Ronstan's range of continuous line furling systems puts great performance and reliability within the reach of cruising and racing sailors alike. The Ronstan Series 120 top-down furling system is designed for downwind sailing with soft luff sails in true wind angles greater than 90˚. Top-down furling provides a new level of simplicity, safety and speed for handling of asymmetric spinnakers and gennakers. Cruisers can now store, deploy and retrieve these sails as simply as they would a furling headsail from the safety and convenience of the cockpit. Racers too can benefit from the characteristics of top-down to allow superfast retrieval of code zeros by pre-winding the torsion rope and firing the sheet when ready. Drum diameter is matched to load rating to provide the optimum balance between speed and ease of furling. Advanced drum technology: Drums incorporate a sophisticated furling line groove profile and cross-hole geometry to grip the furling line securely when furling. When deploying the sail the continuous furling line self-ejects from the grip zone, remaining stationary for smoother, safer operation with minimum rope wear. A PTFE perimeter strip ensures the unloaded furling line can't fall from the drum or become snagged. Furlers and top swivels feature a factory sealed, maintenance free bearing. The continuous furling line is easily fitted and removed from the furler without tools, so it can be left on deck when the sail and furler are stowed below. The furling line guide can be adjusted to suit either 0 or 90 degree attachment as required. Both the furling drum and top swivel have retained clevis pins and the drum includes high resistance shackle RS212050 on its underside. Attachment options include snap shackle, 2:1 fairlead and torsion rope thimble. A compact rotation stop can be installed on the underside of the Series 120 furler to prevent inadvertent unfurling of the sail; locked out when in use and in when the sail is furled or stowed. The Ronstan Series 120 system is rated to 3,600kg NBL and is optimised for use with 8mm furling line (not included). The set includes: top-down furler RS212100, top swivel RS212010. Ronstan continuous line furling systems require the sail to be either completely unfurled or completely furled – the furler cannot be used with a partially furled sail.
