Jeff,
Thanks for the ideas! We were at your recommended settings, and honestly had good speed for most of the day. We're at slightly below the top hole on the rudder retainer in light air. We didn't rake back in Hyannis and it showed.
I think Newport it was just a long day and we started loosing concentration. That is our biggest frustration honestly with the boat. It takes Jessica about 90% focus 100% of the time to keep the boat driving fast upwind. When I have helmed I found the same thing. It is most notable in light air, 3-5kts. Once I'm in the wire consistently the groove is wider. Do the newer sails help alleviate the strain on the helmsman?
