Abstract: Sailboat luff system including a longitudinal one-piece extruded luff member, a feeder secured about the luff member, a spacer, and a prefeeder all positioned from top to bottom along a forestay or a headstay of a sailboat. The longitudinal extruded luff member includes two channels or grooves encompassing a third channel or groove, the two channels wrapping around to form the third channel where the third channel is supported by the forestay or the headstay of the sailboat. The extruded luff member is of a material to maintain memory of the channels with respect to each other and snaps around the forestay or headstay with a flick of the fingers. The feeder includes slots leading to the tapered holes or grooves, beveled edges and a headstay groove for securing the feeder about the luff member and feeds the sail tape through slots and grooves, respectively, towards the extruded luff member.
