Abstract
An assembly for feeding the luff of a jibsail into a grooved foil mounted on the headstay of a sailboat comprises a grooved feeder and prefeeder adapted to be removably mounted on the headstay. The feeder comprises a pair of interfitting spline members adapted to be assembled together by relative sliding movement along paired guideways to freely encircle the headstay and to confine the lower end of the foil therebetween and to be clamped to the latter and to each other as a unitary element by a single attachment means, such that the grooves of the feeder and foil are rigidly maintained in alignment. The prefeeder comprises a guide slidably and universally pivotal on the headstay at a location below the feeder and having a luff receiving opening through which the luff of the sail may be fed and guided to the grooved feeder and thence to the grooved foil. A pair of tubular spacers are removably secured to the headstay for sliding longitudinally thereon at locations above and below the prefeeder respectively for spacing the latter from the foil and for spacing the prefeeder from the lower attachment of the headstay with the boat, thereby also to provide means for supporting the foil w…
