Harken Small Boat furling systems allow the dinghy or trailerable cruising sailor to set and furl the jib from the cockpit.

Harken has developed an enviable reputation for quality. That reputation is certainly furthered by these small boat furling systems. All feature their famous ball bearing design. Furling and unfurling is relatively effortless. And the units are quite durable.

Note that these systems require a wire in the leading edge of the sail and that they are designed to provide furling (rolling the sail all the way up) rather than reefing (rolling it just part way).

This unit is for use on dinghies to 20' (6.1 m); catamarans to 18' (5.5 m)
