ABSTRACT:
A batten end fitting includes a coupling having slots therein for securely receiving slides mounted for movement in a mast track formed longitudinally in a mast and rollers rotatably mounted thereon for movement along the mast in response to movement of the slides. A socket or pivot is formed in the coupling, and a ball is defined on the forward end of a batten holder for rotatable engagement with the socket when the batten holder is flexibly secured to the coupling. The batten holder includes a pair of plates for receiving therebetween a luff end of a mainsail, and a positioner is slidably mounted between the plates for receiving a forward end of a batten sewn into a pocket in the mainsail. The positioner selectively positions the batten relative to the plates and thereby selectively tensions the batten within the batten pocket. The ball on the batten holder being rotatable in the coupling socket allows the batten to rotate relative to the coupling to eliminate torque friction between the slides and the mast. The rollers on the coupling absorb forward thrust of the batten in the direction of the mast to eliminate pressure friction between the slide and the mast.
