7 races are way too much. A normal race takes around 45-60 minutes and with general recalls, resetting of the course and waiting for all the boats to finish means at least 1.5 hour between each start. That means a very long day on the water, no fun! I prefer two races, lunch break at the beach, and then two more races. This gives you a SOCIAL LIFE at the regatta and that's important.
