Harken Screecher, Staysail & Gennaker Furlers

Harken Screecher, Staysail & Gennaker Furlers

Spinnaker Staysail
Furled staysails are easy to hoist rolled and can be deployed or doused from the cockpit. In marginal conditions the sail can be struck instantly without changing the trim of the boat. Multiple stacked races of Torlon® ball bearings ensure smooth operation under load. Systems include a lower drum with snap shackle, fairlead and Cam-Matic® cleats, and an upper swivel with provision for halyard attachment.

Gennaker® Furling
Gennaker®® furling was developed for large single-handed boats and huge oceangoing multihulls. The 1900 Gennaker® furler is ideal for drifters and reachers on multihulls to 45 ft (14 m). Smaller boats use the 3049. The drum unit features a fairlead, while the upper swivel is designed for direct halyard attachment. Custom designs are available for larger boats.

Screecher Furling
Use screecher furling systems on multihulls to 32 ft (9.60 m) and easily driven sport boats. Perfect for jib reaching, screechers are set on the bowsprit. They are often carried upwind in light to moderate conditions and used as storm spinnakers when it’s blowing.

Systems are sized to handle loads of 2:1 halyards and multiple stacked races of Torlon® ball bearings ensure smooth rotation under load. Fairleads allow the furling line to lead aft to the cockpit.
