If you have not decided on a format for your race, you might want to try a distance race. This is easier for the RC to run and more fun/less intimidating for first time racers. A "poker run" is one format to try: boats race to five spots and pick up a playing card, the boat with the best poker hand at the end wins a prize.

If you are running a bouys race, recommend you get the RC and mark boats out the day or weekend before and run some practice races. It is also an opportunity for boats to practice starts, etc.
