the IALA system of buoyage was introduced internationally.
The USA did not sign up to this so all your channel buoys are opposite

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:

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.
