Yeah.. it's easy - just give way to anyone bigger, faster, more coordinated, or better looking than you. And watch out for the event threshold close to the bar in a river, or just out the back because the rules change.
Unless you're a kiter, in which case you don't give way to anyone.. ever. Which is not relevant, because kiters shouldn't be in waves anyway, because they suck at wave riding..
Most of the debate on that thread was over whether starboard was really starboard, or if it could be port at the same time.. which in the end all boiled down to Einstein's theory of relativity, and whether you were talking about the sailor or the sailing location.
Sheesh... some people are slow learners!
