ABSTRACT:
A plastic roller furling apparatus includes an elongated member or furling element and a pair of longitudinally extending parallel wires encased therein. The wires of twisted stainless steel are extruded or molded into the member. The member also defines a central opening or passageway which extends therethrough. This passageway is dimensioned or sized to fit loosely around a stay in which the apparatus is installed. The furling element also includes one and preferably two grooved luff foils which are formed in and extended along the length of the plastic member. Split bearing means are also provided at or near the base of the plastic member and a furling drum or jib sail spool is provided for rotating the plastic member about a stay to furl the sail. The plastic member also includes first and second longitudinally extending segments which extend along the length of and divide the plastic member into two pieces. The segments each include fastening means integral thereof for fastening the two segments together along their length. When fastened together the two segments define a central opening for fitting around the headstay of the sailboat. A split body member is also provided and clamps around the elongated plastic member. This split body member may include a first bearing element for engagement with a split bearing which is installed over the stay.
