I had a great sail a couple of days ago. Pretty sure that's the fastest I've had her yet. I didn't have my gps with me so the world will never know but it was faster than normal for me (I was solo). Anyways, while speeding along I got a harsh/loud vibration and oscillation in my rudders. Is there anything wrong with this? I feel like it's got to be stressing something is shouldn't be stressing and generally slowing me down. Maybe there is something that needs tightening or shimming? -Jaseun
