Harken MKIV Ocean Furling Systems
Harken MKIV Ocean furling systems are designed specifically for cruising sailors who value strength, longevity, and ease of use. These free-rolling furlers allow headsails to be furled and reefed from the safety of the cockpit while maintaining excellent sail shape—making sail handling simpler and less physically demanding.
The MKIV Ocean line is built by Harken using the same quality standards as the original MKIV furlers, but with a simplified feature set focused on the needs of cruisers. You get Harken reliability and performance without paying for race-oriented features you may not need.

Construction & Performance
MKIV Ocean furlers are constructed from hardcoat-anodized aluminum and UV-stabilized materials for long-term durability in harsh marine environments. Multiple rows of Torlon® ball bearings minimize friction, making furling smoother and significantly reducing the effort required on the furling line.
- No lubrication required
- Smooth, free-rolling operation
- Single-groove foil extrusion
Easy Maintenance & Long Service Life
Harken MKIV furling systems are among the few on the market that can be fully serviced. The ball bearing assembly can be disassembled, cleaned, and refitted with new bearings, dramatically extending the usable life of the furler and reducing long-term ownership costs.
