Re: Sailing yesterday - lessons learned?
Flagging at the leech may not be an issue. If the sail is near the end of it's life then it just indicates that you have a tired sail, not a trim problem. There is probably a leech line that can be used to control it, but be careful not to over tighten it and artificially tighten the leech.
Do you have sail tells? The most important thing to watch are the two lower tells on the genoa. If they were both flying backwards then the sail trim was okay. Your main sail probably has tells on the leech (one at each batten), and those should be flying backwards. If they are flying to windward then you are over trimmed.
If you have a more experienced person that can go out with you they can give you some feedback on your sails. It's possible that either the sails are fine and trim would fix the leech issue, or that they are quite worn. I know that sails which looked good to me when I bought my first boat clearly look pretty shot to me now that I see them through more experienced eyes. It's amazing how much higher boats will point with good sails. Good sails don't need to be expensive either, the new owner of the Catalina 25 that I sail on got a great (hank-on) lightly used genoa for under $200 that is letting us point at least 5 degrees higher than we could with the old one.
Note that bringing in the mainsail as far as it will go will result in excessive weatherhelm on most boats. Bringing the boom all the way into the centerline may not work very well. Use the old phrase "when in doubt, let it out" and let the main out until it luffs (the front foot is flagging), then bring it in slightly to trim.
Good luck and enjoy the new boat!
