For cruising sailors, MKIV Ocean furling systems offer reliable sail control like MKIV for racers but with features specifically configured for the way they sail – and at the right price. They are made of hardcoat-anodized aluminum, UV-stabilized for durability and includes 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 are designed for easy installation.
