Thank, Jake. FWIW, mine's a 1995 w/ rake-able spreaders, and my new rags'll be cut for pre-bent mast. I just didn't know what benefit they convey if one's sail isn't apropriate for true prebend aproach.

You're saying that if you use the "loose diamonds" aproach, but rake 'em aft, the axis of bend is shifted from directly across the minor axis to a line somehwhere between minor and major, so the mast presents a better airfoil to the wind?



Got it.
