Neat stuff.

Just as Americans and Canadians speak two slightly different but
mutually understood versions of a common language, the minor
differences in our navigational aids need not present any
insurmountable obstacle. In Canada it's still "red right returning".
Horizontal lines mean danger, vertical lines imply safe passage, and
keeping the top of the chart, bottom of the chart, sunrise and sunset
in mind will help unlubberize those black and yellow cardinal buoys.

Leave it to an "international" group to scew up a buoy system.
