My aftermarket rotator points *forward* from the mast.
That's okay, it lets me make my rotator self-tending, self tacking. See, there's a little tab sewn onto my tramp, just about dead center, a little forward of that maybe. The tab has a 1" grommet in it, and is secured to the tramp with another, making it quite strong.
So you take a lengh of bungie, pass it once through the grommet in the tab, take both ends and attach them to the rotator, sticking them into the jamcleats, with one end of the bungie going on each side of the mast.
With no tension on the bungie, nothing happens. But tighten up a little, and suddenly, the mast wants to be rotated - either way, doesn't matter. So when under way and the mast is slightly underrotated, I just snug up that bungie and the mast rotates to wherever I care to set it. When I tack, it just flips over to the other side, allready set. Works to windward, downwind, reaching, you name it - one little tweak and you're done until you change point of sail.
*Why* it works will become obvious when you try it - - or if you just have to know first, post a reply and I'll bore you with the details.
