More on the "new tack"

In my previous post I outlined the "new tack", a simple one-piece-at-a-time approach to shunting the rig.  This has in its favor simplicity and few moving parts.  At least in a smaller sized vessel, I wouldn't mind moving the yard from one bow to the other by hand.  I can handle just a yard and sail as long as the mast isn't flopping around as well!  (As can happen shunting in a choppy sea state.)

However, one might want to control the movement of the sail also with a "tack track" or "tack line" of sorts.  Reference the sub topic Shunting Solutions in Michael Schacht's excellent article Proa Rig Options: Crab Claw

In case any of you are not familiar with Michael's body of work, his site ProaFile, is the motherlode of proa and other such research on the web.  A link here and more kudos later:
