I sail in different classes with different competitors with different styles, so I don't get so surprised and can concentrate on sailing. Those with less experience, even though they go fast, lose on the corners because they don't have as good boat handling skills. Bad boat handling wipes out the best tuning, the smoothest hull. If you don't handle the boat well, you look slow even though you're not. That's why you have to practice, that's why practice is not a race.
Practice is practice.
I try not to get distracted and try to keep focused on boat speed. I know exactly where I can cross on port tack. I have to concentrate a lot more on other boats. We love them if we're coming from behind because we can make out like bandits. Best response is steer up quickly and throw them off guard.
