PRODUCT DESCRIPTION
MKIV Ocean furling systems for cruisers are engineered for strength, longevity, and ease of use. These free-rolling furlers make all the difference in headsail control by allowing cruisers to furl and reef from the safety of the cockpit, while maintaining great sail shape. MKIV Ocean furling systems offer the same quality as MKIV for racers but without features cruisers don’t need.
Made of hardcoat-anodized aluminum and UV-stabilized for durability, MKIV Ocean furlers include multiple rows of Torlon® ball bearings to minimize friction and make pulling the furling line a less physical experience. The bearings require no lubrication for easy maintenance. The extrusion features a single groove foil.
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.
**Furling line IS included with this furler model.
