your green river bouy may be a bit more challanging if the river is
open at both ends or if it is so long that you don't know which way is
returning. keep in mind that the bouy numbers go up when returning.
One of the best things to do is to get charts and see what the red and
green bouys are keeping you away from. then you begin to understand
what they mean
hope this helps

In Europe the direction of bouyage is the same direction as the flood tide,
and when entering a harbour or river mouth the bouyage is red-to-red and
green-to-green. Time the shipping world got together on this and agreed a
worldwide system.


But IALA A and IALA B are the result of the world getting together and
agreeing!

I undertand that IALA B, now used only by the US, its territories, and
its client states in Asia, was the original proposal. But the
Europeans were slow to understand the import of a unified marker
system. So they failed to support it. And then came IALA A and the
current mess.
