P.J. O'Rourke made the quip that "port wine is red, and so is your face if you get port and starboard mixed up." Which doesn't help, but it's funny.

For sailors, we learn "red-right-returning," which means to keep the red aids to navigation on the right (starboard) side when returning to port. Which is great, except when it doesn't apply--parts of Europe, Australia, a lot of Asia.

You'd think this would be a solved problem by now, but nope.
