Designed for cruising yachts between 8.3 and 11 meters (27–36 feet), the Harken Unit 1 MKIV Ocean Jib Furling System delivers effortless headsail control with race-proven engineering adapted for everyday sailors. Whether you're coastal cruising or venturing offshore, this system allows you to furl and reef from the safety of the cockpit—without compromising sail shape or performance.

Constructed from hardcoat-anodized aluminum and UV-stabilized for long-term durability, the MKIV Ocean features multiple rows of Torlon® ball bearings that eliminate friction and require no lubrication. The single-groove foil accommodates a 5 mm luff tape, making sail changes fast and straightforward. With modular extrusions and a robust halyard swivel, the system ensures consistent furling and reefing even under load.

The Unit 1 system supports wire diameters up to 8 mm and rod sizes up to -8, with clevis pins sized for standard rigging hardware. It’s engineered to handle headstay lengths up to 16.12 meters (52'11") and includes everything needed for installation: foil sections, connectors, bushings, sail feeder, upper foil cap, lower drum, halyard swivel, Loctite, Allen keys, and reefing line.
