Engineered for cruising yachts between 6.5 to 9.1 meters (21–30 feet), the Harken Unit 0 MKIV Ocean Jib Furling System delivers precision, reliability, and ease of use in a compact, lightweight design. Whether you're coastal cruising or pushing offshore, this system transforms headsail handling into a smooth, one-person operation.

Crafted from hardcoat-anodized aluminum and fitted with high-load Torlon® ball bearings, the MKIV ensures low-friction furling and reefing without the need for lubrication. Its single-groove foil accommodates a 5 mm luff tape, making sail changes straightforward and efficient. The system includes modular extrusions for easy customization and a robust halyard swivel that maintains consistent sail shape while furling.

With a total weight of just 5.9 kg (13 lbs), it minimizes weight aloft—enhancing boat balance and performance. The MKIV’s clean design and rugged construction make it a trusted companion for sailors who demand control, safety, and durability in every tack.
