![]() "Shaun Van Poecke" wrote in message ... 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.... |

![]() "Scotty" wrote in message ... ''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. :-( |

The USA uses the IALA system of buoyage. Here's proof: http://www.sailingusa.info/basic_navigation.htm 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. http://www.sailingusa.info/titles/co...ose_dkblue.gif Cheers, Ellen |

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. |

Don't ask how I know that.... 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. Shaun |
