When I would try to furl-in my mainsail on my SO36i the lower one foot of the mainsail would catch on the edge of the mast. I told the dealer about this problem and last Thursday the technician really tightened up the mainsail halyard. It was easier to furl in the main after sailing on Saturday. I feel that the halyard is way too tight and leaves a (wavy) wrinkle in the leech all the way up the mast.
On the other hand, I have furled-in the main with on tension on the out-haul. The rolled sail takes up too much space in the mast and causes it to jam in the mast.
