Harken Unit 3 Reflex

The Harken Reflex furling system is a game changer! The previous generation of free-flying sail furlers often resulted in partial or uneven furling. Patented Harken Reflex furlers provide sailors confidence that their free-flying spinnakers, gennakers, and code sails 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. Unit 3 is rated at 4.5T MWL for boats up to 17.4 m (58').

Unit 3 furlers use a Dyneema® core, which twists less and handles increased halyard loads without stretching, making them well suited for code zero applications by eliminating need for additional luff cable. Smooth polymer cable jacket protects sails against abrasion.

Compact design reduces weight aloft, maximizes luff length. Padded cover prevents damage to spars.

Offset holes in drive sheave grip rope securely when furling.

Quick-release modular T-fitting allows single drive unit to handle multiple sails. Rolled sail easily disconnects with the pull of one spring-loaded pin; new furled sail slides and locks into T-slot.

Flexible polycarbonate alloy cowling allows rope to be easily fed into drive sheave without tools; keeps rope captive. Stripper and feeder work together to prevent furling line from jamming.
