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 and 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.
