I've been able to achieve my target polars consistently when on port tack but once I flip over I stall out about 15 - 20 degrees below where my target wind angle should be. If I poke up once I get within 10 degrees of where I should be I'm about 40% of the boat speed I should be hitting at that angle. I suspect my mast is not straight and that it could be favoring to the starboard side of the boat. But before I start to redo the rigging I wanted to get some thoughts.
