ccriders Maybe I wasn't clear enough in my explanation, but look at it this way; You have a triangle consisting of a straight vertical side (the mast) with a fixed length, a Hypotenuse (Headstay, Mainstay, Jibstay, luff of Jib) with a fixed length; therefore if I lengthen the horizontal length by moving my tack forward, my angle of the mast to deck (vert. to horiz.) decreases and the top of my mast therefore will move slightly forward, no matter what my pre-bend is or will be. Do understand that this procedure is only possible if you slacken/loosen you backstay.
Tropicat nailed on the "mast".
My "fix" to reduce the weatherhelm I encountered by over a 100% cost me niltch, I'm still sailing with my old sails running a good 6.5 knts in 15 mph wind at 40 degree to the wind without wetting the rail.
I'm happy. The next owner can buy new sails that are "flat", install an hydraulic Boom-Vang and install 1 to 6 ratio out-haul and Cunningham.
