Unit 2 MKIV
MKIV furling systems are strong, lightweight and aerodynamic, with the performance and features Harken® is known for. Longevity, ease of use, and simplicity of installation are crucial components of the design. These free-rolling furlers make all the difference in headsail control by allowing racers and cruisers to quickly furl and reef from the safety of the cockpit, while maintaining great sail shape and optimal speed.
Head and tack swivels feature Torlon® ball bearings and operate independently to improve the shape of a partially furled sail for added power through the water. Non-corrosive hardcoat-anodized swivels require no lubrication.
Aluminum line guard, torque tube, and swivels are deep-
saturation hardcoat-anodized for no-fade UV-stabilization, strength, and durability. The hardcoat-anodized line guard
is urethane-coated for additional corrosion protection.
Aerodynamic aluminum Air Foils® handle extreme reefing loads. Double foil grooves allow fast hoists, douses, and sail changes.
Units are adaptable to a variety of rigging options for easy installation. Harken toggle assembly accepts standard turnbuckle using swage, rod, Norseman®, or Sta-Lok® terminals. Toggle flips for fork or tang chainplate installation. A single stainless steel clevis pin provides access to the turnbuckle for adjustment.
Specially formulated low-stretch black line is abrasion- and UV-resistant; standard on units 0, 1, and 2.
