Not sure. Never sailed in light air with Melges 24's but I know that it is not uncommon for them to beat a N20 around the bouys in that kind of stuff. I would say that you would probably want to try to really play the downwind angle alot , heading up when it feels to be decelerating and down when you have some speed. Just make sure you've got boards mostly up (windward board all the way up), downhaul off, keep your weight forward, trim the jim and make sure the chute stays full. That is assuming everything else on the boat is well setup (mast rake, diamond tension, ect..)
