The furling element also includes one and preferably two grooved luff foils which are formed in and extend along the length of the plastic member. Split bearing elements are 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 integral fasteners for fastening the two segments together along their length. 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.
