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 280 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. Series 280 furlers and accessories feature a “fast pin” feature for rapid connection and disconnection of furling components. Attachment options include HR shackle, 3:1 fairlead and torsion rope thimble. The Ronstan Series 280 system is rated to 16,000kg NBL and is optimised for use with 12mm furling line (not included). The set includes: standard furler RS228000, top-down adapter RS228060, top swivel RS228010. 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.
