Independent halyard and tack swivels furl sail center before head and tack for improved sail shape when reefed. Precision-extruded, double-groove Air foils for smooth sail handling and fast sail changes. Specially formulated low-stretch black line is abrasion and UV-resistant; standard on units 0, 1, 2.
