Systems require a drum and upper swivel. Some are also available as a complete kit. See page 163 for details. Small Boat units are for furling only, not reefing. Upper Halyard Swivels Harken’s high-performance 207HP swivel has needle roller thrust bearings that function smooth- ly under very high loads required at the top end of sportboat fleets, while matching the dimen- sions of our other 207 units—making an upgrade easy. Standard upper halyard swivels feature multiple stacked races of ball bearings for low friction rotation under load. Delrin® ball bearings are used for low-load swivels. Torlon® bear- ings are used in standard and high-load swivels. Shackle or forked tang attachment options are available. Hoistable Halyard Swivels An optional hoistable ball bearing halyard swivel can be installed on the headstay so the sail can be raised or lowered without removing the headstay. Swivels are independent of the head- stay, which allows the luff to be tensioned separately from the mast rake. Hoistable swivels work along with any standard Harken Small Boat furler.
