The Harken Reflex furling system is a game changer!

The previous generation of free-flying sail furlers often resulted in partial or uneven furling.

Patent-pending Harken Reflex furlers provide sailors confidence that their free-flying spinnakers and gennakers will furl with speed and control.

The result?

  • Sailors use downwind sails more often—even when sailing shorthanded.
  • The compact drive unit is easier to handle than other designs.
  • Pull the furling line and the drive unit reacts reflexively to rotate the torsion cable, immediately transferring torque to the head swivel without unwanted corkscrewing delaying the response.
  • The head swivel reacts instantly, spinning the sail smoothly and completely from top to bottom for an even roll-up and super-tight wrap.
  • The furled spinnaker lowers easily to the deck, ready for the next hoist.
  • The Reflex cable is more torsionally resistant to corkscrewing than the current breed of textile cable.
  • Braided stainless steel wire filaments over braided polyester core transmit torque to head swivel through both tension and compression for faster furling (textile cable transmits through tension only).
  • The quick-release modular T-fitting allows a single drive unit to handle multiple sails.
