RONSTAN Top-Down Furlers - Overview
Ronstan's Top-Down Furling system for Downwind Sails - Furling of "soft luff" downwind sails such as asymmetric spinnakers and gennakers is possible utilising a Top-Down adapter with the standard Furler & Top Swivel Set. Top-Down furling is simpler, faster and safer than using traditional snuffer/ socks. It also allows quick, simple furling and redeployment in variable conditions or when gybing.
Proven Design, Performance & Reliability - The Ronstan Flying Sail Furlers have been developed over recent years for use by some of the world's top racing syndicates. Encouraged by their feedback, a number of design enhancements have been incorporated, resulting in the standard range of furlers that now put great performance and reliability within the rach of cruising and racing sailors.
Advanced drum technology- The drum incorporates a sophisticated furling line groove profile and cross hole geometry to grip the furling line securely when furling. This is the same technology developed first by Ronstan for use in the their world leading ratchet blocks to grip line gently but securely. When deploying the flying sail, the continuous furling line self-ejects from the grip zone, remaining stationary for smoother, safer operation with minimum rope wear.
Secure, snag free connections- Furlers and top swivels have retained quick release clevis pins and fairleads have a snag free, flush finish captive pin.
Maintenance free bearing system - Furlers and top swiels feature a factory sealed, maintenance free bearing. Roller bearing sets run on hardened races for smooth high load performance.
Material selection for strength and durability - Hard anodised grade 6061 T6 aluminum construction provides durability and corrosion protection. Grade 2205 stainless steel is utilised for the load bearing shaft for optimum strength to weight ratio.
Multiple attachment options - attachment options include a high resistance shackle, trigger release snap shackle and fairlead, as well as a hard anodised aluminium thimble designed specifically to suit anti-torsion luff line. The furler drum can be adjusted to suit either 0° or 90° attachment, as required to match the take-off alignment and deck layout.
