Harken Small Boat furling systems allow the trailerable cruising or dinghy sailor to set and furl the jib from the cockpit. Swivels are independent of the headstay, allowing you to tension the luff separately from the mast rake. An optional halyard swivel can be installed on your headstay so you can raise or lower the sail without removing the headstay. This system includes 208 drum and 207 upper swivel. Halyard swivel not included. Harken Small Boat units are for furling only, not reefing.
