Yep I'm racing Portmouth. It's inland lake sailing, against three of the top 5 Catalina 22 Gold Fleet National Champion group, and most weekends are under 15. Failing to go means staying home and cutting the lawn and other like onerous tasks, so I go and try to compete. How critical is jib car setting? Will adjusting it actually improve speed, or is it just a put it in the middle of the track and ignore kind of thing?
