Bill,We are having a new jib made and would like some advice on what can be done to make this new sail a roller reefing and furling jib.As I understand the problem, the concern about reefing on a roller is the additional sail material (required to give the sail draft)in the center of the sail. When reefing the jib on a roller, this additional material does not roll up the same as the top and bottom of the sail. The resulting shape is poor which not only impacts sailing ability but could possibly damage the sail.My research to date has disclosed two possible ways to overcome this problem. The first is to add some line (maybe 3/4" dia) in the middle 50-60% of the luff, just aft of the bolt rope. The purpose of this is to cause more of the center part of the sail to furl with each turn of the roller. The second way is to add foam to the luff, which I believe (although I am not sure)facilitates a more uniform rolling of the sail around the headstay. The negative of these two proposals is shape at the luff. While I do not race, I try to maximize performance.While there are other concerns present in reefing a jib (length of the genny track, reefing patches, etc), my question relates to the benefits obtained from the line in the luff or the foam luff. Do these techniques actually work? I guess another question is "Is roller reefing a jib, maintaining sail shape and not damaging the sail feasible."Steve Carpman
