MKIV Ocean Furling

MKIV Ocean Furling

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. They are made of hardcoat-anodized aluminum, UV-stabilized for durability and 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 and feature a single groove foil.

Line guard top is composite, not metal. We don’t do this to take cost out. We do this because it’s just plain tougher. No dents.
