Harken Unit 00AL Jib Reefing & Furling 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. *Clevis pin assembly required - sold separately, **Optional Part Consult with Harken if boat length exceeds specifications above.
