Harken's 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.
An optional hoistable ball bearing halyard swivel can be installed on your headstay so you can raise or lower the sail without removing the headstay.
The 3mm continuous line furling drum is for use with swivel 164.
