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. These free-rolling furlers make all the difference in headsail control by allowing racers
and cruisers to quickly furl and reef from the safety of the cockpit, while maintaining great sail shape and optimal speed.
Halyard Swivel Turns Freely Strong, lightweight halyard swivel reduces windage and weight aloft to minimize pitching and heeling. Stacked bearing races evenly
distribute radial and thrust loads to ball bearings; foils turn freely under halyard loads. Independent halyard and tack swivels furl sail center before head and tack for improved sail shape and upwind pointing.
