Engineered for serious offshore cruisers and performance sailors, the Harken Unit 3 MKIV Ocean Jib Furling System delivers robust reliability and smooth furling for yachts in the 45–60 ft (13.7–18.3 m) range. Designed to withstand the rigours of bluewater sailing, this system combines precision engineering with corrosion-resistant materials to ensure long-term durability and ease of use.

Key features include:

  • Single-groove foil extrusion for streamlined sail changes and reduced weight aloft.
  • Torlon® ball bearings in both the halyard swivel and drum, offering low-friction furling without the need for lubrication.
  • Hardcoat-anodized aluminum construction with UV-stabilized components to resist the harsh marine environment.
  • Generous sail capacity and reefing control, ideal for handling large headsails in heavy conditions.
  • Modular foil sections for easy installation and maintenance, with a sail feeder included for hassle-free hoisting.

Whether you're cruising the coast or crossing oceans, Unit 3 offers the strength, simplicity, and performance needed to keep your headsail under control in all conditions.

The MKIV Unit 3 Ocean Furling System comes without a Toggle. Purchase the base toggle separately.
