Now, Harken introduces MKIV Ocean offering MKIV quality, specifically configured for the cruising sailor. It is engineered with strength, longevity, ease of use, at the right price without extra features cruisers might not need.For occasional racers, the MKIV line is engineered with ease, durability, and winning in mind. The split drum can be removed easily for use with racing sails, providing the longest possible luff length. The independent swivel supports optimal sail shape.Low-friction efficiency for easy furling and reefingMultiple rows of Torlon ball bearings in high-load areas minimize friction. Stacked bearing races evenly distribute radial and thrust loads; drum and halyard swivel turn freely under load. F oils rotate around headstay so headstay load is isolated from the furling unit for easy furling. Large inner spool diameter increases mechanical advantage for powerful reefing and furling.Stands up to sun, salt, and timeAluminum line guard, torque tube, and swivels deep-saturation hardcoat-anodized, UV-stabilized for durability. Line guard polyurethane-coated for wear protection.Foil joints Specially formulated low-stretch black line is abrasion and UV-resistant; standard on units 0, 1, 2. Aerodynamic (MKIV) and round (MKIV Ocean), MKIV foils handle extreme reefing loads. Triple-interlock foil joints withstand years of torque loading: foil connectors geometric shape interlocks with foil; secures with syringe-injected adhesive; screws provide final lock.
