Unit 00AL is the perfect jib reefing and furling system for small cruising boats under 26 ft (8 m). It combines most of the features of larger Harken� furling systems in a simpler unit. Like other Harken� systems, the main components of the 00AL are 6061-T6 Hardkote-anodized aluminum with Teflon� impregnation. Features include a free-spinning, omnidirectional bearing system with multiple ball bearing races, a double grooved foil for racing sail changes, and a lightweight halyard swivel to minimize windage and weight aloft. The furler�s large inside spool provides plenty of mechanical advantage for smooth, easy reefing and furling. There are enough aluminum foil sections to build a headstay with a pin-to-pin measurement to 31 ft 6 in (9.60 m). Harken� offers an additional foil and connector to extend headstay length to 35 ft (10.7 m). Note: You must cut your headstay to install 00AL furling. You must also purchase a Harken� clevis pin to match your chainplate.
