174 163 165 208 483 1134 434 435 436 Small Boat Furling Components: Drums All Harken Small Boat furling components can be purchased individually to mix and match. Systems require a drum and upper swivel. See page 162 for swivels. Some systems also available as a complete kit (see below). Conventional Furling Drums Harken Small Boat furling systems allow the trailerable cruising or dinghy sailor to set and furl the jib from the cockpit. Drums feature multiple stacked races of Delrin® or Torlon® bearings for smooth rotation under load. Small Boat units are for furling only, not reefing. Continuous Line-Drive Furling Drum The continuous line-drive furler is the perfect solution for high-performance skiffs and dinghies that use oversized jibs/gennakers and for staysails on larger boats. Unlike conventional furling drums, the low-profile line-driver never runs out of line, and can completely furl any sized sail. Offset holes in the drive sheave grip line securely, with the stripper arm and feeder working together to prevent line from jamming. The line guard adjusts in 90-degree increments to accommodate attachments to the boat. Delrin is a registered trademark of E. I. du Pont de Nemours and Company or its affiliates. Torlon is a registered trademark of Solvay Advanced Polymers L.L.C. Continuous line-drive furler features offset holes in the drive sheave to grip line securely.
