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.
Multiple rows of large-diameter Torlon® ball bearings used in high-load areas to minimize friction for easy reefing and
furling; require no lubrication or isolating seals. The large inner spool diameter increases mechanical advantage for powerful
reefing and furling. While smaller outside dimension allows unit to fit narrow bows or belowdeck. Unit rotates around rod or wire
headstay so furling bearings do not carry the headstay load for easy furling. The Aluminum line guard, torque tube, and swivels
are deepsaturation hardcoat-anodized for no-fade UV-stabilization, strength, and durability. The hardcoat-anodized line guard
is urethane-coated for additional corrosion protection. Specially formulated low-stretch black line is abrasionand UV-resistant;
standard on units 0, 1, and 2.
