on how
things were handled. Rather than say, pulling your own hair out with your
hands to the point you were left a drivelling bleeding mass of quivering
flesh.
