FOR RACING AND CRUISING SAILORS

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 optional speed.

Easy Reefing and Furling

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.

More Furling Power

large inner spool diameter increases mechanical advantage for powerful reefing and furling.  Smaller outside dimension allows unit to fit narrow bows or below deck.  Unit rotates around rod or wire headstay so furling bearings do not carry the headstay load for easy furling.

Long-lasting Protective Finish

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.  Specially formulated low-stretch black line is abrasion-and UV-resistant; standard on units 0, 1, 2.

Easy Maintenance

Harken MKIV furling systems are one of the few systems on the market that can be easily serviced. The ball bearing assembly can be taken apart, cleaned, and new ball bearings installed, which dramatically extends the useful life of the furler.

*NOTE:* The determining factor for unit size is the wire/rod diameter of your headstay; boat length suggestions are just guidelines. Toggle assemblies not included & must be purchased separately.
