MKIV furling systems are strong, lightweight and aerodynamic, with the performance and features Harken® is known for. Longevity, ease of use, and simplicity of installation are crucial components of the design.

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. Independent halyard and tack swivels furl sail center before head and tack for improved sail shape when reefed, whilst being lightweight, an advantage when hoisted as it reduces pitching and heeling. Stainless steel feeder allows fast singlehanded hoist and sail changes, with the precision-extruded, double-groove foils for smooth sail handling.

To complete this set a toggle assembly is required.
