I was wondering why racers have their sails almost to the deck level? Is it just to reduce the heeling force, or is there something else going on? And if it is just to reduce heeling, then in light wind it would seem you could attach the halyard lower on the spar (thus raising the sail higher for visibility). I would also think that you can change the center of effort of the sail by both moving the halyard location and the gooseneck. (together). If you only move one or the other, then the lower spar will now be at an angle (don't know if it matters). True? Finally, is reducing/eliminating weather helm the goal for gooseneck adjustments? Or is there another goal in mind? thanks!
