Also, I found a great primer for racing basics. And I knew it was for me by this line in the intro:
Every race, you'll make many mistakes. The key is to forget about them for the moment, and go on with the race. It never helps your game to dwell on a mistake. All the energy spent on the last blunder takes concentration-concentration that is needed for sailing a great race. It might help to say "f**k," but only once.
