IALA B Buoyage

My understanding is that it's because our American friends have always taught "Red Right Returning" (ie red buoys on your right as you come in to harbour) and weren't prepared to give that up just for the sake of one consistent international agreement.

Remember, it's only the colour that's different, it's not a complete reversal. Lateral buoys are the same shape in IALA A and IALA B ... flat tops on the left and pointy tops on the right when travelling in the direction of buoyage

I think the OP is asking why they are RRR, rather than what the civilised world use, which is red to port on returning.
 
Lateral buoys and marks were originally uncoloured and distinguished by shape (of buoy or topmark). Then people had the idea of painting them ...

It is just a convention, like driving on the right/left, as has been mentioned, and like the driving convention the people who introduced it only thought about their local areas.

I note, without further comment, that in a number of spheres you will find there is an International System and a United States System.
 
Before IALA there was loads of unique and totally different systems. They managed to essentially get the whole world to use the same buoyage but offered individual countries the option of system A or B.

Seems daft i know but i expect at the time it was a sticking point and those that wanted to move things forward compromised by having 2 systems.

Red and Green were established as port and starboard some time before that.
 
I wonder if it arose because they have big rivers such as the Mississippi navigable to large vessels above the effect of tides so logically buoyed in the direction of the flow of the river whereas British rivers are generally only navigable to large seagoing vessels on the tideway?

What is the buoyage system on continental rivers like the Rhine & Danube?

EDIT: It seems the Rhine uses IALA A buoyage so obviously the Germans didn't use the above argument!

Why do they use 110 volts, why do they insist on imperial measurements, why do they spell colour incorrectly?

It drives me nuts.

Even my hand held VHF has US and international settings.

I'd forgotten about the US settings for the VHF. Same channels, with the frequencies changed just enough to remove half of any conversation with a VHF on international settings.


Another example is the International Meter rule. The Americans saw it, thought that's a good idea. So instead of joining it they created the Universal Rule.

The IALA system is nice, consistent, and logical, so that even without checking the chart you have a good idea what a given buoy means. Was the preceding British system equally logical, or not?

I ask because I happen to have a 1930s pilot book, and the approach instructions describe buoy shapes and colours that seem to be completely arbitrary and different for every port. If you didn't have a chart (or the pilot) it feels like you would have no idea whatsoever what the buoy was supposed to signify. Or is that just an impression given by the book (descriptions are briefer than a modern pilot and there are fewer plans) and a matching period chart would show there was some method to the madness after all?

Why are the buoys in this region (US) the reverse of our IALA A region?

It's not just the US - it's all of the Americas plus Japan, Korea and the Philippines. There were dozens of different systems until the first international conference to standardize buoyage in 1889. From that it was decided that port-hand buoys would be black and stbd-hand buoys would be red. With the advent of coloured lights for the buoys in the 1930s, most European nations started putting red lights on the black buoys to agree with the red lights that had been commonly used to light the port side of harbour entrances. The B regions decided it would cause less problems to keep the red buoys red and just change the black ones to green - it was region A that made the big swap changing red to green and black to red.

Japan, Korea and the Philippines were all effectively still under US control from after the Second World War and the Korean war at the time the IALA system was brought into being. That is why they use the USA's system. A lot of the Caribbean also uses the IALA B system because of it's proximity to the US.
 
*This story may not be completely true*

The Island of Saint Martin in the Caribbean is divided between two nations, Sint Maarten (part of the Netherland Antilles) to the south and, to the north Saint Martin (an Overseas Collectivity of France and part of the European Union). The Netherland Antilles follow IALA B, France adheres to IALA A.

On the eastern side of the island is the marina of Oyster Pond, the entrance channel to which is bisected by the international boundary. It therefore follows that when entering Oyster Pond the port side of the channel should be marked by green (IALA B) buoys and the starboard side by green (IALA A) ones.

I think in practice pragmatism has prevailed and the French islands follow IALA B, as does the British Overseas Territory of Anguilla.

IALA B came into being in 1980. If the US had that much control over Japan, then why weren't they made to drive on the right side of the road?

According to these people, both sides of the island follow IALA B: http://www.islandandresort.com/mari...s-235/190-st-martin-sint-maarten-marinas.html

AFAIK, all of the Caribbean, and all North, South and Central American countries follow IALA B.
