Thanks Howard. My boat is an 83. And yes I think you answered my question. Not sure what the s/s guide is. pretty sure I dont have one. No there is no damage to the luff track anywhere. I think it may be a factor of my main just not fitting together right because of a bad repair on the sail. Is anyone sailing a hobie 16 in Ft lauderdale this weekend? maybe I could come look at your setup before you head out.
