Well i have had the same problem and what yu can try is tip the boat over and get some one to hold the sail straight and pull from the top to find the problem it helps by increasing the chance of being able to see. Lube the sail edge and the track, the batterns dont do to much but might help. Make sure your head to wind and last you might want to try using 2 peices of rope. 1 about 3mm thick conected to the main halid and connect that to a thicker peice (like th jib sheet) and pull like hell and well if all of these dont work, well you have one stubbern sail. Well have fun and sail it as offen as possible. Bye
