i know there's a lot that goes into rigging a sail properly. i'm having difficulty finding out the effect certain things have on how the sail holds or spills the wind ( like how more or less outhaul changes the sails performance, or downhaul.)
how high should the boom be? - i've read that higher is better because it allows you to put more weight on the mast foot, but where is a good start?

i know this is a pretty huge question, but if someone could point me into the direction of any articles, id really appreciate it. thanks
