The more I read, the more questions I have...Can anyone give me some definitive rigging measurements of where to attach the main halyard on the upper boom? Between sail rings 9 and 10 is what I've deducted from reading; assuming 9 for lighter winds, 10 for stronger. I'm just looking for a few nice rigging options to play with for a recreational sailor. (Kind of like the gooseneck adjustment options.) Thanks, everyone.
